how do i add a white outline to particles

[zenith wagon]

anyone know/experience why this weird velocity adding happen when im on editor full screen
im trying to make my particle on world coordinate

[wraith vapor]

Is there any node for limiting the distance of a vector3 in VFX graph? If not I'll just make my own.

[clear spruce]

There doesn’t seem to be one. I think this should do it: TheVector3 / Minimum(maxLength, Length(TheVector3))

[safe helm]

try adding the velocity in Output instead of Update

[rotund sedge]

Hey, so I wanna make an effect. This will be of gingerbread men, basically how it will go is skaley summons a whole army of gingerbread men with muskets that shoot out rock hard gumdrops at high velocity, I can do most of everything easy peasy. But, I'm having trouble figuring out how to make the gingerbread men. I know I'd most likely have to take a model and make it, but like. Can I use a texture sheet animation for this? Or maybe some kind of particle. Or if anyone knows some kind of 3d texture sheet animation method. My main goal is i have particles be the gingerbread men and they just walk and aim then fire. But idk how to do all that.......if anything I'll just have to make it a static model which isnt fun.......anyone have ideas on how i can go about summoning a whole board of gingerbread men and make them look cool and full of life?

Btw I cant use scripts since this will be for vrchat

[minor glen]

how do i make a vfx graph control a point light like a particle system?

[rugged willow]

Will probably need to code in a trigger to spawn a light. VFX graph can't spawn lights

[fluid lagoon]

https://portal.productboard.com/8ufdwj59ehtmsvxenjumxo82/c/110-particle-light-output?utm_medium=social&utm_source=portal_share
^ It's an "under consideration" feature - so probably not anytime soon.

[minor glen]

Yea lmao "under consideration"

[safe helm]

you can use CPU Output Events
https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@10.7/manual/whats-new-10.html

[minor glen]

Wont really work out as im tryig to control the lights valve's

Oh wait

I can just use a particle system

[minor glen]

Huh, ill check it out to see if it can do what im looking for

[small dock]

Can a gif animation be used as a particle graphic? If not, can an animation be played?

[surreal elk]

convert your animation/gif into a flipbook texture

[vapid wagon]

Hi everyone, is there a way to see the number of particles emitted with the visual effect graph ?

what I mean is like the particle system, in it you can see the number of particles that are in the scene and is there a way to do the same thing with visual effect graph ?

[fluid lagoon]

[modest bison]

Hi, how to destroy particle FX on collision ? I have rain and when my rain go the ground then the rain go under the scene instead of be destroyed.

[fluid lagoon]

There's a whole collision module - play with the settings there

[modest bison]

I have it but don't look to work.

[fluid lagoon]

It works

give it a high enough lifetime loss to kill it

[modest bison]

wdym ? it set to 1. The rain is under ground it isn't destroyed.

[fluid lagoon]

is that enough to kill it?

how long is the lifetime?

note you also covered most of the module with some popup in your screenshot so I can't see.

[modest bison]

1 ?

[modest bison]

The rain is under ground it isn't destroyed.

[safe helm]

in VFX control you can debug for Alive & Efficiency

[vapid wagon]

Tanks, I'll check it, seems interesting for some debug in code 👍

[vapid wagon]

Hoo that's what I was looking for 👍

Thank you 👍

[urban lagoon]

Hiya people, could someone lend me a hand on figuring out if it's possible to export the frame by frame texture generated by the shader? And how one could do it? Appreciate it, cheers!

[warm torrent]

I don't know if it can be done directly
You may have to record the effect into a video, convert to image sequence and compile to flipbook sprite sheet
Unity has a recorder of some sort, I believe, and there's also the VFX toolkit available which can export sprite sheets out of image sequences

[zenith wagon]

can i make Start() and Stop() function work in constant spawn rate (vfx graph)

[small dock]

THANK YOU!

[true obsidian]

is it possible to make particles in a 2d environment sort by position rather than only by their sorting layer? I have a fire effect and I need the smoke to render behind the fire(and I need the additive particles to always render on top), but I don't want all the smoke to render behind all the fires but rather to have some sort of depth to its layering. You can see in my screenshot it looks pretty bad. I also have the issue of not being able to have the player render in front of the fire when standing in front and behind it when standing behind

but if I change them all to the same sorting layer it kind of screws up the layering of the particles relative to their own game object

where I would like it more like this:

[vestal urchin]

I needed to switch from the Universal Render Pipeline back to the default renderer, but when i did all my particle system textures turned to pink, how do i fix this? Unity 2D

[warm torrent]

Particle systems have various sorting mode options in renderer module I think

[lone elbow]

• I use sprite sheet to animate my system, yet particles i see on the image and those in system are different. Legacy particles additive shader on the material. White sprites is what i see, grey ones is what should be here

[warm torrent]

That's what "additive" does
Why legacy shaders instead of the common particle shaders?

[lone elbow]

• That's what tutorial told me to use. What should it be instead?

[warm torrent]

Whatever render pipeline you're using should have particle shaders which support various blending modes

[small dock]

I had a friend over who never used Unity and doesn't know how to program. He made these particle effects with 1.5 hours: https://www.youtube.com/watch?v=OvWg26tcaps

[warm torrent]

You've advertised this thing countless of times already
It's getting to the point of spam

[true obsidian]

Yes but it's absolute for the particles as a whole, where instead i want it to take something like the y axis into account. For example even if i have my player on the same sorting layer as the particles they will always render under the player even if the player is behind them or in front of them

[warm torrent]

That's a different sorting layer from what I'm talking about
"Sort mode" lets you specify how particles inside of the system are sorted

Particle systems as a whole also have order in layer / order in layer, which take precedence over distance from camera

If you want to draw particles over other objects by depth, they need to have the same sort layer and order in layer

https://docs.unity3d.com/Manual/2DSorting.html you can read the specifics here

[true obsidian]

interesting, thank you I will have to play around with it!

[small dock]

Ok, I can't talk about my particle effect progress ever. I haven't posted in a week. I think I posted 5 videos ever here total on discord on my progress.

I feel like you guys just don't like me.

We have a forum dedicated to building up indie devs, but when indie devs share their stuff and collaberate, why would they get backlash? I'm out.

[dapper gulch]

My VFX graph particles are rendering behind a object even though the particles are in front of it physically? The particles then render correctly if my camera plane is clipping through any object? Any thoughts lol?

[delicate elbow]

Hi ✋🏻 How can i move vfx particles to an object
Which nodes should i use and how 🙂

I think i need distance for this but... Idk how for now.

*Alright, its done :)

[safe helm]

if you select the vfx graph asset in your project you'll see all outputs in the inspector, you can arrange which output to be rendered before the other

[opaque sluice]

when my particles overlap with my ocean, they disappear

anyone know why this happens?

particles use URP unlit shader and the ocean is a custom shader

[warm torrent]

Transparents are usually sorted by their object origin
That would cause this to happen if the origin of the ocean is closer to camera than the origin of the particles

[opaque sluice]

Even when I'm closer to the particle emitter, it still happens.

[warm torrent]

There are several other ways transparents use for depth sorting besides that

[opaque sluice]

It appears that it's doing it with the windows on my buildings as well.

[prime cipher]

Hey, do you guys know any tutorial for wind particles? I want something similar to the wind that comes when a bird moves its wings

[true obsidian]

So this problem was not as simple to solve as it had seemed. I had to go into my URP 2d settings and add a custom axis sort(0,1,0), then make sure all my objects were on the same drawing layer by default. Then, I had to also add a sorting group to the parent object that contained all of my particle emitters for the fire. After that I had to reorganize my children emitters in the hierarchy to sort out their proper sorting(having the smoke behind the fire, the additive colors in front)

so thanks for your help 👍

[wind cloud]

Hey 👋
Does anyone know whether it's possible to pass meshIndex through EmitParams without using meshes? I am just trying to send a simple float through to the shader. But it seems that the meshIndex is not sent even if specified in the emit params

[wise mortar]

Hey, how do I make that particles are at start rotated as a parent but they will keep trajectory and won't rotate as parent after that hm ?

Because now when i rotate car, all of the particles rotate with it

[wind cloud]

Simulation space should be World instead of Local

[wise mortar]

it is world

[wise mortar]

and renderer is world too

and it is like this

[merry snow]

I could just be dumb, but how do you actually use the flipbook player for the VFX Graph?

Like, where do I even put my texture sheet animation?

[tropic forge]

this pop up window keep asks me over and over

even I've choose one of them

I might think if this is an anomaly

[surreal elk]

In the output node, change uv mode from default to flipbook

[hollow jolt]

Hi, is there a way to completely unparent particles from the emitter?

I'm in VR and using particles for a spraycan.
Setting the simulation space to "world" helps as it should, but when I move my hand particles are still being influenced by my hand movements.

Maybe there's another/better way to do this?

[hollow jolt]

FWIW: Apparently using the "Velocity over Lifetime" module would cause this issue, I turned it off and used "Start Speed" instead and now the VR hand does not influence the particles anymore after being emitted

[stoic ore]

How do i get the Collide with AABox node to show bounds when resizing the size throuigh the scene window?

[surreal elk]

use the world mode (press the "L" in AABox block, not the whole system)
then click AABox node, it will works

[stoic ore]

I pushed L but don't see anything changing...

Hold up, I can see it in the scene view now, thanks

I have another question; should a rain particle system be static or should it follow the player around?

[fickle iron]

Hello, how to save the rate? When I put it at 4000 it comes back to 100

[ripe cave]

is it possible to put multiple sprites in a particle ?

[left tide]

Does anyone know of a way to have multiple particle strips at once using the VFX graph?

[left tide]

I'd say, probably follow the player. I doubt you'd want it raining on the entire world all at once

[warm torrent]

Raindrops become visually indistinct and turn to fog over a distance anyway

[left tide]

It's more for the performance benefit of only simulating rain around the player

I'm not sure of the performance issues of having one huge particle system but I think it'd probably be better to simulate the rain around the player. If you do it over a big enough area, it should look exactly the same as doing it across the entire scene

[warm sequoia]

https://youtu.be/KWTS9KrRxSI

Does anyone have any idea how these pulsar jets could work

I assume it's mesh effects

but it looks.. perfect

[glacial badge]

Hey, I'm trying to make a laser using line renderer but I keep having this weird lag:

[clear spruce]

Is the line renderer part of the gun (child)? If not, what method you use to move it? Update? FixedUpdate? LateUpdate (you should use LateUpdate)

[glacial badge]

late update?

ok

i was using updaate

it is parented

OMGAH

thank you

[clear spruce]

Its called after every Update is executed. That means if you rotate the gun in update, the laser will use the new gun position instead of (possibly, depends on script execution order in which order Updates are called) old one

[glacial badge]

oh

i dod not use it because i thought it makes it a frame later

[clear spruce]

No it doesnt. Its called in the end of the frame (still before rendering is started etc.)

[glacial badge]

okkk

[clear spruce]

You can see chart for the update cycle stuff here: https://docs.unity3d.com/Manual/ExecutionOrder.html

[clear spruce]

Parented to the gun? Are you still updating it yourself? I think you could just use local space mode for the LineRenderer

[glacial badge]

it worked in lateupdtae()

[hollow jolt]

Hi, is there a way to render a particle system over everything on the screen of a 3d scene?

[fluid lagoon]

render them on an overlay camera

[hollow jolt]

Do you know if this would work in VR? Forgot to mention it.

[fluid lagoon]

why not

[hollow jolt]

I just found only URP related stuff that had some issues (I'm using built-in pipeline), but will try this, thank you!

[hollow jolt]

The overlay aspect seems to work but now the original VR cam is upside down

[pastel obsidian]

I don't quite get the particle system, how do I make it so that when the object moves it leaves a trail? The particles just move with the object instantly

[clear depot]

Set the particleSystem's simulationSpace to "World"

[pastel obsidian]

Oh thx

[lofty pebble]

I am having problems with particle system. I added custom image through particles/additive and now the picture literally looks like this as a particle. How can I get rid of the whiteness

[wanton geyser]

Open the picture in a photo editing software and cut the background out

[full olive]

trying to change alpha on particles in HDRP/lit shader. doesn't work. any workaround? googling took me nowhere thus far

EDIT (solved): used visual effect graph instead. brackey saved me again. legend.

[lofty pebble]

is there a way to change bounds on the particle. Because my particle has huge bounds but is very small and it bounces in mid air from the ground

[warm torrent]

Bounces as in by particle collision?
Collision module lets you define the collider size

[lofty pebble]

Youre indeed correct, thats whre you define the size, thank you

[uneven ridge]

I have a Problem with VFX Graph. I can't see the particles in the scene whether in Edit nor in Play mode. I created a new graph an dragged it into the scene. I have searched for it but nothing seams to work. Does anyone have an idea what could cause this problem ?

[prime dome]

How do i make my Trail look pixel-ish? It kinda works with the pixel perfect camera but i really dislike the pixel perfect camera so i wonder if there are different ways to pull it off or if i should just write my own trail renderer kinda thing?

[vast yacht]

how can i make a grass looking particle.

[dull obsidian]

custom HLSL block moved to officially "planned" status on VFX roadmap

[hard spade]

when using unitys particle system and emitting in the shape of a mesh renderer the color of the particles is a result of the meshrenderes color and the particles color. Is there a way to emit in the shape of the mesh renderer without adding on the color of the mesh renderer to the particles?

[tepid violet]

Hi im trying to create a particle using albedo but my material is pink, i installed render pipe line, how can i fix this please

[prime dome]

Why is my VFX Shader graph not animating the texture of the particles? it just stays still

[inner topaz]

in the scene view ?
in case that it you need to enable this option for the scene view

[prime dome]

it worked

thank you!

[digital valve]

If you are using a Universal rendre Pipeline you have to use the proper shader : urp particle

[dark kestrel]

How would I achieve a delay per particle in VFX graph. For example I spawn 3 particles, particle 0 = 0 sec delay, particle 1 = 0.1 sec delay, particle 2 = 0.2 sec delay etc

thought this would do it

[safe helm]

I think you can use constant spawn rate of 1 particle with 3 loops and set before loop delay to 0 sec and after loop delay to 0.1 sec

[full olive]

where's the prewarm option for vfx? not in inspector..?

[stoic ore]

Hello. I have a rain particle made with vfx graph. I've set the gameobject that's contains the particles to my player so that the rain follows the player position. But the issue with that is that the particles also "follows" the player as well if you know what I mean. Does anyone know of a way to offset particles?

[clear spruce]

You can move the particle system with the player and use world space mode

[stoic ore]

Thanks, that seems to give the effect that I was looking for

[opal star]

I need a little bit of help. I"m trying to spawn particles following a path defined from a Multi Position binder. I followed a thread on the forums to begin with but I want to sequentially spawn the particles. This is the forum thread where I started from https://forum.unity.com/threads/particles-along-polyline-assign-point-cache-asset-using-c.883462/#post-6122468

[rotund sedge]

hey im using final ik raycasting and for some reason im having an issue with it where i have it at a wand tip, and sometimes it just doesnt aim the right direction, sometime sits aiming towards the place i want, but then most of the time it goes 180 and goes out of the back of the wand and im not sure why its doing a 180

[surreal elk]

There is a node called "Sample Multiple Position Map". (You have to import additional blocks from Package Manager > Visual Effect Graph > VisualEffectGraph Additions) then modify the "Progress" between 0 and 1.

[opal star]

Thank you it does exactly what I want haha

[plucky path]

Yup he's definitely a scammer or smth

Maybe a bot.

banned 👍

[short shoal]

Hi everybody I was just hoping someone here could tell me if VFX graph is okay to use now on URP for mobile? Sorry to bother the documentation's a bit hard to find and a tad contradictory on the forums.

[clear spruce]

it seems vfx graph doesn't support any mobile devices yet. unity is working to get support on high-end mobile devices but the support will include only compute cabable devices (vfx graph relies heavily on compute shaders so devices not supporting them will not work). For now, you should use the built-in particle system (shuriken) instead

[tropic lichen]

are there any other options to enable to make VFX play in scene view/edit mode

[unique copper]

Hello! I’m an absolute beginner and would like to learn to utilize Unity’s particle system. Are there any recommended tutorials?

[desert saffron]

do I call OnParticleCollision() on the game object that was hit or do I call it on the game object with the particle component?

the documentation is confusing

I want to get physics info

[warm torrent]

I think all On Collision events are sent to both objects generally

[still sierra]

in my opinion, the best way to learn would be to find a tutorial for a particle effect you want to create. Do this a few times over with different effects and you'll eventually get the hang of it

[unique copper]

I see, thanks!

[fickle wyvern]

I can't put my shader graph in. What can I do to fix this?

Oh ok, I had to enable this

[formal acorn]

my particles arent showing when i reload a scene any known fix

[stuck trench]

What gravity value is the same as RigidBody's default gravity?

[fluid lagoon]

Physics.gravity

[stuck trench]

Okay

[tropic lichen]

FYI, this timescale value also takes effect in edit mode, so if it is zero, Visual Effects will not update.

[prime dome]

how to make particles go up a little and fall down

using vfx graph

this doesnt work

[safe helm]

you can set the Y position in update using a sample curve node

[prime dome]

worked thanks

[astral niche]

Hi there, i'm using VFX graph.

my alpha is set to zero but i can still see my particles. Why is this?

[clear spruce]

at the end of the lifetime it's transparent and fully visible at start?

[astral niche]

@clear spruce it says alpha = 0 ?

[clear spruce]

ah that seems weird. in the image above it was like this which seems correct

[astral niche]

white tab

[clear spruce]

for me this gives fully transparent so maybe its a bug?

[astral niche]

oh i think i had two tabs here that were overlapping by the slightest amount

[clear spruce]

oh, didn't even think that could be possible. that's annoying

[astral niche]

i want to multiply the output color of my gradient, can i do this?

[brisk nexus]

Hi there, I'm making a 2D game with Unity using spritesheets for all graphics and was wondering if I could take an existing VFX effect like this one: https://youtu.be/FvZNVQuLDjI?t=576 and turn it into a .png (no background) spritesheet of around 40 frames

That way it ends up having this png spritesheet structure

[neon adder]

Heyo, quick question, I'm really really bad with particles, I'm just looking to do something simple in 2D, a ring of particles that start from the center and expands in a circular shape, just one row of them but I wouldn't mind having multiple as long as it doesn't get visually confusing

Something like this but the center should be hollow and particles not randomized

Is it hard to make ? Or is there some hidden setting I didn't see ?

Heck I honestly even accept any kind of tip to achieve this, I have no idea what I'm doing LUL

[astral niche]

VFX graph: how do I make my particles move along the shape of the cone that i've provided?

documentation states that the cone shape will set the direction attribute but i haven't been able to successfully use this attribute

the direction attribute simply appears to be zero

for what it's worth i really have no idea what any of this attributes are reading and i don't know how to check it.

that's a lot of zeros. if the attribute was nonzero i'd expect to see some kind of deviation, anything

[opal star]

I think you need to run your set position node before setting the velocity. Order matters.

[astral niche]

oh! you're right, i didn't know that order was meaningful here

[opal star]

It is. The graph is evaluated left to right for operations and top to bottom for the context nodes

[astral niche]

ok so im a little confused with some behaviour here

100% colour components = distortion

zero alpha component = no distortion

exposed property value of 0 = distortion ?

why is this happening?

[jolly heath]

hey guys, trying to learn vfx graph, how do I see the bounds preview in my scene viewport? Cannot see anything when I select it
EDIT: closing and re-opening Unity fixed the bug...

[buoyant meadow]

Hey I just want to double check before I try, is it possible to make a particle system but only write particles to it through code. I want to be able to ray cast a bunchand spawn a particle where they land.

[atomic magnet]

Hey so I'm trying to make a very specific effect in 2D with a particle system

I want 4 particles to spawn on a burst, from a single point, fly in four directions, then return to the center.... I could do this very easily with tweens if they were game objects, but trying to do it with the particle system interface is turning out to be such a headache... is there an easy way to do this? or should I just make them game objects instead of trying to do it with particles

[elder latch]

Does anybody know what would be the best way to rotate a whole batch of particles around the center via parameter?

E.g. spawning particles in a sequential circle and then rotating the whole circle of particles?

[elder karma]

Particles appear bigger

[jolly heath]

you can rotate the transform of the attached gameobject and the particles will rotate if they are in local space right?

[elder latch]

Yes that would work, but I only want to translate some vfx stacks and not all and it is easier to animate via parameters.

But I actually found a solution. I just needed to rotate a direction vector and put it into the up parameter of the circle sequence component

[granite cairn]

I'm running into an issue where in editor, my VFX graph works exactly as intended. When built to the Oculus quest 2, the particles are only visible when I get the player very very close to the particles. From my testing, the bounding box is seemingly not the issue, so I'm not sure what is?

the particles appear to "fade in" as the player gets closer, rather than simply appear or not appear

[delicate elbow]

Hi! How can i change my particle effect's startColor to my gradient with script?
When i use main.startColor it only shows the first color of the my gradient.

[jolly heath]

you can sample the gradient using a float (proportional to time if you want it to scroll through the gradient) and give that to the main.startColor

[delicate elbow]

Thanks a lot.
I just fixed with using MinMaxGradient and select the true mode from Inspector.

[stoic ore]

Trying to find a word for this thing; in Deus Ex (the old PC game) what do you call that animated box thing that shows up when you look at an object?

for context: https://youtu.be/owJCi4ge5-Q?t=4027
that white box outline when the player is looking at an interactable object

[zinc goblet]

boxy highlight?

or ah. squarey highlight

[ember gate]

Black hole bomb effect i made (ik its very simple but i think its cool)
[Epilepsy and Volume warning]

camera shake could use a lil tweaking

[royal maple]

lil bit

[desert saffron]

how are particles on hit usually done?
does every enemy have a particle system component
or is there an object pool for particle systems an object pulls from?

whenever an enemy gets hit

[fluid lagoon]

If you want to be efficient about it, use a single particle system and call Emit when there's a hit
https://docs.unity3d.com/ScriptReference/ParticleSystem.Emit.html

[desert saffron]

what if there's multiple hits on multiple objects

would that still work?

[fluid lagoon]

You call Emit once for each hit

yes

A simple way is basically make a ParticleManager singleton, and have the code that handles enemies getting hit call a method on that which calls Emit on the single shared ParticleSystem

[desert saffron]

cool

[fluid lagoon]

That's how I did all the particles here: https://www.youtube.com/watch?v=C4E_mIsEa7s?t=128
Notice they all have different colors and spawn at different positions. That can all be done with a single system

[desert saffron]

its working but I don't get why the position is way off

        ParticleSystem.EmitParams emit = new ParticleSystem.EmitParams();
        emit.position = transform.position;
        emit.velocity = ((Vector2)transform.position - pos) * 3;
        particles.Emit(emit, 1);```

ah i had to make simulation space to world

[rancid osprey]

I made a sleeping particle effect that makes z go up in a line, but i want to be able to disable it but still let the particles fade out

[cloud crane]

im getting this error after downloading VFX:

whatever it is, its making my particles not show up:

after restarting unity, i now get this error:

"Shader error in 'Hidden/VFX/CannonParticles/System/Output Particle Quad': Couldn't open include file 'Packages/com.unity.visualeffectgraph/Shaders/VFXCommon.hlsl'. at line 2395"

this was fixed by changing project settings > player > other settings > color space to LINEAR

[cloud crane]

does the "Add velocity over life" node not work? if got the right side of this curve set to 300 but it still doesnt effect the particles at all

[cloud crane]

what could be doing that? the only changes ive made from the default particle list is changing the spawn mode to burst, adding a set angular velocity, and then the add velocity over lifetime

[surreal elk]

If you want to modify velocity, you should do it in Update instead of Output

[lost dagger]

https://youtu.be/7tazneZxmHU is this same motion blur still supported in newer versions of unity pro or is there anywhere else to find it (figured it probably goes here)

[tough nexus]

Hopefully I hit the right channel for this. I have some problem with the Linerenderer and I do think I might not fully understand it.

I have a Point class which holds some information such as a Vector3, color, and other data that I need elsewhere. I will have a list of up to 1.2k points per frame. the points are also already sorted.

Now what I want to do is to draw a line from point to point. The line should have a color gradiant such as: startcolor = point1, endcolor = point2

I have tried several ways to draw this line but all with weird problems.

renderer.positionCount = points.Length;
for(int i = 0; i < points.Length; i++) {
  int nextIndex = i < points.Length - 1? i + 1 : 0;
  renderer.material = mat;
  renderer.SetPosition(i, point[i].position);
  renderer.startColor = point[i].Color;
  renderer.endColor = point[nextIndex].Color;
}

What this does is it actually draws my line but there is no gradient between 2 points. Instead the color for the whole Line will switch

Does anyone know how to fix this?

[rigid mesa]

@tough nexus you don't have anwser and i never try this .. if you try with hardcoded value thats work ?

Question here i need to understand something beetween particle effect and shader ..
when i had an shader like a diffuse or a standart one i cannot interact beetween particle effect menu (like color ) and shader .. but of course shader mobile work
i don't find any information on this how i configure my shader to interact with particle effect

  BindChannels {
                Bind "Color", color
                Bind "Vertex", vertex
                Bind "TexCoord", texcoord
            }

[lost hill]

Hi all, I'm working on a HDRP project and I'm using shadergraph and vfx graph to make some simple FX.
We're looking at using HDRP volumetric fog, however I've found that when I'm using a shader on a vfx graph effect that has something plugged into the alpha channel, it renders black when the camera is far away in fog.
Its hard to tell it from the picture but on the right I've got the same particle but without anything going into the alpha channel in its shader and it reacts as expected to fog.

Is there any way I can get a vfx graph shader to react to fog as you'd expect: disappearing when the camera is far away and re-appearing when closer?

[rigid mesa]

you can create fog only with volumetric rendering .. and use raymarching to create your shader .

[lost hill]

Yeah I've added a fog volume, that picture is with a world fog volume enabled and set to an attenuation of 1.. its just the particle FX I've created render black when the camera is far away from them

I'd expect them to disappear into the fog when I move the camera away?

[lost hill]

do you think raymarching is the solution?

[rigid mesa]

I don't know about your solution but I have seen perfect effects with this technique ..

if it's on pc and not webgl or mobile i think ... in webgl you can have surprises (bad) @lost hill

[lost hill]

Its only for a windows build; I'll look into raymarching to see if that helps. It's just weird that if I take any alpha texture away from the shader then it works as I'd expect.. :/

Thanks for your help @rigid mesa

[rigid mesa]

thats not an easy topic

good luck

[fringe perch]

How do i do a simple particle that just spawn one sphere

i tried to change texture

but it went invisible

[brazen grove]

How do I access burst settings through script?

[fringe perch]

why its white sometiems

[tiny pelican]

hi guys, for some reason the particle effects i used for my vr project worked well in the editor, but when I build it and tried them on the headset, they became broken(like they were twisted). I think its either because of the cameras not setting correctly or it's because i didnt have render pipeline not installed. Any help would be appreciated.

[split hornet]

hi, does anyone have any resources / tips for creating localized darkness? I want to have sort of a black shroud that follows a creature and darkens realtime light around it. would this only be achievable with a shader?

[opal star]

Does anyone know if its possible to exclude a bunch of operators from being computet in a vfx graph with a bool? I dont think the branch node does this exactly since it will simply supply a 0 and all the math will still be done .

[clear spruce]

If you want that to look good, i think shaders are going to be involved anyways. Could you do that using decals or something similiar?

[split hornet]

i’m thinking about using some sort of volumetric fog on top of a shader

[brazen grove]

Is it not possible to access the particle system emission burst probability parameter through script?

[cloud crane]

for some reason, my particles dont work when Project settings > player > color space is set to gamme, and i need the color space to be gamma to export to WebGL

and by dont work, i mean they just dont show up

ok, testing, now they dont work on iether color space

hitting play just does nothing

To clarify, test is a newly created default VFX

[native perch]

Hi ! When i make my dust particle spawn when i walk, they look streched with a blur around it. How can I fix that?

[fluid lagoon]

you probably have the particle system on a scaled object

or an obejct that has a parent that is scaled

[native perch]

I do yes, is there an easy workaround ? I am really bad at coding...

[fluid lagoon]

nothing to do with code

fix your hierarchy so there's no scaling

[cloud crane]

So far ive tried reinstalling the VFX graph package, restarting unity, and restarting my PC. Anyone know any different solutions?

ok, so i switching my build from WebGl to windows, and now the VFX graphs work? Does VFX not work for WebGl?

[slate raft]

How can I use ParticleSystem.Simulate to simulate a case where particle system stops emitting for a period of time while keeping previously emitted particles alive? At runtime, it's trivial to do via Play (withChildren) and Stop (withChildren, ParticleSystemStopBehavior.StopEmitting), but I don't see a way to replay such a scenario via Simulate - simulation doesn't have a concept of emission being on or off. A simple example would be a looping particle system emitting dust when wheels of a vehicle contact the road, triggering Play on start of a contact and Stop on end of a contact. How do I replay that dust, including breaks in its emission, via Simulate?

[native perch]

After multiple tests i can confirm all my object in my Hierarchy have no scaling, Its weird, when i play, sometime its does the stretching, sometimes it doesnt. If you have any other idea of what could cause this, it would be appreciated, thank you for the help provided so far !

[strange sail]

If you are using built-in or URP, you can use a script to give a light negative values by giving it a negative HDR colour. That will only affect lighting, so you might still need some sort of particle effect if you want it to obscure/occlude stuff.

[timid spindle]

what time measurement is start lifetime in?

i put 15 but it doesnt stay for 15 seconds

[strange sail]

Your particle system duration has to be long enough too, not just the particle lifetime.

[timid spindle]

but it stays for longer than 15 seconds, not less, i tested it an apparently its two times a second for some reason

[heavy bane]

Hello, any idea why my particle system which is child of another object would emit from the wrong position? The particle Gameobject is at local position zero, however the particle emitted is starting way off to the side.

it is exactly this problem: https://forum.unity.com/threads/particle-system-emits-from-wrong-location-when-its-a-deep-child.699011/

[fluid lagoon]

are you simulating in local space or world space

[heavy bane]

world space since particles need to fall into the world

If I set it to local the origin will be good but particles will be affected by the parent of the particle system once they were fired and this doesnt look good

[heavy bane]

Here is an example:

https://i.gyazo.com/5c2b183b2e2a408f0896f1bc9d0288c7.gif

[round oyster]

anyone know why my particles would be spawning from a weird angle in world space?

@heavy bane did you ever figure it out

[heavy bane]

Not exactly, it seems like a bug but I have a workaround

[round oyster]

Oh? what is it

[heavy bane]

I can spawn particles in the world, with no parent, then to make them follow the origin they need to be following I use a script that just follows the position and rotation of a target

either that or a fixed joint should work

this way your particles can live in the world using world space simulation and still be attached to whatever origin you need

[warm torrent]

Parent Constraint is meant for this purpose
If that works there's no need to use joints or physics

[heavy bane]

The issue with parenting is that is causing the bug of the particle not starting at the correct origin when using world space simulation

[warm torrent]

With the parent constraint component as well in addition to parenting?

[heavy bane]

When you say parent constraint are you referring to move the particle as a child of a parent gameobject?

[warm torrent]

When I say parent constraint I mean the component by that name

[heavy bane]

mmm just tried it but it seems there is still an offset

[warm torrent]

I suspected it might've inherited the problems of parenting but it was worth a try

[heavy bane]

yep, thanks

[verbal junco]

Ok, so this is frankly awful. I'm trying to create a 2D game using a VFX graph, following a tutorial, but it seems the VFX graph doesn't work in 2D?! Even after installing the latest version of Unity with a 2D Render Pipeline, the particles still don't show up, which sucks cuz this is kind of central to what I'm working on.

Can't really switch to 3D either as I need other 2D stuff. Does anyone have any ideas here?

[safe helm]

the Universal Render Pipeline’s (URP) 2D renderer is supported in Unity 2021.2 or higher (VFX Graph v12.0.0)

[verbal junco]

Yeah, I have 2021.2 with a 2D Renderer pipeline but it still doesn't do the thing. 😕

[plucky path]

Wow, those are some blazing armpits

[lusty tinsel]

hello
I'm trying to do a (2D URP) flamethrower particle system in which each particle has a custom color based on the direction to use it as a direction map to multiply the distortion map so it no only shows heat distortion but also direction
I have already sorted out the color by angle part, though every particle's color updates unanimously as I shoot and I want to keep each particle's initial color individually, anyone knows how I could do it?

[warm torrent]

You can use custom vertex streams to send info about the particles to shaders

This way you can use the each individual particle's streams as the direction map, and use particle colors for colors as normal

[lusty tinsel]

oh I see thank you a lot

however what if I want each particle as a game object (for collisions for example)

and damage dealing and all of that

[warm torrent]

You can get collisions and collision events from particles just as well

[lusty tinsel]

ooh I didnt know that thank you

ill test it then thx a lot

[dark kestrel]

In VFX graph, how would I spawn a single burst of say 32 particles but with each particle on a slightly random delay?

this seems to make them all delay together

[safe helm]

I think you want to use the constant rate block but change the spawn context to have 1 loop with the duration and delay you want

[dark kestrel]

Got it, thank you!

[limpid orbit]

Hey, I have a question. So I have this enemy I've made who is completely covered in particles as part of its design. The issue is that the particle system I've made is pretty extreme and emits a LOT of particles in order to fully encompass the enemy in a way that also fits around it's mesh very tightly and updates quickly with the enemy's animations. Because of this, the game lags sometimes and in some cases the particles on the enemy just disappear before reappearing later (I'm guessing because Unity exceeds its particle limit as this happens consistently when my player gets near any other particle system). Several particle systems are a part of this enemy and only one is immune to the disappearing effect, and it's the only one that isn't bound to a custom mesh. I'm wondering if there's any way to change the settings of the particle system in such a way that the design isn't altered to a noticeable extent while reducing the strain of the particle generation. And if there's a way to somehow convert the particle system into something else like an animation if that's even possible? Since the actual particle system itself is only really there to cover the "skeleton" of the enemy, I don't find the need to generate each particle individually necessary at all, if that makes any sense. Any help would be appreciated. I'll provide some screenshots showing the enemy and the particle system settings.

(sorry accidently sent that instead of pressing shift+enter)

• The first image above is what the enemy looks like when everything is working
• The second image (below) is what it looks like when the particles disappear (except for the one particle system selected that doesn't disappear)
• 3rd, 4th, and 5th images are the settings for the main body particles (the ones that disappear and lag the game sometimes)

there are also particles for each individual tentacle thingy and they have very similar settings to the main body particles (it's hard to see them in the screenshots but their effect in game is very different)

[warm torrent]

@limpid orbit how many particles do you have active exactly?

...probably the maximum 4000, considering you're spawning 400 per second and they live for 75-100 seconds

If you want the effect to be stable you shouldn't be keeping more than the limit of live particles

With a lifetime of 10 you would always be at stable 4000

If you need more than a couple of thousand particles, the VFX graph works much more efficiently and effectively
Usually in these type of situations you wouldn't rely on just particles to cover a character, but you would also modify the mesh and use a shader to make the surface seem nonsolid and ephemeral

[opal star]

With the vfx graph you can absolutly cover a mesh with particles

50k to a 100k would be ok on new hardware

Shuriken was defo not made for this

[limpid orbit]

Ahh ok. I don't think I've used a VFX graph before since I'm still kind of new to some things in Unity. I'll go look up some tutorials. Thank you so much!

[opal star]

@weak wraith again the vfx graph is really great for this. If the camera is outside the systems bounds it gets occluded, its easy to set up a world space sim too and you can have dense particle sims

[opal star]

You dont get a global volume for weather. What we do is move a rather tiny volume with the player

[native steppe]

Can someone explain to me how to get particles to propel themselves from a point outward in a random direction (spherical) very quickly in the first moments of their lifetime and then kinda stall/collect near the edge? I tried using a sphere mesh for the shape and then setting velocity over time curves so that the velocity was at 1 for a short time before plummeting to 0 but it's not having the result I expected. I think I have some fundamental misunderstandings about how these different properties work.

[limpid orbit]

this might be a bit of a silly question, but is it possible to "convert" a shuriken particle system into a vfx graph, and if so how do I do that?

[fluid lagoon]

Manually

[limpid orbit]

I kinda don't have much experience with vfx graphs at the moment so I'm not sure what you mean... Do you mean I have to remake the particle system in vfx graph from scratch?

[rigid harbor]

Hello,

I would like for my trail renderer to change material if my statement is true, everything works except for contacting the trail renderer, material1 is assigned.

but i dont know how to write the code to contact the material list of the trail renderer, for him to tell him "hey change the material to material1"

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Red : MonoBehaviour
{
    SpriteRenderer renderer;
    GameObject playerSetTag;
    TrailRenderer t_renderer;
    public Material material1;



    void Update()
    {
      playerSetTag = GameObject.Find("Player");
      renderer = GameObject.Find("Player").GetComponent<SpriteRenderer>();
      t_renderer = GameObject.Find("Player").GetComponent<TrailRenderer>();
    }

    void OnTriggerEnter2D (Collider2D redCollider)
     {
       if(redCollider.gameObject.name == "Player")
       {
         playerSetTag.tag = "Red";
         renderer.material = material1;
         t_renderer.materials[0] = material1;
         
       }
     }
}

thank you

[ionic wagon]

guys i wanna make clouds for a pretty large map

any specific way to do it ?

so ican follow it

[clear spruce]

If you want be able to fly through them, you most likely need to use ray marching shader to achieve that (check this https://youtu.be/4QOcCGI6xOU). Clouds that needs to be seen only from ground can be done using skybox shader (similiar to this https://youtu.be/sXevaQ8cM2c)

[ionic wagon]

thanks ! i used some assets and they suck since the clouds were limited on an area and not the whole scene

[prime dome]

im getting this issue and i guess that is why vfx is not being visible

[autumn lagoon]

I have a particle system running a trail that follows the mouse when you click

if I release the mouse button to stop the trail, and start the trail somewhere else, it connects itself to the end point of the last trail

[rotund sedge]

https://gyazo.com/2578e22684ddd5fa75e8145e437258ba

https://gyazo.com/a0a4471e61df6752aaf0ff9723ac6ee4

so i wanna make a beam like this

but im trying to figure out what i can do to make a beam leave behin the golden burn as you see it put on top of the stuff that gets blastes

like its melting or leaving a trail behind, im struggling to figure out how to amke it

[autumn lagoon]

Have you tried spawning "burn" prefabs in the places the beam hits at?

[opal star]

Decals is normally how its done

[low cedar]

hello, how do i implement a trail of dust when walking in a top down game?

[twin remnant]

Hey, I need help with particles forward decals node,
vfx system is generating mesh for it on a plane, but it renders nothing

[twin remnant]

now i have something like this, im really confused

[twin remnant]

thats the whole vfx graph

[knotty cedar]

made this vfx and need it to kick the player aside when he moves through the smoke

is there a mesh collider using vfx like with the part icle system?

or do i need make a second gameobject which kicks the player to the side?

[twin remnant]

ok i fixed it, it was rendered in wrong camera

[warm torrent]

The CPU has no knowledge of where VFX particles are or what they're doing, which would be necessary for colliders
That's the main thing that separates VFX graph and shuriken particle system

[twin remnant]

Im making bullet decals using vfx graph
Is there a way to still spawn decals after reaching max capacity without setting it to absurd numbers?

Like is there any option to delete the oldest particle to make space for new one

[loud tartan]

Can anyone think of a reason why when I scale down the parent gameobject of a particle system, the number of particles that a sub emitter emits is reduced? None of the other particle system attributes were changed

[fluid lagoon]

is it using emission over distance or something

[inner topaz]

why not track it in the decail spawner / a decail manager remove the oldest onece once the limit is reached

[loud tartan]

It was lol, figured it out earlier but thanks

[elfin oyster]

Hey, I am learning VFX, I am using this flipbook but why does it look weird? THe box surrounding the image

Oops nvm

[grim jasper]

Can anyone help me, I'm new to unity and I'm trying to cover an object in fire but don't know how to do it

[latent rampart]

no offense, but you should use youtube instead of asking here 😉 Search vor something like "unity fire vfx" and you get videos en masse

[latent rampart]

You should make use of the alpha channel

[main viper]

How can I access the collided Particle in OnParticleCollision/ Get the Index?
I'm able to get the ParticleCollisionEvent but I'm trying to get the actual Particle

and searchin it using the position sounds terribly in efficient

[warm torrent]

Probably can't
Why do you need it?

[main viper]

I'm trying to make particles stick to vehicles but i guess i could just spawn a Particle in a local particle system(on the vehicle) at the intersection point

Thats just not as clean as I would've hoped

[main viper]

Would it be possible to loop over the particles and just check if they've got a collision

[warm torrent]

I guess it might be but it does sound very inefficient
You'd be better off spawning "stick" particles at the hit position with sub emitters, for example

Might not even need scripts

[main viper]

would that work if the vehicle is moving?

[warm torrent]

Ah right, that probably needs scripting in some way

You could instantiate the stick particles at hit position from collision event and parent them to the collided object

[main viper]

that sounds good

would that still be a good idea with multiple vehicles?

I dont know how performant particle systems are

[warm torrent]

Depends on the number of particles and collisions

[main viper]

ok

Thanks!

[silver oak]

Hey, I'm following the tutorial from Brackeys about fire and smoke: https://www.youtube.com/watch?v=R6D1b7zZHHA
He uses a flipbook in a shader, but his download texture is not available, so I downloaded one from https://blog.unity.com/technology/free-vfx-image-sequences-flipbooks
But my flipbook does not have the black parts clipped like they should. I tried to mess with the Alpha Source, and force the format to RGBA, changed to other flipbooks but it keeps doing it. Output Particle Quad is also not documented by Unity so... Anyone has an idea what I'm doing wrong?

[warm torrent]

@silver oak Most of those textures do have alpha
The ones that don't have alpha are probably meant to be used with additive blending
That specific texture is called the temperature map so it's probably not meant to be used as the base texture of the effect, but to determine intensity

In a pinch you can set "alpha source: convert from greyscale" in import settings over there

So you can use this one with alpha

[silver oak]

Thanks, I thought I could use that one to colour them in. So I could have green fire. I'm really new to the whole VFX stuff.
Anyhow, if I use one of the coloured ones already, it is still the same.
It simply does not use the alpha then.

[warm torrent]

There is no alpha

[silver oak]

Even if I force that one to RGBA 32 bit, because for me its weird that its RGB BC6H

[warm torrent]

you can change this to get alpha in a pinch

[silver oak]

Your a hero, thanks! No idea why I needed to reload the scene to make that work.

[plush crypt]

Is there a way to lock VFX particles rotation on a single axis? I've got a bunch of particles spawning along the surface of a sphere, and want them to all face the center of the sphere without twisting whenever the camera moves. Not sure if there's away to do this while still having something similar to a billboard effect, but couldn't find anything online about it.

[silver oak]

Look at position camera?

[plush crypt]

That's what I've got currently. I've tried all the settings in the list actually, but they all seem to still rotate (I think on their Z axis) whenever I move the camera

Have tried both local and world space as well just for giggles

[silver oak]

Then I don't know, you sure you are not overwriting it anywhere else in your graph?

[plush crypt]

The only other thing affecting rotation is the initial Set Angle.Z so that they have an initial random rotation, but even if I turn that off, same thing

Dunno if I should be using a Rotation 3D node somewhere? Still learning VFX Graph so I may be missing something obvious

This is what it does currently if it helps

Face Camera Plane, Face Camera Position, Look At Position, etc. all seem to result in the same behavior

I assumed Advanced, but that only works on 2 axis

Unless that's just me been a noob

[silver oak]

Well I am also just beginning. Have you tried Fixed Axis?

That's the only one I am getting that is not responding to the camera rotating

[plush crypt]

Yeah. Unfortunately while it locks rotation, it locks all 3 axis so it doesn't display correctly

I think it's just the Z axis I need to lock but am not positive

[silver oak]

How about No orient at all? 😛

https://docs.unity.cn/Packages/com.unity.visualeffectgraph@10.2/manual/Block-Orient.html

[plush crypt]

Ha, good idea but then everything is just on one axis. Would be great if I could have them look at world position on initialize but then not update after that... Maybe there's a simple way to do that and I just need to play around with it more

[silver oak]

The docs say Look At Position should work...

[plush crypt]

Yeah that's what I thought... Not sure why it's still having that effect

Though I've fought against all kinds of inconsistent or otherwise confusing behavior with Unity. Just seems to come with the territory.

Not unheard of that this could be a glitch

[silver oak]

Yeah had the same problem 2 hours ago when my materials where not updating until I reloaded the scene

Well I honestly have no idea how to fix it. Maybe someone else can help you.

[plush crypt]

No worries, I appreciate your suggestions

It's the last piece I need to work out before I can finish it and move on lol

[plush crypt]

In case anyone else sees the issue above, here's an opaque quad version for easier debugging

[barren trout]

What software should i use to make vfx

[clear spruce]

Unity? Vfx graph? Shader graph?

[silver nova]

so i wanted to ask a question

ive been searching for but couldnt find the good answer

how to trigger a particle system using OnTriggerEnter

[fleet hill]

guys how to make the particle goes to left

i mean direction to left

landscape

[midnight grove]

Rotate the particle system

[fleet hill]

hey

can anyone teach me make particle fire rocket system

wait

@midnight grove

how to make the particel fading ?

like after it spawn 1 sec after it fading

sorry ping you

ahh man its hard to make particle system

[midnight grove]

I'm not here to help you make a particle system. Use the Color over Lifetime setting and change the alpha of it to fade out. If this makes no sense, then you should look up how to use the particle system in general before trying to make something yourself.

[barren trout]

Can any other software be used

[clear spruce]

You mean vfx you can then use in unity games?

[barren trout]

Ok

[clear spruce]

Yes or no? 😅

[barren trout]

I was just wondering if you could use other software for vfx then import it in unity

[clear spruce]

I dont think thats possible

[barren trout]

Ok

[warm torrent]

Some effects made in Houdini and alembic files from various programs can be imported
But that's not really something you need to worry about unless you're already pushing the limits of VFX graph

Does someone have an idea why my vfx effect doesnt render in my game-build?
All VFXs are working except for one of them D:

[visual cove]

Could anyone point me in the right direction for using random meshes in VFX Graph. Tutorials suggest it should be an option in the inspector but I'm not seeing it in 2021.2.7f1 has it moved?

[visual cove]

If anyone else encounters not being able to see this option in the inspector, I was able to work around this issue by going into debug mode in the inspector and setting the value there, then forcing a recompile of the graph. That got them to show up in the output node.
The feature seems to work fine so I'm assuming this is a bug.

[visual cove]

Or just turn on experimental settings 🤦‍♂️

[shell garden]

k

[opaque plank]

does anyone know how to make sub emitters take the normal of the collider surface they hit and rotate it accordingly?

VV i want these to be flat on the wall

[warm torrent]

Not with sub emitters alone
I believe the only way to do it is to use particle collision events
https://docs.unity3d.com/ScriptReference/ParticleCollisionEvent.html
And instantiate the splash particle at the intersection point and pass it the normal of the geometry so it faces away from it

Though consider that the illusion of the effect will break if the splashes can be spawned on curved surfaces or near edges so that a part of them can be seen floating

[round oyster]

Is there any way to make a particle trail circular, without changing the material?

[graceful creek]

Hi guys. I have 0 expierence with VFX graphs, so for my current project I decided and buy a VXF graph pack.. Now, I'm using 1 simple effect in a scene, and the tris count went up from 1.6 million to a Whopping 25.6 million

its a simple portal type effect that loops.

What could be That impactful? What am I looking for?

I'm assuming that it could be some sort of lighting thing, but unsure. If someone could point me in the right direction it would be much appreciated

I'd rather try and learn and understand then just ask the developer of the pack

[opal star]

Check how many particles the effect is using. Each particle is a quad. Quads have two triangles. Do the math

[warm torrent]

VFX graphs can render a lot of geometry for very cheap
Tri count alone is not a good measure for performance

[tender seal]

anyone have an idea, or what i do wrong to create a particle Material?
I change the color but is looks in that color

[warm torrent]

Magenta color means shader error
This happens if there's something wrong with the shader, or if it's incompatible with your render pipeline (or if something else went wrong)

[tender seal]

@warm torrent ya, i missed that i rerendere the URP shader, now it works 😄

[manic scroll]

Hi! I Bought a udemy course from 2018 and the interface is a little different and i cant solve this. He draw a texture in photoshop and created a cylinder in blender. I did the same after that he made a particle system then from renderer he chosed mesh as a mesh he picked the cylinder and as a material he created a material and assigned that texture and its look like this

mine doesnt show the drawed texture

any idea what i did wrong ?

[strong birch]

Can you make a better readable screenshot of the inspector?

[manic scroll]

mine or udemy courses ?

[strong birch]

both

[manic scroll]

this is his

this is mine

i feel like i made something wrong with shader graph but i followed excatly

there is color on the top left

[strong birch]

He has another render mode: horizontal billboard

Does that make any difference?

[manic scroll]

no when i do that effect lose the cylinder shape

did I fail to give texture to material ?

when he give the drawed texture to material his material its look like this

[warm torrent]

@manic scroll Your "Texture 2D Asset" node refers to a specific texture asset on the file system, your MainTexture property is not used at all

You would drag MainTexture property into the node board and connect that to Sample Texture 2D input instead

[manic scroll]

Finally thank you so much!

[warm torrent]

I had to squint a bit to spot that one 😄
Also, your shader graph UI is messed up somehow
It may be helpful to try fix it

[manic scroll]

well i start learning yesterday so i have no idea what is what 😄

[warm torrent]

Just restarting the editor might help, if that won't then perhaps deleting the project's Library folder and letting unity regenerate it
After that I'd consider updating to editor 2021.3.5f1 or just living with the problem and hoping it fixes itself at some point

Good luck either way!

[manic scroll]

Thanks!

[keen dagger]

So I added a particle system, is there any way for me to change the angle it scatters the particles at?

[silver oak]

In Shape you can change the shape, so you can make the Cone wider.

There are also a ton of velocity parameters you can set.

Hey everyone! Running into an interesting VFX graph issue when updating Unity to 2021. In my project, I need to use OpenGLCore as a graphics API, and my VFX graph works in 2020.3.25, but when upgrading to a 2021 version of Unity, none of my VFX particles render out unless I use DirectX as the graphics API. Tried the default VFX graph, but no luck with OpenGLCore.

After searching around forums and docs I couldn't find any specific reason why this is happening, so I'm kinda at a loss.

Thanks for any help!

[fathom flint]

can someone inform me why my particles seem to still go through the floor despite having collision on world mode

a couple of them go on the floor but they dont spread out or anything and most of them just go straight through the ground

the ground in question is a flat plane

[violet sundial]

Hi, I want to ask, I used the particle system for shooting effects, but why is the particle system always active?

Can you help me?

[warm torrent]

@violet sundial settings called "looping" and "play on awake" are probably what you're looking for

[violet sundial]

Thanks, you saved me

But, why when the game starts and I press left click, the particle is destroyed and an error appears

[warm torrent]

Make sure "stop action" is not "destroy"

[violet sundial]

I don't know but after I changed the particle system, the problem was resolved

[velvet seal]

Unity 2020.3.5f1 -> having this weird issue where any extra systems I add into this VFX are either appearing as an alpha clipped black circle at (0,0,0) or not appearing at all regardless of node setup. This is the current setup...

The system on the right is that black particle

It does not seem to adhere to position or colour at all

If I replace the GPUEvent with Spawn(Constant), it works fine

Also this warning keeps coming up despite me not having any of this component...

There was one question. How the unit caches, for example, particles. Let's say I have a prefab with cloud particles. I deliberately play them on the initial scene literally for 1 frame. However, on other scenes I do not use a prefab, but I made Unpack this particle and also lose. Will Unity cache these particles in this case?

Here are my particles:

on the splash stage I play them

there is still a lag on the first play

Is there a way to call a function when a particle dies, similar to the OnDeath function with sub emitters?

[prime dome]

I feel like I am going crazy, it seems like there is no clean legitimate way to properly do particles on a UI canvas in HDRP

The only way I can think of is by having another camera do a Render Texture and then using a Raw Image with that render texture on the canvas, but I can't comprehend how you would properly line up stuff.

Does anyone have any experience with this? I've been beating my head for the past hour trying to think of how this is do-able.

It's so simple in URP too...

[fluid lagoon]

you could use world space or screen space camera canvas and just put the particles between the camera and the UI

[prime dome]

How does that work if the screen space canvas doesnt align with the camera?

https://i.imgur.com/Tszl6cl.png

[fluid lagoon]

screen space camera canvases always alight with the camera

[prime dome]

Oh screen space camera, not overlay

[fluid lagoon]

yes

[prime dome]

Now what if I want the particles rendered over the UI?

Would that just be the rendering layer?

Oh wow I feel like an idiot

I think I can work with this

[pine hinge]

hey dudes if i make an explosion effect with built-in Blender smokes or fires and export it to Unity will it still work the right way?

[prime dome]

Definitely not

[pine hinge]

Ohh alright thank you appreciate it

[prime dome]

I totally forgot the original problem of this

If you do screen space camera canvases they get affected by post processing

So bloom, color grading, etc. all mess with your UI

[prime dome]

Okay so I think I have it all figured out

I created an Amplify Shader and for the rendering pass I set it to "After post-process". I set my image material to this new shader and the issue is seemingly gone

[manic scroll]

Hi! i drawed a textured and put it on a mesh but i only see the side that are looking at me. how can i fix that

[viscid kindle]

I think it should be the shader on the material you've selected, if you're using the standard unity shaders i think it's got an option for double sided or render face or something
Edit: @manic scroll

[manic scroll]

yes that was it i though double sided option would be in particles options

@plucky path in the object hierarchy, click an empty space

Then the particles just freeze

I want them to keep moving

I have a rain particle system, though when I look forward it doesn't look like there's a lot of rain (because the particle system is only above the player). How can I make it look like it's raining a lot, whilst not killing the player's pc

why do they make this map soooooo big? Can't they just zoom in the rooms bcs now I have no idea in which room Im in

can't they just only show this?

[raw osprey]

Did you get it working ?

[mystic mason]

why do my particles only play once even though its looping?

[warm torrent]

"Selection Outline" in gizmo visibility

hmm Ill have a look next time, thanks

I did not

[raw osprey]

Can you show me what you did ?

You want sth like this ghost rider iirc

[normal needle]

Yeah like that

[normal needle]

I deleted it because I was so fed up with it, really it was just multiple particles with flames with different colors

[raw osprey]

Did u use the skull mesh as the emiitter shape ? Its just the fire particle then use the skull as its emitter and play with the rendering queue to make it alwayes behind the skull it should give you that effect or very close to it

[normal needle]

Oh really? I never knew that!

can you show me an example?

[raw osprey]

yes i can give me 10 mins to try it

[normal needle]

ok

[raw osprey]

Just got to my pc anyway in the ps inspector Shape then youy can assign the skull mesh you want to use as the emitter shape and choose from what to emit vertecies or triangles or edges ig in this triangles will be better

[raw osprey]

then everything else will be tweaking the ps itself to give you the best result and feeling for the neck just use another fire ps with box or capsule collider thats small and make it's lifetime short for the rest its the ps that will give the feeling the better the visuals the better the result

[normal needle]

Gotcha ok

thank you

[normal needle]

Would you accept pay to do it for me? Just curious

[raw osprey]

no sorry , what are you struggling with?

No worries, I'm just struggling cause I'm pretty new to this but Its just confusing to me. Wish there was a specific video for this

[lyric kindle]

Hey quick question

I have a nice shader with mask, but it's pretty expensive in terms of resources (I can barely process 100 of it in the same scene, theoretically).

Does the game/unity render objects that aren't in the field of view ?

let's say there are 100 of this shader object in the same scene but i'm only looking at 1 , the other 99 are behind the camera, would the device be rendering the entire 100 (clones) of it or just the ones in the field of view ?

[fluid lagoon]

no, Unity does Frustum Culling by default.

[stable panther]

I made a vfx graph that spawn particle trails, but when it move fast the result became something like this

[outer storm]

IsAlive: contains any live particles, IsPlaying: the playing state. ie pause the system, it will return false. Stop the system, it will return false, even if some particles haven't expired yet. EDIT: I've also just realised the docs for isPlaying are totally wrong. I'll get that updated too!

[outer storm]

Consider using the StopAction feature to track this, though: https://docs.unity3d.com/ScriptReference/ParticleSystem.MainModule-stopAction.html (can setup in inspector too)

[outer storm]

In addition to the locking inspector trick in the provided link, you can also select a system, then modify the "Simulate Layers" option in the Scene View Overlay. Any systems matching the layer will preview regardless of being selected or not. You can also turn off the Selection Outline entirely by using the dropdown arrow on the Gizmos icon in the very top right of the scene view.

hello

I have a project that is using URP, and I'm looking for a good explosion package, I found one that I liked and its free Unity Particle Pack "https://assetstore.unity.com/packages/essentials/tutorial-projects/unity-particle-pack-127325" but it looks like as if it's using the standared shader pipline for some reason

is it possible to convert it to URP ?

I dont know much about VFX and shaders.

[sullen trench]

I had an idea for a game so i made a demo in Python. how could I get this effect in unity2D.

[limpid orbit]

How do I use VFX graph with the default render pipeline? Or is there a way I can create a render pipeline that is able to use the VFX graph without changing anything else in my project at all? I tried upgrading to the universal render pipeline but even after upgrading and converting everything so that it could accommodate the change, all of my materials get messed up and result in the game screen being completely black when played. Luckily I created a backup of the project before making the change. I still need to use the VFX graph though, so how do I do that without breaking my game again?

[fringe forge]

From the Unity documents:

Requirements
Unity 2018.3 or newer. Verified packages start at Unity 2019.3.
A Scriptable Render Pipeline package:
Universal Render Pipeline(2019.3 or newer)
High Definition Render Pipeline (2018.3 or newer. Verified packages start at Unity 2019.3.)

So VFX graph won't work with standard.

is anyone available to help with a gun shell ejection particle transform issue - in a nut shell i've positioned a shell ejection sub emitter particle to spawn at the time a gun fires as it would in reality, however when I turn my character around the shell ejection continues to happen at the same direction as it was initially and ends up spawning on the opposite side of the gun. This is all built without any scripts and there cannot be any used in the project. Any help is greatly appreciated!

[outer storm]

I think there are "ways" to make it work. But Unity's official line is that it's not supported in built-in. Perhaps look on the forums eg https://forum.unity.com/threads/visual-effects-graph-in-built-in-render-pipline.1121155/

Hi guys! Do you know how to sort the rendering order of a visual effect that uses a flipbook?

[granite hinge]

How do I use this module in the Particle System Component

my particles are rendered as Meshes

These meshes have their own material which they use, which is basically just a material with flat white color

It seems like the material of the mesh is being used and the module has no effect in my case

how would I go about making it so that the particles "fade out" over time or loose transparency

[warm torrent]

The colors in particle systems are vertex colors, so the material's shader has to apply those into color and alpha

[granite hinge]

I read something similar on some forumn, but im having a hard time figuring out how to go about doing that

.<

[warm torrent]

Which render pipeline are you using?

[granite hinge]

URP

Tried doing this but doesn't seem to be working

[warm torrent]

There's particle shaders in Universal Render Pipeline/Particles/ category if you can do with just lit, simple lit and unlit

Your shader graph implementation looks okay but the shader needs to be set to type transparent in graph settings to be able to use transparency

[granite hinge]

hmm lemme see

okay it... kind of works..?

It does fade out

but occassionaly

You can see here, the water sort of "cuts off" or hides some of the particles

its a bit hard to see

Here you can see

I think I have an rough idea of what is happenign

so the water is basically just the same prefab instantiated in a grid

to make it look big

And it looks like at some of the edges of each water plane mesh, the render order gets a bit iffy????

im not sure

This problem only occurs with transparency enabled

[warm torrent]

Transparent materials are sorted by their origin, unless the render queue is changed

That's a separate problem from particles not fading though, take it one at a time

[granite hinge]

The particles have started fading, the render queue thing is remainign now i htink

ill try to find out how to adjust the render queueu

[fading goblet]

I was just wondering, Is there away I can make a player see through a particle and make the particle still effect the surrounding in the same time?

[shadow scarab]

so when i try to use collision module for particles, it's alright but when i add a mesh to the planes transform list, instead of working normally the particles just go under the plane(like the spawn point goes under the plane, not the gameobject). what can this be?

here's a sc

collision modules settings

it works with another flat plane i created, though

nvm i just needed to set it to world mode instead

[warm torrent]

"planes" does not refer to mesh planes, but rather mathematical planes which are always flat and infinite in size, projected from the transform of the object in the list

(actually I'm not sure about the size part, but should be quick enough to figure out)

It is bad in game mod.

[warm torrent]

If you pause play mode when the effect is visible and click on them, do they show up as the same particle system or two separate ones?

Problem solved. It was two scenes in hierarchy. In one of them was old version of effect. When I start game mode it started two scenes with new and bad versions. I removed old scene.

Hello I am learning Unity from the official Unity web page i take the Junior programmer pathway and I am at the lesson 3.4 which is about particles and I am at the point where when you collide with the obstacle there should be particle animation played but it doesent work and I have no idea why

[shadow scarab]

in the argument, you cant get Collision collision other

you need to write:

Collision other

2 Collision's will return an error

[graceful imp]

This doesent work in my script i had Collision collision without the other

[shadow scarab]

ok

did you add the tags?

like you might have created the tags and forgot to select in the gameobject inspector

also it is in fact case sensitive

you can omit the oncollisionenter private btw, by default it's private if u dont write anything

[graceful imp]

I had

[shadow scarab]

also i find it weird that there are 3 "." before explosionParticle.Play()

error indication in ide?

[graceful imp]

This is photo from the page it is shortened https://gdl.space/zidiriweza.cpp her is my real code

[shadow scarab]

what error do you get?

or are you not getting any errors?

[graceful imp]

None

[shadow scarab]

i suppose you know for oncollisionenter to trigger, either body MUST have a rigidbody component?

it is ideal if the rigidbody component is on the "moving" body

make sure your objects are not set to static (top right in inspector)

again, please double check tag spelling, case sensitivity and tag assignment

[graceful imp]

Thanks

Hey I recently turned post processing/bloom back on, and this effect is little bit of an eye sore.... any iea how to get it to stop flashing like that?

https://gfycat.com/NastyBigheartedAlleycat

[frigid matrix]

I’m not 100% sure if particles work this way, but perhaps the particle’s layer isn’t in front of the background. Maybe the background and the particle sprites are on the same layer. Try pushing the BG back one. I could be way off though lol

[atomic magnet]

no thats not it, thats easy to check, and I did double check

they are on seperate layers and not having any conflicts

ooh that did help me fix it though!

its cause this is actually 3 particles systems layered on top of eachother

and they are all on the same layer, which didnt matter before post processing

but the sorting bungling is whats causing the flashing

thanks~

[harsh bridge]

Does anyone know if it's possible with the normal particle renderer UI to create a series of particles in a line but in order? I was trying to make a lightning bolt using ribbon with randomly displaced particles along an edge but they aren't arranged in any logical order, so it just makes a mess instead of a nice zigzag. I know this is really trivial to do using scripting (that is what I ended up doing) but I'm curious if there's a method to do it with the GUI, seems like a pretty normal thing to want to do

I tried using pingpong mode and making them scan across the object really fast but it still looks like the lightning bolt is progressing rather than just appearing all at once.

I dont have a screenshot right now but this is what I mean, left is what it produces, right is what I was trying to do:

[prime dome]

After adding particles like how they showed up in this video, I'm noticing a considerable drop in framerate whenever I spawn this explosion effect.

Same drop.

[proper raptor]

Might be your computer or just the preview? Have you tried building the game and trying?

[harsh bridge]

Use bursts?

[sweet tendon]

Can you only have bursts?

[harsh bridge]

Do bursts, set cycles to some large amount and interval to a small value

It should be pretty much identical to how it looks when you do rate over time

Oh and 1 particle at a time

for the burst

[sweet tendon]

Yeah 😂

Ok I'll try

I wasn't really able to achieve it with burst but it was probably me

I'll try again

[harsh bridge]

I believe it normally only spawns 1 particle at a time anyways - it should be pretty close. You might have to do some math to figure out the correct amount/interval for your period

[prime dome]

I've not tried building the game yet. Let's see...

[prime dome]

Ok, so it seems to just be the preview.

Also, it seems the mouse sensitivity is much higher on my player camera than it was in the preview, but that's a problem for another time.

[dreamy pelican]

maybe someone here knows how to do that properly. i have a particle system (for the shooting arrows) using mesh rendering and a sub system (for the stuck arrows) that gets activated if the main one dies on collision. my problem is that the arrows of the sub system dont have the same direction/rotation of the main systems arrows. i tried playing with inherited attributes and different render alignments but i cant seem to get it to work.

Yep that's what I thought, good luck with your game!

[clear spruce]

Use vfx graph if you dont already

i use this in vrc so that wouldnt be available to me x.x

since (and i think this is the right lingo) vrc uses a set render pipeline so vfx graph doesnt work for it and it has to be a fixed set shader

[topaz juniper]

I am attempting to use the Ribbon feature in a Particle System to create an effect. I want the scale to shrink over time and for some reason I am getting the jagged look in the image before. Does anyone have any idea what might be causing this or how I can solve it?

Edit: I am using a shader/material rather than a texture.

Seems like a vertices issue, I don't see a way to increase the number of vertices in unity, though.

[warm torrent]

It happens due to fundamental limitations of rendering skewed geometry
The only practical fix is to never scale the trail, instead use a texture which tapers

[topaz juniper]

That's unfortunate, thank you.

[outer storm]

The only way I can think of, is to make a Mesh, and emit from the vertices of the mesh (You can do this in order by setting the Mode under the Type: Vertex option. You'd probably still need to make the Mesh via script though, to guarantee the mesh vertices were in the order you wanted. You could also use Randomize Position a bit to make sure you didn't get the exact same lightning shape each time, if you wanted.

[outer storm]

If your particles always have the same lifetime, you could set up a burst and figure out the maths yourself. Otherwise, I think you'd need scripting. You could set the Stop Action to Callback to start the delay timer, then call Play() again when the timer had elapsed. It would be a pretty simple script.

[reef plover]

im trying to make a smoke effect using a texture set to the additive/soft shader, but whenever I make the color more gray instead of white, it makes it more transparent and doesnt change the color

anyone know why this is?

[warm torrent]

That's how additive rendering works
Black is totally invisible, white is totally visible

[harsh bridge]

That makes a lot of sense actually. I didn't know that meshes preserved vertex order when emiting!

[cosmic oyster]

Hello, the 'Graph Inspector' is missing from my VFX graph and I am not sure why, does anyone know why this might be the case? (2019.3.11f1)

[outer storm]

It's a semi-recent addition. If you make a mesh using lines/line strip, you can also emit along the edges over time. That's no good for your instant lightning effect though, as you want it to happen over 0 time, from the sounds of it. So vertices + ribbons seems like a good idea (although, thinking about it some more, we connect the ribbons based on particle age, so i'm not sure if the ribbon connection system will get confused by all the particles with the same emission time.) A different idea would be to revert back to the time-based approach you had, but, to get the "instant" effect, call ParticleSystem.Simulate from script with the time it takes for the emission to happen over the length of the lightning bolt. Just rememberthat calling simulate pauses the effect after it completes, so call Play() again after Simulate() to make it carry on playing normally.

[harsh bridge]

Hmm

Must test

I didn't think it was by particle age! That's odd

[frank crown]

has anybody ever had that issue with the position (skinned mesh) node where particles spawn on the skinned mesh, but offset vertically by about 1m? Can't figure out what's causing it

[civic bolt]

So I recently found out about ParticleSystem.GetPlaybackState() which sounds useful for me as I want to potentially save the state of a ParticleSystem as part of my game's overall save state: https://docs.unity3d.com/ScriptReference/ParticleSystem.GetPlaybackState.html

However, I cannot make use of it in this way (saving it to disk to be restored later upon load) because the struct isn't marked as Serializable, despite only consisting of primitives or structs of primitives. Why would Unity not mark this as Serializable? Is there a way I can work around this?

[outer storm]

The use case we initially covered with this was for users to save "keyframes" of their particle system state, in order to be able to restore a particle system to a previous state. Useful for fast rewind features, for example. However we only thought about users doing this in game, and not about a case like you have, where you want to save this snapshot to disk. To get a full snapshot, you also need GetParticles, but the Particle struct doesn't look like it's marked as Serializable either. And also GetTrails(), if you want to save trail state. All in all, it seems like we could make these Serializable quite easily, but, getting that change to whatever version you use would of course take a long time. I don't know if there are other workarounds..

[civic bolt]

It would be nice if they were marked as Serializable (this goes for any trivially serializable object in Unity source, I've had to make custom Serializable wrappers for stuff like Quaternions and Colors to work w/ my save system), but in the meantime I've found a workaround that's simpler and seems to work fine: just saving the random seed and time of the ParticleSystem and restoring state using the ParticleSystem.Simulate(time) method.

I appreciate the response though, please consider it for the future!
