archived-lighting

[delicate sonnet]

looks like this beforehand, other objects in the scene are fine as well

[deft fiber]

I would check "texel validity" as the first thing

Maybe some of those other modes too if they reveal errors

[delicate sonnet]

this definitely looks like something is going wrong there

this also caught my eye, Baked Lightmap Culling, Ill look into these further

does this indicate that my lightmap needs to be higher resolution? or just different settings for specific meshes?

[deft fiber]

@delicate sonnet invalid texels from my understanding are caused by invisible backfaces near the errors
https://forum.unity.com/threads/faq-blocky-artifacts-appear-when-i-bake-a-scene-how-can-i-fix-them.951444/ here's info about that specific issue

Lightmap resolution only needs to be changed if lighting is too blocky or blurry in some places, or if it's wildly higher resolution in others
But look into the invalidity first, that seems to be the more likely cause for blockiness

[delicate sonnet]

thanks so much for the help :) I will try that out

[hidden edge]

Hey can anyone help me with hdrp lights? I can only get the point and spot light to emit light with a very high intensity and i dont think this is the intended way of using them.

[tight lynx]

im new to all the emission and lighting stuff and have no idea why the scene keeps looking like wet cardboard when i bake the lights, this lamp here has a bulb thats has an emissive material and you can see the bottom of the lamp looks disgusting and the surroundings just look really low quality, i just can't quite get the lighting to work correctly

[jaunty briar]

This is how I did it. I just made a texture used only during baking for the lampshade where the entire inside facing parts of the lampshade was emissive. Then after the bake, I switched back to the default texture.
Also, make sure to bump up the intensity of the HDR color picker in the emission slot to get the result you want

[deft fiber]

Light from emissive materials tends to be weak and noisy, compared to directional or point lights due to the nature of raycasting, so you may need to increase intensity to make up for it
Also, I don't think unity's lightmapper does transmission at all, so the lampshade will block 100% of the light which is not how lampshades should work
You can fake it by making the lampshade itself emissive

[jaunty briar]

"You can fake it by making the lampshade itself emissive" - Good idea actually. I should make the outside less intense so I get a softer transition on the wall. Nice one 🙂
(couldn't spell for shit)

[deft fiber]

Using a bit of both techniques is good, but instead of relying on just emission, you might want to use a point light which doesn't cast shadows from the lampshade

[jaunty briar]

My lampshade (real life) actually casts that shadow. Just slightly less intense.

This because it's quite black and not very translucent

[deft fiber]

You'd still see that shadow if using both point light and emissive bulb
But if the shade itself is emissive, the point light may look okay with the shade's shadow enabled
Both are good options ^^

[tight lynx]

the emissive lampshade is quite smart lol, good idea, ive been fiddling around for a while and just plopped in a point light, it definitely looks a lot better though its still kinda scuffed

my aim is for the room itself to be pretty dark and a couple light sources emit some smooth light

[jaunty briar]

Almost looks like you don't have enough bounces for indirect lighting

[tight lynx]

where would i find this option?

[jaunty briar]

What baker are you using btw? Progressive?

[tight lynx]

progressive GPU

these are my settings

[tight lynx]

damn imma try that now and see how it is

[jaunty briar]

Mine are quite high. But they do recommend quite high values for interior scenes.

[tight lynx]

no clue if this is gonna kill my pc while i bake it

i just increased the bounces for now, its baking

[jaunty briar]

Haha, you'll find out. I only have a 1070

[tight lynx]

i shoulda let my friend sort out the lighting since he has a far better gpu than me

changing bounces resulted in the same thing, is there a way to make the entire room darker? i have environment lighting source set to color which is black

[jaunty briar]

Are you using reflection probes at all?

[tight lynx]

im not sure what probes do at all

when i put one in it sort of looks like a cube of light

[jaunty briar]

Okay. Well, they're for reflective materials. So that your materials know what to reflect basically. But that's not it then if you don't have one there

You can play around with these at the bottom of your Lighting settings

"Indirect Intensity" that is. Lower it

[tight lynx]

to 0? mine is currently 1

[jaunty briar]

I wouldn't go to zero. So, indirect lighting is what bounced lighting creates. Think of light coming from a bulb, it hits a surface, that's direct lighting. But then it bounces off that surface onto another and lights that up slightly, that's bounce 1. etc

So, 0 means only the first surface hit will get any light. Not very realistic if that's what you're going for. Better to just lower the intensity of your emission really

Unless you're getting into post processing :p

[tight lynx]

im probably gonna lose my sanity with post processing lol, ive been sitting fiddling with light/emissions pretty much all day today

ill have a look at the emission intensity

[deft fiber]

Worth making sure you're using HDR for this scene
It's difficult to create convincing low-light settings without it

[tight lynx]

i know the emissive source is definitely HDR

not sure if anything else needs to be

[deft fiber]

HDR needs to be enabled in the renderer's quality settings, and then you need some post processing to control it

Tonemapping primarily, post exposure sometimes

But that's more of an overlapping topic with lighting

[tight lynx]

is this a prebuilt thing in unity or do i need to download these things and import

[deft fiber]

I don't recall at present
Might've been one of the official packages, depending on rendering pipeline

You can still improve that scene without delving into HDR, so it's tiny fork in the road

[jaunty briar]

If it's the default render pipeline then it's under "Graphics" in Edit > Project Settings.

I think HDR is enabled by default if you're working for PC builds?

[tight lynx]

yeah HDR is enabled on the different graphics tiers

defaulted

[jaunty briar]

Yea

[deft fiber]

That's good

[tight lynx]

honestly as long as it doesnt look like wet cardboard, i cant complain

[deft fiber]

Linear color space should be enabled too

[tight lynx]

yeah i enabled that since every guide ive watched had it lol

i appreciate the help

[deft fiber]

Your scene does look rather dull compared to what I would expect with default settings

I usually turn them down a bunch and it still gives pretty good results

[tight lynx]

was a hell of a lot worse before, wish i had screenshots saved

it looked like someone spilled water on a painting and everything turned nasty

[karmic wing]

when i add 2 reflection probes unity editor just freeze, any idea why this happens and how to solve it?

like i can still go into unity and it shows the mouse icon when i drag but it doesn't do anything

it seems to happen when there is 2 different reflection probes enabled at the same time

its like stuck saying "1/2 reflection probes | 1 jobs"

and its stuck at nearly end

[deft fiber]

@karmic wing Please don't crosspost
Hard to guess, but it's most likely a bug in Unity with your specific OS/hardware

[karmic wing]

sorry for crossposting i just didn't know where to post this issue, i resolved it by somehow saving the project while the job thing finished then reloaded and it worked, i don't really know why was it freezing though

[vagrant flume]

Anyone know why a scene that's just duplicated would have completely different baked lighting results?

[pulsar aspen]

I've got a skybox responsible for a transition from light to dark. by setting Exposure.
Once 0 exposure is achieved I have what is essentially a black screen.
My problem is this only happens in the editor- in game my model remains somewhat lit up from the previous exposure- decreased but not entirely, the color and some brightness remains. Any ideas?

I've turned off HDR, made sure editor/player quality settings were the same.

[timber lichen]

hey guys, how do I make the edge of this light blurry?

right here

[deft fiber]

Soft shadows are not a feature that normally exists in unity

Assuming what I'm looking at is the edge of the shadow cast by the rocket

You can get around that limitation by using a spotlight that has distance between its inner and outer cone

The rocket can be placed on its own layer and excluded from the light's layermask to stop it from casting the sharp shadows

[gloomy cloak]

when i enter the next scene the lighting is completely pitch black. this doesn't happen if i launch the scene directly.

[deft fiber]

Are you loading the scene additively? Have you generated the lighting in that scene?

[gloomy cloak]

additively?

also the lighting is just a regular directional light

it's completely normal when i launch it directly

[deft fiber]

@gloomy cloak The lighting data for the scene fails to load for one reason or other
It could be that the directional light type is "baked" but lighting is not generated, or it's some editor bug

[gloomy cloak]

it's realtime

[deft fiber]

If you go into scene view after level load and it's dark, are you able to change the directional light's settings?

[deft fiber]

Enable lighting in the scene view to see if the changes have any impact

[gloomy cloak]

how do i do that

[deft fiber]

this lamp icon here

[gloomy cloak]

uh

[deft fiber]

Next I might try adding point lights to see if the scene reacts to light sources at all
But before that you should generate lighting as I first suggested, just to rule out messed up lighting data in the scene

[gloomy cloak]

i added a point light and it did nothing

and idk how to generate lighting

okay i managed to fix everything

also how can i get rid of this brown effect?

[deft fiber]

What'd you figure out?
I have no idea what that "brown effect" is just by looking at it

[gloomy cloak]

i got the light to somewhat work

https://media.discordapp.net/attachments/497873729578336276/880121279632539758/unknown.png?width=960&height=520

but it's still really dark

by brown effect i mean the brown colouring that's on the ceiling

[deft fiber]

That doesn't help me understand at all

[gloomy cloak]

this https://media.discordapp.net/attachments/497873729578336276/880120689875648573/unknown.png?width=960&height=520

[deft fiber]

That... doesn't help me understand at all

[gloomy cloak]

the brown colouring on the ceiling. i don't want it

[deft fiber]

I figured that much

[gloomy cloak]

do you know how to get rid of it?

[deft fiber]

I have no idea what it is because I have no information to go on

[pulsar aspen]

tbf if he knew I doubt he would be here asking.. comes off as a little patronizing

Post your lighting tab settings, if you can't find it look for the top tabs Window > Rendering > Lighting

@gloomy cloak

From what I see in the last pic looks to me like you've got a very high intensity (or post like bloom) and not a very big radius

the brown could be the model's material.. is the color tinted brown? is there a brown texture.. and last thing I can think of, could be a lightmapping issue

I'm going to guess it's the material though

[deft fiber]

Yes, I am little snide when someone comes in assuming we can solve their problems without any clues whatsoever

[versed summit]

Hey guys, i have little problem.
Every surface that is flat plane is weirdly shaded like this.

or the trees

all leaves share same material and yet half of them is white

[compact pumice]

@versed summit Has posting in this chat gotten you any help? Did anyone reply to you in DM's or something or is it seemingly dead...

[timber lichen]

in my 2d game there is a spot of darkness where there is light and i have no idea why its there can someone help

[half ore]

Hi! I'm pretty new to Unity and I'm curious if there's a way to accomplish this:

I have a separate interior and exterior, with two cameras and a draw order, to give the illusion that the interior is moving (simulated spaceship). The downside is that lighting doesn't propagate from the "exterior" camera to the "interior" 3d models, because the interior isn't actually moving.

What I want to know is if there's a way to configure my interior lighting.. I guess to behave as if it's in both locations?

[covert stirrup]

What kind shader are you using @versed summit? That looks like smoothness to me

[deft fiber]

Reny's materials showing through themselves is a z sorting issue, caused by using transparency
Fix is using opaque material with alpha clipping
Why they also have a glossy kind of glare, hard to guess
Probably something specific to the shader, normals or something else in the asset

[deft fiber]

Please try to avoid crossposting
What lights are meant to affect the darkened area? Are the Z values and orders in layer correct?

[versed summit]

not really, until today it was pretty dead

[timber lichen]

i turned all light emmiting objects off and nothin works

[deft fiber]

So, the problem is that the sprites are ignoring the lights in that location, or vice versa?

I would isolate the problematic lights and sprites into a new scene, add new sprites and lights next to them, see if the new stuff works and compare

[timber lichen]

but there are no problematic sprites or lights

[deft fiber]

I must have misunderstood what the problem is

[timber lichen]

theres a pentagon of light for no reason in this single spot i tried disableing everything and it wont go away

[deft fiber]

Lights hardly exist for no reason
Most likely a parametric or freeform light you've lost in the hierarchy

[timber lichen]

how would i find it?

[misty ice]

hello! im currently trying to make dust particles only visible in light for my flashlight but i cannot find any google searches for it, well i did find one but the links don't work anymore

[daring oar]

@misty ice hey if your game is 2d you may be able to make a sprite mask on your flashlight and set the particles system to only be visible within mask

[misty ice]

no, its 3d

[daring oar]

ok it looks like you may need to use a shader for masking in 3d look up 3d masking on youtube you should be able to find something

[iron fern]

Hi guys.
I'm using URP and I have a very simple but very strange problem.
I posted it on the forums, if you wanna check that.
https://forum.unity.com/threads/ambient-light-skybox-mode-gets-darker-after-loading-a-scene-in-play-mode.1162859/

[vagrant tendon]

hello guys

im having an issue with lights

i have 6 lights on this gate, but you can see only 2 of them works, why ?

[deft fiber]

There's a limited number of realtime pixel lights that can affect any one object when using forward rendering
Solutions include increasing the light limit in quality settings
Splitting the object into smaller pieces so less light per piece
Switching from realtime lights to baked lightmaps
or switching from forward rendering to deferred rendering if your rendering pipeline supports it

[vagrant tendon]

i will need to generate light for baked right?

[timber lichen]

how can i stop light from shining through certain walls (mainly, i don't want it hitting the walls in the tunnel) with probuilder maps?

[deft fiber]

Yes
It's an entirely different way to handle the scene's lighting with its own pros and cons

[deft fiber]

I'm not familiar with probuilder specifically, but light will pass through backfaces of meshes normally

You can change that behaviour by making the shadow casting type "two sided" so it'll block light from both sides

That's an easy solution, but more expensive computationally

What also works is making a box or other type of external walls around the room, and setting that to "shadows only"

Or in case your scene is entirely indoors, you could disable the sun entirely

[timber lichen]

two sided seems to work, but has these weird light lines

i may just go with a point light as that seems to behave much better

[deft fiber]

This is light leaking through edges between polygons, happens in way too many situations
I'm not sure if there's any one good fix for it
Shadow settings can balloon up shadows to cover up the seams, but that has side effects
Using the box/ exterior wall shadow mesh method allows you to minimize the seams

[timber lichen]

hey, thanks for the help. i decided on setting up HDRP and using point lights, they cast v nice shadows as well as illuminating the room in a way that looks realistic

[lucid mesa]

I added a volume script to this object and it’s glowing nicely but when I move the camera away from the object, the glow disappears. The mode is on local right now because when I had it on global, the whole world was glowing. I would like the stick to glow the whole time. Help would be appreciated 🙂

[toxic solar]

is it possible to make lighting baking from CPU to GPU instead? my 1050ti doing basically nothing while my CPU is almost thermal throttling

[deft fiber]

Yes, change Lightmapper to Progressive GPU from CPU

[toxic solar]

when I do that it gets stuck at "preparing bake"

[deft fiber]

It should work without a hitch just by changing that one setting

Try it in a fresh scene to see if it's a problem with existing lighting data

Restart unity editor

Maybe update GPU drivers

[toxic solar]

it does say preview though (2019.4)

that could be it

[wet shore]

Hey, I've been trying to light a room but I'm struggling to emulate the lighting setup I had in Blender

This was the test render I made in Blender. But when I ported it over to Unity...

Obviously a game engine can't outperform a ray tracing one, but there's no shadows? It's weird :0

[timber lichen]

use URP it adds shadows and everything
(youtube videos on how to setup it are easily accesable)

[wet shore]

Cool! I'll look into that quick

Thank you so much! I haven't got it all set up yet, but this is the kind of stuff I wouldn't know how to look up because I'm a Blend head @timber lichen

[timber lichen]

no problem if you need anything then try to ask me im most likely online

[deft fiber]

@wet shore You could bake the lighting and you'll get ray traced global illumination, not unlike the cycles render, but it'll be static

[wet shore]

I tried doing that, but no shadows appeared

[deft fiber]

It'll only affect static objects

[wet shore]

I set them all to static

[deft fiber]

Lights are of type baked or mixed?

URP and built-in render pipeline both have realtime shadows for point and spotlights, but they won't be at all like the soft ones you get in blender

[wet shore]

Baked

The problem is I have yet to see any shadows

No my lights aren't working since I activated URP

[deft fiber]

Something's wrong, obviously

[wet shore]

I converted the materials, do I need to convert the lights too?

[deft fiber]

I don't think so

also you don't need URP for either realtime or baked shadows

Though it is often nicer to use

[wet shore]

I'm just confused, should I send you the file?

[deft fiber]

Try looking at some tutorial or guide for setting up realtime or baked lights first

[wet shore]

AHHH what's happening

I looked at tutorials, I set everything up the way they had it

I've never had shadows

[deft fiber]

Prefarably in an empty scene/project to make sure you get everything right

[wet shore]

Alright, I guess if I gotta do it I gotta do it

[deft fiber]

In this image the baking is in progress

[wet shore]

There goes all of my progress lol

[deft fiber]

It's not finished so it won't look right

[wet shore]

It shouldn't be that dark from the getgo, there's a ceiling light :(

[deft fiber]

The point is to familiarize yourself with the lighting system
You can return to your scene then

[deft fiber]

It will look messed up while the lighting is generating

[wet shore]

I had this problem before URP though too

The light in the center of the room isn't illuminating anything

When it does, there are no shadows

[deft fiber]

It's not a "problem" if it's because the generation is unfinished

[wet shore]

The generation has finished multiple times and I still didn't get shadows

This was before URP tho

It says it has 1 and a half minutes left and I think it's going to remain mostly the same

Perhaps I should cheat and just bake every texture in Blender 😆

[deft fiber]

The baking doesn't look progressively better as it goes
It looks messed up right up until the second it's finished

[timber lichen]

how do i make auto exposure so when the player steps into a bright area from a dark area it looks like the camera is adjusting to the light like your eyes would when you go into a bright area from a dark one?
(kinda like some minecraft shaders)

[wet shore]

Got it :3

[deft fiber]

Practice more with the lighting system, you're clearly missing something

In your editor version URP doesn't support realtime shadows for point lights, so that won't help you there

What you want to do is doable without URP whether realtime or baked

[deft fiber]

which rendering pipeline?

[wet shore]

Still wacky :0

[timber lichen]

2d URP

[wet shore]

Unironically considering just baking the whole thing

[deft fiber]

I recommend using local volumes to blend from one post processing profile to another

[wet shore]

Can I fake a shadow texture if every material in the map is Emissive?

[timber lichen]

alright lemme see if i can figure this out

[wet shore]

That could be the solution. The lights would look perfect

[deft fiber]

That's your choice, but I don't know why you'd go through the trouble of putting the scene into Unity and then do workarounds instead of using its features

[timber lichen]

have you added a shadow caster to the objects that you want a shadow on?

[wet shore]

How do you do that?

Right now my big problem is that the light in the center of the room just isn't doing anything

[deft fiber]

Shadow casters are for 2D lights

[wet shore]

Also, when I make some changes it makes me wait 3 minutes to continue working

Buster works a lot in 2D I guess :P

[deft fiber]

My suggestion is that you disable "auto generate" lighting and only generate when necessary
Also try Progressive GPU baking if your GPU is decent
GPU baking is generally orders of magnitude faster than CPU baking
Thirdly, try to get a grasp of lighting's basics in a very simple scene with only primitive shapes so you don't waste bake time with complexity

[wet shore]

I have a 3090

Alright, I'll do some experimenting

[deft fiber]

<@&502884371011731486>

[deft fiber]

With that I expect your bake times to go from minutes to seconds ^^

[wet shore]

Hasn't lol

And also no clue what the heck this is lol

[deft fiber]

Tutorials, tests and practice until you do have a clue

I wasn't doing everything right the first or the second time either

[wet shore]

Alright, so I decided to start with a new project

Already I'm getting a better result by using URP

But the volumetrics are way too high so there's a lot of fog

I fixed it by scaling it down lmao

Nvm scaling it was a bad idea

@timber lichen How do I lower the volume?

Also, how do I move my view to the camera's view without pressing the play button?

[timber lichen]

uuuh to move the camera you go to the game tab and go to the camera object then you move it by dragging the X Y and Z values in he inspect window

[timber lichen]

and what volume?

[wet shore]

The thick fog

This is when I move closer

[timber lichen]

hmm i dont know that much about 3d URP but i think you need a global volume

[wet shore]

Oh. So you don't know how I lower it lol

[timber lichen]

noot really

sorry

[wet shore]

oof oki lol

thx tho :)

@deft fiber How do I move into the camera view :0

[iron crow]

How do y'all do Interior Lighting without creating "Bright Spots"

I need to use Real-time lighting

and a spot light doesn't reach the roof

[modest flower]

Lighting tab (the one you open when you bake lighting) under environments (top of the window, middle of the 3 buttons) ? If you havent added any volumes for fog that is

[wet shore]

I still can't get my scene to work

After trying what people said it looks worse lol

There are shadows now, but it's only coming from outside

[modest flower]

you had something that didn't look half bad earlier 🤔

[modest flower]

are your lights all realtime?

[deft fiber]

All objects in your scene should be of reasonable size comparing to the unit grid

One unit corresponding to one metre

Lighting among other things isn't going to work right if the character is scyscraper-sized, for example

[deft fiber]

Camera view? If you're asking how to get to the game window I think it's going to help to look at some basic unity tutorials

this program isn't something you learn by fumbling around

[wet shore]

Actually, that's exactly what I did lol

I fumbled around and figured it out lol

I come from 3DS, Maya, and Blender. So this whole thing is different for me

[deft fiber]

That explains why you're getting stuck all the time and having to ask here
It's not worth it

[wet shore]

I'm used to lights not sucking lmao

Game engine lights are going to change as Ray Tracing picks up

[deft fiber]

You can use ray tracing in Unity

The realtime sort

But I guarantee you aren't going to find that option or get it working without a step by step guide

There's very few things in this engine that are self explanatory

[brazen pecan]

how do I make light interact with only certain sprite?

[deft fiber]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@7.1/manual/2DLightProperties.html#target-sorting-layers
Target Sorting Layers should be able to do that

I think by default 2D lights only illuminate sprites that are under them in sorting order

[olive iris]

use another lighting approach

[brazen pecan]

how can I improve lighting ?(this is so bad )

[deft fiber]

@brazen pecan Please do not crosspost

Examine your goals, how do you want it to be better
Find references and imitate them

[iron crow]

That's extremely vague and means nothing on its own...

[olive iris]

You are right. Since it comes down to understanding lighting and not really a technical thing. You might find the answers here https://www.youtube.com/playlist?list=PL0N1q3x8o-9zzYckCwPNEm7LQQG7xGGlQ

[deft fiber]

Well, the first kind of obvious answer is to make the ceiling darker or less reflective

Another thing you can do is to use a spotlight combined with a smaller radius point light, to get the best of both

But adding more realtime lights tends to have some drawbacks, and it really depends on what kind of light fixture it's supposed to be to make it look right

Right now there's no lamp or fixture so it's hard to guess

Also, using a linear color space and tonemapping is very useful for evening out overly bright and dark areas

Though I think linear color space is enabled by default

There's post processing effects besides tonemapping that can help that also

I would pursue all three approaches

[modest flower]

i was going to suggest this, but i wasn't sure if two realtime lights right next to each other like that would have been a good idea

[brazen pecan]

well I want to make it kinda cozy ,how would you approach that ?

[deft fiber]

It's not totally bad, especially if the ranges are kept as low as they reasonably can be, but more lights will always creep up the pixel light limit per object in forward rendering
In deferred rendering there's no concern

[modest flower]

ah, i see i see

[deft fiber]

I think it looks pretty cozy already, but nothing says cozy like a soft bloom post processing effect

[brazen pecan]

ok

i think its much better now

[ionic ore]

Hi everyone, i need some suggestion about a problem with lightmaps: what could case those error on lightmaps? Uvs are good, no ovelapping.. thanks!

[mortal cosmos]

this is what the game looks like normal

and this is when i switch to it from another scene

way too dark

[deft fiber]

Check texel validity view to see if that reveals something

Seems that visual artifacts on the lightmap are often because of nearby backfaces

[ionic ore]

Thanks, it's seem alright..

[whole wedge]

in urp2D
2D lights are super wonky for me
a global light with no targeting sorting layer will light up everything
the same with a point light

how do 2d lights and sorting layers interact?

[timber lichen]

if a object like the player is set to the default layer then set the light targeting layer to default the light will only effect the player and any/all objects set to default

[whole wedge]

but I've found it to function the exact opposite

I will send screenshots when I'm at computer

[whole wedge]

target sorting layers, none

but when disabled

[whole wedge]

why does this light up all sorting layers even when targeted is set to none?

[whole wedge]

how would i apply a global light to the world, then not apply it to a certain sprite, which is only affected by one light that i specify

[timber lichen]

i dont know right now sorry im tired out from coding ill try to get back to you tomarrow

[whole wedge]

okk

[wet shore]

Hey, I've gotten some good lighting going but I can't seem to get Bloom to work. I looked up several tutorials on how to add Bloom using Post-processing layers, but nothing has worked!

My file had bloom at the way beginning because I started using the default URP project file. But halfway through I deleted the layer that was making the bloom. Before I did, the Bloom wasn't showing anyway

@timber lichen @deft fiber Do either of you know if maybe this could be some sort of layering issue? Maybe some other settings are holding me back? :(

[timber lichen]

its in the global volume where you get the bloom

[wet shore]

Global volume?

I got it using Post-Processing Volume?

I honestly don't know what any of this means. In Blender you tick a box and bloom just appears automatically

[timber lichen]

global volume

use global volume

[wet shore]

Where's that?

[timber lichen]

in the hierarchy

[wet shore]

:(

I'm an idiot, I have no idea which one

Okay, so I did that

And it's still not working

I have no idea what I'm doing wrong :(

[timber lichen]

Me neither dude

[whole wedge]

how would i make a sprite that only lights up by a certain light?

but doesnt by global lighting

i have the sprite and normal map set, but i just cant figure out how to get it to stay invisble, yet only be revealed by the light source when it is made

and how to have that light source only apply to that sprite

[deft fiber]

There's instructions for each RP in pinned posts of #💥┃post-processing

I can't guess which step is missing

Speaking of blender, did you ever try to activate bloom in cycles, without instructions?

[deft fiber]

https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@7.1/manual/2DLightProperties.html#target-sorting-layers 2D light can be applied selectively with the Target Sorting Layers property

Aside from that I think they affect sprites that are below them in sorting order

[gleaming surge]

Has anyone used MK Glow to make objects glow? I'm having a bit of trouble, and there isn't a lot of info online.

Also I have this in my console:
Reduced additional punctual light shadows resolution by 4 to make 63 shadow maps fit in the 4096x4096 shadow atlas. To avoid this, increase shadow atlas size, decrease big shadow resolutions, or reduce the number of shadow maps active in the same frame
like a 1000 times. what's the quickest way to fix this? I've tried doing each of the things it says individually.

[floral parcel]

Using HDRP (and saw the same with URP) I am getting light bleeding through the edges of walls:

any way of fixing this?

[deft fiber]

Are the walls really thin? I guess the simplest way would be to give them some thickness

[tame cipher]

Helllo guys, i have a litle problem with spot lights, the spot is small, like a flashlight, but it is illuminating the entire wall

this is the normal behaviour

but i got this depending on distance and other lights

is like it's lighting up the whole wall and is only a spot light

[slim flame]

Why do I get these weird bands with soft shadows? There is nothing between this object and the light source.

[deft fiber]

might be "shadow acne"
https://docs.unity3d.com/Manual/ShadowPerformance.html

[slim flame]

Yup. Thanks! I'm a programmer, all of this lighting and shader stuff is foreign to me.

[keen compass]

Hrm. Well, I have a dumb idea

Since my game uses a sorta ‘swapping between two worlds’ mechanic that enables and disables certain gameobjects in the scene, I’m wondering

Should I use real-time lighting for this or baking?

[gleaming surge]

What's the best way to shine a light from inside an object?

I've been messing around with double sided shaders, reversed normals, translucency and sub-surface scattering but no combination (plus unchecking cast shadows and receive shadows) is allowing me to use a light inside an object.

[fervent tapir]

I'm trying to increase the intensity of an emission on a material, but there doesn't seem to be a spot to do that

[deft fiber]

There's ways to use either
Lighting is difficult to bake on overlapping level geometry, and I'm not sure if static objects can be disabled anyway, but paraller universe can be implemented by having the level exist in two places and swapping objects between them rather than disabling/enabling

[deft fiber]

What kind of effect are you looking for? Translucency shaders are pretty good, but you might be able to get by with something as simple as giving the object an emissive texture and putting it on a different layer than the light inside ofit

[deft fiber]

Click this to find the intensity parameter

[fervent tapir]

Oh! Perfect! Thank you! ❤️You are Pre(tty)fab!

[hasty nest]

Hey uh, I've got a problem with loading scenes

I have a scene for the main menu, that loads another scene, the main game

Everything's fine when I'm playing the main game directly

But when I play the main menu first, then load the game scene, the light is completely broken :l

And I have no idea of why would it do that. The lights don't change at all they have the same setting

[deft fiber]

This usually is because scene lighting data is missing or incomplete
First make sure your lights are of the correct type, realtime, baked or mixed, depending on whether you want to use realtime lights or baked lightmaps

Then generate lighting from the lighting window

[bright escarp]

how to fix this weird shadows

[floral parcel]

Swapping them out for cubes instead of planes, and tweaking some of the shadow settings in the HDRP asset got rid of them in the end 🙂

[deft fiber]

Probably a texel validity issue
https://forum.unity.com/threads/faq-blocky-artifacts-appear-when-i-bake-a-scene-how-can-i-fix-them.951444/

[bright escarp]

thanks

[terse burrow]

Guys why spotlights cant cast shadows on URP
i have enable cast shadows at mesh renderers

[summer aspen]

make sure material used is of Lit type as well

[terse burrow]

yeah let me post screen shots of them

this is my characters material

spotlight

[bright escarp]

ANOTHER issue

[terse burrow]

urp settings

[bright escarp]

weird shadow

[bright escarp]

where do u get that setting

[terse burrow]

just made by myself

[deft fiber]

Hard to guess, looks like the lightmap resolution for that mesh is incredibly low, and probably overlapping with another part
The screen space ambient occlusion makes it hard to judge
Try looking at the lightmap debugging overlays in scene view

[terse burrow]

this is the scene

[deft fiber]

By viewing the URP quality settings asset in inspector
They can be located from the Quality tab of Project Settings

[bright escarp]

ok i see red spots is it bad ?

[deft fiber]

Yes

[bright escarp]

how do i fix

[deft fiber]

"UV overlap" is the problem, look into that

[terse burrow]

patchi do u have any idea about my problem

[deft fiber]

I don't see anything wrong with the settings, and I don't have any good guesses either
In that situation I would try to get the shadows working on an empty scene using default cubes and lights first

Always easier to troubleshoot on a clean canvas

[terse burrow]

yeah i have think about it and try with directional light

i can get shadows with that

only the spotlights are poblem

[deft fiber]

Do they work in an empty scene with all default settings?

[terse burrow]

with spot light ?

let me try

[deft fiber]

That would at least confirm if the problem is in the scene or project

[terse burrow]

oh no its not casting shadows on new scenes too

sorry i have enabled the shadow settings on this scene of spotlight and it works

so what is the problem of my main scene

[summer aspen]

@terse burrow In the Package Manager you can find URP package, it will have a button to import examples. After importing open a Lit scene in Shaders and compare settings with your scene.

Was typing too long...

[terse burrow]

im gonna try something on my main scene too if i cant find anything ill try ur suggestion

yeah same things works on my main scene too

i guess problem is floor and other things casting shadows but not receive that

but all the materials i have enable receive shadows

[deft fiber]

Progress, nonetheless!

Another troubleshooting trick I use is to move objects between scenes, as prefabs for example

So you can test the floor in the new scene, or test the light in the main scene

Or any such permutation

[terse burrow]

yeah did the same thing everything works except inside house 😄

guess problem is the lights i ll compare them

[terse burrow]

okay found the problem as u can see i have sett outer spot angle 179 degrees so its giving light source everything front of it with 180 degrees so shadows cant live at light sources 😄 i have reduce that to 120 its casting shadows rn

thanks everyone

i got another question shadows are faded when camera moves this far, i have try to increase shadows max distance from urp profile but not helped any idea ?

[deft fiber]

That's affected by shadow distance, cascades or some combination of the two
It might also be trying to fade to baked lightmaps using shadowmask but I'm not sure about that

[terse burrow]

there is a bigger problem here now i was trying to optimize lighting for mobile and try to bake some lights

UV overlap

baked lightmap

and shaded

[terse burrow]

as u can see my scene should look like this

ligth settings

whats wrong with lightbaking

btw its cool on when i use my lights are mixed mode

but the baked mode is terrible

[deft fiber]

@terse burrow Oof that didn't go so well!
Look into how to fix UV overlap, and check texel validity too

My advice, use the cube scene again to get baking working right
Easier to eliminate problems and won't waste so much time on baking complexity

[terse burrow]

yeah i check that but i cant understand anything properly

my native language is not english so sometimes i cant get too theoricaly documents

i ll take a look tomorrow i gtg rn thanks

[terse burrow]

btw in here if red things are bad vor uv overlap result should be really better than what i see rn guess problem is something else

[deft fiber]

There's probably multiple problems, so it's hard to tell

[terse burrow]

and last thing i have follow this guide to undertand URP Light Baking https://www.youtube.com/watch?v=okYhs6kQ0xw

[terse burrow]

yeah i guess to it may cause of the assets i have buyed idk ill look deeply tomorrow

[deft fiber]

A lot of the errors are because of the meshes, not the lightmap settings

But it can be improved

[terse burrow]

actualy i dont know should improve it for a mobile game

cause this game gonna be a hypercasual game so player can skip this hose in 20 min maybe

in small areas should i need to bake light mapping

i mean is that really worth for performance

maybe there is a graph or stats about it

[deft fiber]

You'll probably have to test it yourself
Monitor the performance and compare

[terse burrow]

i look at the call post or something in stats

its 260 while runtime lights

and 60 for the baked lights

but u know how baked lights look like 😄

[deft fiber]

It's worth learning how to get them working either way

[terse burrow]

yeah ure right

lets see tomorrow i'll ping u if i found a solution

[deft fiber]

Sure 👍

[terse burrow]

thanks again see u

[stark orbit]

how do i make the same object glow the same color it material is? and this method should work on prefabs

[mellow sierra]

You need to use bloom post processing to give something a glowy look.

[velvet pulsar]

Guys, why do I have problem like this when baking lights?

is it because the generated UVs?

the geometry is completed closed

[stark orbit]

im using that, with emmisive materials

[hazy plume]

increase ur uv padding

[slim flame]

This might be a shader thing, maybe a lighting thing. Idk so I'll start here. Everything you see has the same shader, same settings. Identical other than color. All the top surfaces are flat (at least according to Blender). Why does the pair of objects on the left act differently?

[drifting vale]

It really seems to be something with the shader. You could test with the Standard shader just to check.
If the behaviours also occurs with the standard shader, it might be the mesh (but, I suppose it is just a z scaled Cube, right?)

[stone gull]

Hello, I've recently downloaded an asset from unity which uses HDRP. I tried one of the scenes in the package but as soon as I played the game scene, all of the environment was blooming white. Where can I find the settings to lessen this effect and see clearly the environment?

[deft fiber]

The objects may be physically flat, but are their normals flat?
Vertex normals are used to bend light and make object shapes appear smoother and more rounded

[deft fiber]

Does this problem persists in game view, or in scene view if you bring the camera close to the houses?

My guess is that the brightness comes from auto-exposure trying to balance a decently lit house with the infinite dark abyss you're looking at below it

[velvet pulsar]

Why do I have this bleeding? Could be because of the roof being one single piece going from the inside to the outside of the house? The roof and the wall are touching

If I increase the scale in the lightmap I stop the bleeding. This make me suspect that maybe is the filtering bleeding through the wall

[deft fiber]

Check UV overlap view to check if you need UV padding

[velvet pulsar]

@deft fiber No UV overlaps

maybe that texel resolution is too small. I put the filtering to 1 texel but still bleeds

[deft fiber]

The geometry looks to be intersecting rather than connected
That's not wrong, but it's challenging for the lightmapper

[velvet pulsar]

yeah, is intersecting

I imagine that would be the case

so in cases light this needs more resolution to handle it better, right?

[deft fiber]

That'll help
I don't know of any more elegant solutions

[velvet pulsar]

is there a guide or something for good geometry for lightmaps?

in this case this is only a blockout but I imagine that for the final model the roof will intersect with the walls anyway rather than be connected

[deft fiber]

I don't know of such guides

The problem is that pixels on the lightmap will fall directly on the intersection, so they'll be both in light and shadow

The UVs could be tweaked so it's the pixel edge on the intersection, not the pixel
But that's very manual and not usually feasible

Or you could put some kind of baseboard or other type of mesh to cover the ugly shadow, which itself wouldn't cast shadows to the lightmap

But that might not be practical either

I assume you're using placing intersecting meshes specifically so you don't have to author the meshes of each structure variation

[terse burrow]

i have try with this settings result is same

[velvet pulsar]

@deft fiber in this case there are no other variation. I modeled that way because it was easy and will be easier to texture later

but I guess I can create a fake cealing inside the house and place the roof on top

the final model will be a cealing like this

goint out like this

that is why I choose intersecting geometry

[deft fiber]

Making the geometry continuous isn't a big challenge

[terse burrow]

i found somethig interesting

this is any spotlight

this is baked

this is on runtime

if i decrease indirect multiplier (wait im bakin)

this is how baked looks like

i guess indirect multipler means how many times that light can bounce or something like that

[outer glen]

Hi. I have an issue with my shadows when moving and pointing with a flashlight (spotlight) in my game. The shadows look like they are floating in the air. I have tried tweaking some setting like cascades, shadow distance, near plane, etc but couldn't get any good results.

Here is another video to see what I mean:

[terse burrow]

in here looks like light source on players left

u sure soucre is come from thing in the hand 😄

[outer glen]

the spotlight is on the tip of the flashlight

[terse burrow]

can u post a scene view from top point with the gizmos

its interesting

[deft fiber]

Rather how much multiplication is applied to the light strength when it bounces

[deft fiber]

The first video looks strange, but I don't see anything wrong with these images

[terse burrow]

looks okay if i draw perspective lines

guess its about the camera position

[outer glen]

In the scene view looks way better, the issue comes when I'm moving like in the video

[terse burrow]

as a player u can see lightsource just front of the camera but the shadows says lightsource comes from under the camera

do u get what i mean

[outer glen]

you mean the position of my spotlight is wrong?

[deft fiber]

It did look like that

[terse burrow]

no its correct everything its correct but players eyes just manipulating

[deft fiber]

But otherwise you will see "floaty" shadows if you hold a flashlight between you and the object
This will happen in real life too

[terse burrow]

exactly

[outer glen]

okay, I have to do the test in real life

but I have never noticed

[terse burrow]

look at this

thisis what happend

[outer glen]

would it change if I switch to Real Time GI instead of baked?

[terse burrow]

players sees lightsource just front of him but actually lightsource is below the camera view

[deft fiber]

this makes no sense to me

[terse burrow]

thats why u see shadows are weird u may fix it

[terse burrow]

teah thats too looks weird cause of my theory

[terse burrow]

look at this u will get it

[deft fiber]

The flashlight can't be baked as it's moving, and realtime GI doesn't usually react to any fast changes with accuracy

And even if it could, it doesn't fix any existing light positioning issues

[terse burrow]

wait isnt he using realitme ?

[outer glen]

I'm using baked GI

[deft fiber]

The flashlight is realtime

[terse burrow]

u should use realtime at dynamic lights

[deft fiber]

Even if the level has baked lighting

[outer glen]

the flashlight is in realtime mode

[terse burrow]

baked lights must used at static props like buildings etc.

[deft fiber]

All's fine regarding that

[terse burrow]

oh okay sorry

[outer glen]

but the point lights work good with the shadows

[terse burrow]

yeah i just experience same thing on my project too

[outer glen]

not perfect, but at least the projection is more accurate

[deft fiber]

You can improve "detached" shadows using this guide
https://docs.unity3d.com/Manual/ShadowPerformance.html

also called "peter panning"

Yep shadow terminology is like that

[terse burrow]

patchi do u know whats the green ares on baked lightmap culling draw mode ?

those

i have solve the UV overlap btw

but still i got this

[deft fiber]

hard to say if the problem is the lightmapper settings, the meshes, or the lights even

Do you get the same artifacting if you have another room made of just default cubes, with a default light next to that room?

[terse burrow]

i ll try, tryin another solution rn

[deft fiber]

The process that worked for me is just getting familiar with the lightmapper in simplest possible use case, then gradually increasing complexity with meshes and such

Meshes and more complex light setups can break a lot of things, or cause artifacts that look like errors but technically aren't

[terse burrow]

with default cubes

[deft fiber]

That's baked?

[terse burrow]

same light with scene prefabs

[terse burrow]

yeah

unbaked

[deft fiber]

The intensity should not change like that

[terse burrow]

i make intensity multiplier 0 then

its default 1 on environment settings

but still its increasing

[terse burrow]

if u have a project with URP light baking specially included spotlights can u share ur settings with me

maybe mines broken

[deft fiber]

You really need clean settings certainly

[terse burrow]

i do actualy

resetted all lighthinn settings and profiles

[deft fiber]

The sample scene URP comes with has correct settings

[terse burrow]

how can i import samples

[outer glen]

do you think assets like "bakery" would help?

[deft fiber]

No, the link I gave will help
Your problem has nothing to do with baked lights

[outer glen]

I have adjusted those settings, everything is to the minimum but I read that Peter Panning is a problem inside Unity built-in

[deft fiber]

I don't know if the sample scene is importable
You could just make a new project with the URP template and copy all the necessary values from there

[terse burrow]

checked already

im using deafults

i just changed shadow resolutions

im gonna create one new procjet for test it

[deft fiber]

Hope that works!

[terse burrow]

yeah works 😦

im a stuipd i guess its all about URP settings

baked and unbaked are same at new project

ofc with same light and props

[terse burrow]

im moving the stuffs to new project

on the new projcet i got this with baked

but when i add other props too result change like this 😦

i dont understand

i found the problem

i have using one way walls like this

only can view by inside

and if i add those behind the one face walls

i mean 2 different one face wall looks opposite direction

baking light is messing up

look at this walls are invisible on the camera but they got faces on other side and lights are not works properly

i may try to use culling masks but i need those walls any other idea ?

@deft fiber i hope im not distrubting u if u have a time maybe u have an idea

[deft fiber]

https://forum.unity.com/threads/faq-blocky-artifacts-appear-when-i-bake-a-scene-how-can-i-fix-them.951444/ here's a thread on that issue, which is revealed by "texel validity" debug view

This is how meshes can break lightmapping, which is why blank scene for testing is good!

[terse burrow]

yeah ure right ill try to decrease backlight tolerance

[deft fiber]

Ideally the backfaces should be contained behind the front face of the wall

But looks like they're totally exposed to the interior, so tolerance might not be enough

Making the walls two-sided should always work

[terse burrow]

actually i decrease the tolerance to 0

[terse burrow]

now looks satisfying instead of this

[terse burrow]

i know but i just buy the assets and that guy just made them like that

[terse burrow]

is that really nessesary i mean the backface tolerance

[deft fiber]

Try marking the wall material as two-sided first

Backface tolerance reduces the glaring artifacts, but still the lightmapper doesn't really know what to do with backfaces so the lighting won't be correct

[terse burrow]

its not about material

[deft fiber]

Or meshes

I don't recall where to option is

[terse burrow]

the guy flips the faces when its building the prop on blender or something else

its not an option i mention to say that 😄

i need to recreate all of walls for that

and i will try

i ll let u know about result

[deft fiber]

I mean this option

That should take care of it

if not, then this probably needs to be two sided as well

[terse burrow]

oh let me try

[terse burrow]

im trying with both render face

both render face instead of front

[deft fiber]

No improvement it seems

[terse burrow]

i ll try one more thing

we figure it out

i just seperate wall material with both rendering face

and other props are front rendering face

works like a charm

[deft fiber]

👍 ✨

[terse burrow]

thanks a lot patchi 🙂

if u need anything i can help u

[deft fiber]

nice ^^

[slim flame]

@drifting vale @deft fiber Finally got back to this this morning and did some more testing. All the cubes are at the same Y position. The orange cubes are Unity's 3dObect/Cube scale up to 40 units wide. The red cube is a cube I made in Blender and exported as an FBX. Same shader settings other than the color. In Blender the normals are what you'd expect for a typical boring cube.

Oh dammit

The smoothing was set to 90 degrees

At 89 degrees it works as expected

[deft fiber]

👍

[slim flame]

Thanks for the help. Got me where I needed to be to actually fix it.

[deft fiber]

I don't think there is any one typical vertex normal behaviour, it's kind of situational every time

[slim flame]

Yeah its a real doozy of a shader that I'm not even going to try to pick apart. hlsl is a strange language and I just barely have a handle on shadergraph.

[terse burrow]

@deft fiber https://streamable.com/ghh5gi here is baked lights gameplay

but i realize setpass calls at avr 50 at baked and 40 at realtime 😄

[deft fiber]

There's a big number of variables that affect performance, and tbh I don't know how significant setpasses are

[stark orbit]

Any ideas on this?

[terse burrow]

i heard about that on some light baking tutorial that guys said how much lower is that much better performance

[terse burrow]

im looking at rn wait

@stark orbit acutally i need same answers u know

let me check internet

okay look at this

i got this when i do emission color white

but if u made emission map same as texture

viola

[deft fiber]

That's the way 👍

[terse burrow]

if u want give emission particularly area just open ur texture map and black out whatever u dont want to be shiny

[near turtle]

Depends on some stuff

If SRP batcher is enabled, the "batches" count is defferent (this numbers on the stats will not be precise in this case)

[terse burrow]

acutally idk what is that i guess i need to lookup a real performance guide for mobile games

[near turtle]

Take a look at the Adaptive Performance package

[terse burrow]

noted 🙂 thanks

[stark orbit]

Thank you

[stark orbit]

nvm

[terse burrow]

i already ansered if u didnt see

[stark orbit]

i already thanked you

but its not really want i was looking for, besides i can't find your exact ways

and also changing colors

[near turtle]

You're trying to achieve this?

[stark orbit]

sorta

[near turtle]

Do you have bloom active on a global volume on your scene?

If it does, than emission will begin to "spread" from the surface

[stark orbit]

yes

[near turtle]

Enable tonemapping "ACES" and HDR on your camera to improve the effect

[stark orbit]

an old image of what i have, i've changed a bit since

[marsh sapphire]

Hey having an issue here and wondering if anyone might be able to help. Have a project I am working on with an avatar and it requires specific versions of Unity (2019.2.4f for one, 2019.4.29f for the other) I an NOT a dev, just tinkering with 3D models here, but think the issue I am seeing has to be related to the different versions. In the older one, the model and textures all work as expected, with emission working. In the newer one, however, the emission isnt working (see photos) any thoughts on how to fix this in the newer version??

[near turtle]

emission color is black here

[near turtle]

is this what u want then?

[stark orbit]

yes but i want every instance to have a different color

[near turtle]

gotcha

There's a lot of ways to change that

Different materials, use an texture atlas with a color palette to use just one material but each sphere has one color...

[stark orbit]

well i thought of that, but its not a viable option

because you will end up with tons of materials

[marsh sapphire]

It should be that texture file

[near turtle]

not necessa

[marsh sapphire]

Thats how it is in the previous version

[near turtle]

Click here ang change it to white

[marsh sapphire]

Omg that worked!

Can you explain at all why that was needed

[near turtle]

https://www.youtube.com/watch?v=ZTwCWbV-QGE try collor palettes

[near turtle]

this other color multiplies the one coming from the texture

So it was "tinting" it pitch black

[stark orbit]

i have a problem with recieving light from ammisive materials
but thank you anyways

[deft fiber]

Then why didn't you say so

[stark orbit]

because its new

[deft fiber]

Emissive materials generally do not emit light to nearby surfaces, but there's a lot of workarounds depending on the use case

[near turtle]

Yeah, to emit light coming from emissive you have 2 options that I'm aware of, baking it, using ray tracing

You can also attach a point light with no shadows to fake the effect, but it is resource intensive

There's a paid plugin that kinda solves it, it's called Upgen Lighting, search for it on the asset store

It produces much lighter point lights

Then it becomes viable

[odd yacht]

https://youtu.be/uwYf1yMPuvk Best tutorial ever made

[limber delta]

Hey! I was wondering if there is any way to make area lights produce a softer falloff? And why does rectangle shaped area lights look like spotlights? This is from the Unity Manual: "Light is emitted across the surface of an Area Light producing a diffuse light with soft shadowing." I don't see that happening.

Btw, there are 3 area lights in that area, hence the 3 circular light shapes.

And while I'm at it. I get this error usually when going from 2k to 4k in max light map size. So I only bake 2k maps. It goes on like pictured below and the app stops responding. I have to shut it down and restart.

There are like 20 lights in my scene and so far baking has been working without issues with a 2k lightmap size (bakes in like 5s), until just now. I'm still on 2k in max lightmap size, but I changed the area light to circular and upped the lightmap resolution to 40. Then the error occured again. It's quite annoying as I can't seem to bake higher quality lightmaps.

I'm on a Ryzen 9 5900x and Nvidia RTX 3070.

Appreciate any help, thanks!

Btw, my lighting mode is: baked indirect and all my lights are set to baked. I'm using the progressive GPU lightmapper.
I'm working in the URP!

[lucid mesa]

how I can create a lightsource? If I press rightclick I can create a light (spotlight, pointlight, etc.) but it doesn’t emit any light

[deft fiber]

Find tutorials or the documentation

[lucid mesa]

no shit

thanks for nothing

[deft fiber]

It's the standard procedure for every problem
It's impossible to guess what the particular issue is if it's not a common one, so the best thing you can do is to follow a guide on an empty project and then ask for help when a specific problem surfaces

Lights not showing up is not a specific problem because it might have dozens of possible causes

[fluid bolt]

Guys, do you know why I can just see the color material if I'm very very close to the object? I'm using URP

[forest swallow]

seems that every time I rebake my lightmap, my reflection probe loses all its data and I have to re-bake it again, using unity 2021.1.19, is this a bug..? or is there an option I need to change somewhere

[gentle sky]

Is the a way to attatch 2D lights to particles?

The "Lights" section in the particle system only works with 3D lights, is there some other way?

Not officially, but you can find a script in this thread by an unity dev that'll attach 2D light gameobjects to particles
https://forum.unity.com/threads/lwrp-using-2d-lights-in-a-particle-system-emitter.718847/

[gentle sky]

Oh sweet! I'll try it out, thank you!

It worked! Thanks a bunch!

[neat drum]

how can i make the light emit outside of the lamp object and not trapped inside of the object?
i don't want to place the light below the lamp or in front of the light
the scene has baked lighting, and the lights are set to mixed mode

[outer glen]

any opinion on the lights/Lighting?

it doesn't look too real imo, but it's better to read an opinion from the outside

[deft fiber]

Lights have a "clipping distance" to stop objects too close to them from casting shadows, but I don't recall if that was for realtime only
Layers work, at least

[neat drum]

so a culling mask then?

i'll try the layers

[fathom furnace]

Not entirely sure if this is a lighting issue or what, but Imma just assume it is.
How would I stop the right wall from having that "reflection" on it?

Both walls have the same texture.

[fathom furnace]

Looks a tiny bit flat in some areas of the walls.

[fathom furnace]

Plus the walls look slightly "too reflective", I feel like they wouldn't be as reflective as the floor, cool floor reflections though.

[lucid mesa]

imo the floor reflects too much light. It looks too smooth

[fathom furnace]

Fifty layers of wax.

[outer glen]

haha yeah all the props to the janitor

[fathom furnace]

Also that's with the res turned up, this is the standard res of the game which makes it even more obvious.

I thought it was fog at first but apparently not.

Ok I just found a "fix"

But it's not something I wanna rely on all the time so figuring out how to disable this would be nice.

[neat drum]

ok so i tried to add a layer for allowing the light through

it still traps the light inside

[fathom furnace]

Ok nvm it's still there.

My "fix" made it way less noticeable but it isn't gone.

[deft fiber]

This looks different from the earlier reflection sheen

The reflection was uniform across the surface, this looks more like mipmapping

[fathom furnace]

Hmm.

It's the same surface, one just has a 70x70 render texture applied.

Well they're both render textures by the top one is much higher res.

[deft fiber]

Do render textures even have mipmaps

[fathom furnace]

🤷

[deft fiber]

@fathom furnace anyway I think what you're looking at is reflections from the skybox, like this

[fathom furnace]

Hmm

[deft fiber]

You can turn the material smoothness way down to get rid of them

Or if you're not intending for surfaces to have realistic lighting anyway, use some shader that doesn't deal with reflections at all

[fathom furnace]

This did in fact work, thank you.

[deft fiber]

If you do want realistic lighting, reflection probes are normally used so that there's still that sheen, but it'll be a reflection of the surroundings rather than skybox so it'll look better

[fathom furnace]

I forgot there were even materials, I thought it was just using the images.

[fathom furnace]

I'll have to read up on shaders some day, don't know much about them atm.

[neat drum]

on a followup, i fixed my problem, i had to turn "Cast Shadows" to off for my lamp mesh renderer, now the room is lit up

[outer glen]

Any alternative to realtime point lights? I have many buildings in my map with switches to activate the interior lights (point lights) but I noticed that it has a significant cost in performance. I have read some games faked the lighting but how?

[haughty plume]

do they cast shadows?

becuase of they do, they are casting 6 of them per light

i have found if using deferred lighting, make sure the range means they dont overlap

[outer glen]

Yes they do, otherwise the light pass through the walls

[haughty plume]

the amount of lights affecting per pixel costs performance

so can you not use like, a single wide spot? or an area light?

does the camera move around or is it static?

[outer glen]

The area light is baked that’s the problem

[outer glen]

Yes, it moves, it’s a first person game

[haughty plume]

you can have realtime or mixed area cant you? or is that only on hdrp

[outer glen]

Maybe only on hdrp (haven’t used it), I’m using built-in

But built-in has only baked as an option for area lights

[haughty plume]

defo hdrp yeah

i havent used built in in any serious way, i went right into hdrp. but i've had to avoid point lights completely if they cast shadows as they are 6 times more heady, they make a cube map

[outer glen]

Yeah 😦

[haughty plume]

baked lights look naff almost all the time

[outer glen]

Can’t really switch to hdrp

Some pf my assets are not supported

[haughty plume]

yeah its still a problem

some can be converted with shadergraph, some just cant

[outer glen]

I can’t also baked them as they turn off/on

Damn

[haughty plume]

you using deferred lighting tho right?

[outer glen]

Yes

[haughty plume]

well, i'm not an expert, so dont take my poor advice as it not being possible

i'm going through lighting pain too and trying to fake my way around

was just about to post here myself about something else

car headlights, if they cast shadows its heavy, if they don't, they shine though stuff. i can (and have) make a fake volumetric style cone and that helps performance, but still by design shines through stuff. i'm curious if there is some known trick to this

[outer glen]

Yeah lighting is a big pain

Couldn’t tell you on hdrp

Just know that there is an asset on the asset store called volumetric lighting maybe it could help you

[haughty plume]

might be similar to the tut i followed, i made some volumatric street lights and they look great

but they have a real light doing the lightwork

confirmation for anyone wondering, the fake headlights i just mentioned actually look naff and they dont light anything up and dont save much performance where shadows are not enabled

fun and games 😛

[mental pulsar]

Hi! Any idea why light map disappear when i click on play in Unity?

[severe wigeon]

So I am trying to make a lightmap for one szene of my game when I select auto generate small changes happen but then it keeps working and says that it would take more than 3 days that can't be right or?

[harsh raptor]

How do you turn of lightning in unity 3D? I have only worked with 2D before and trying to create a 3D game now, but since Im just starting, I dont want to work with lightning for now. Is there a way to disable it?

[mellow sierra]

Why not just leave it. Working in a completely black scene is going to be impossible to do anything.

Otherwise, you can delete the lights in your scene for starters.

[harsh raptor]

With disabling it I mean making the scene not have an dynamic lightning at all and everything having a constant light so that textures and stuff like that look the same as it does in the image editor

At first my problem was that the light was way to darker from most of the sides and now I seem to have broken it completely and my object is just black

Okay never mind fixed the issue that it is completely black, now I only have the problem that it is too dark

[deft fiber]

In scene view you can click the light bulb icon to disable lights
If you want everything to be lightless in game view as well your best option is to use unlit shaders on all objects

Or remove lights and only leave ambient light on in lighting settings, but PBR materials might to look weird

[harsh raptor]

How exactly do I use unlit shaders on objects?

[mellow sierra]

Change the shader on the material. Unity has a built in unlit.

[hazy talon]

how can i make a point light from URP not affect a certain sprite

[stone gull]

I want to enable this option, but I can't find it in my objs. Where can I find this settings in my object?

[jaunty briar]

Selecting your object in the 'Project' window. It's the import settings.

[sterile iron]

why zombie desapear withtout reason ?

[deft fiber]

Usually with skinned meshes this happens because the mesh's origin point gets off screen, away from the mesh itself
But hard to say for sure
https://docs.unity3d.com/Manual/class-SkinnedMeshRenderer.html#bounds

There's a part down there that says ragdolls can cause this too

[sterile iron]

sad what can i do

@deft fiber

[deft fiber]

What does the article say?

[sterile iron]

enable update offscreen

@deft fiber

[velvet ermine]

Guys, please help.
I turned off all Lights in Scene.. but why I still see everything like during the night. Shouldn't it be completely black?

[deft fiber]

Are you perhaps using baked lightmaps or ambient lighting?

[velvet ermine]

I cleared "baked lightmaps" but not sure how to check ambient

[deft fiber]

Lighting window > Environment tab > Environment lighting

[velvet ermine]

All tabs in Lighting Window set to None.

now i see this

looks like the Sky is my light source. No idea how to disable it

[deft fiber]

There are many options that can disable ambient/sky lighting
Setting Source to a black color for one

[velvet ermine]

I cant find any source of the light @deft fiber

I turned off all objects. So its not part of the scene. But someehere in global project settings

[wind socket]

anyone can recommend me a lighting course or videos or blogs from unity to read

to set different post processing and light settings for different moods?

like i want the village to be happy vibrant but the dungeon is not happy at all

its tense environment and kind of dark

[warm geyser]

how do i make these wall segments not lit individually

[stark temple]

It honestly just looks like their normals are wrong, not that you want to light them together

[warm geyser]

idk what that means

[stark temple]

In the model importer switch from Import to Calculate and see if it fixes your issue

[warm geyser]

o it did

tysm

i was pulling my hair out over this

[stark temple]

If you made the models yourself you should learn how to recalculate the normals in wherever they were authored.
It's the vertex normals that are pointing in the wrong direction. You'd usually point them in different ways to change the way surfaces look (to make them appear smoother, or lit from a specific direction). Otherwise something close to the default recalculation is good.

[warm geyser]

i know shift + n in blender and stuff

i tried that

didnt work

[stark temple]

You should go here, turn on autosmooth and set the angle to a value that suits you

[warm geyser]

o

[deft fiber]

Did you set the ambient light source to a black color like I instructed?

[floral parcel]

Anyone know how to get rid of the light bleeding at the edge of the frame. It seems linked to contact shadows, they disappear in the center of the screen but as soon as I move around light leaks in at the sides of the screen

[marble coral]

Hi i want to use deferred rendering but i am getting these circle but when i change to forward it work fine?

[deft fiber]

I don't recognize that, but what I would do is check if these are enabled:
Linear color space
HDR
Dithering

By dithering I mean the camera effect that reduces banding by adding some dithered noise
I might check that first actually

[marble coral]

thanks by enabling HDR it solve the issue

[warm geyser]

this looks similar to a bug i had, change "import" to "calculate" for the normals on your mesh import settings

see if that does anything

[patent relic]

Does anyone know how to make this app https://assetstore.unity.com/packages/vfx/shaders/toony-colors-pro-2-8105 do an hair with a light lining like this forth kind of hair: https://media.discordapp.net/attachments/698181399168942161/884902713941458994/2Q.png

[placid cosmos]

thoughts

[wheat bloom]

super reflective & transparent

[forest swallow]

hi guys how do I get rid of these lights bleeding through my mesh? if I play around with the light's Angular Diameter, setting it to 0 does get rid of them, but my shadows become very sharp, and I want them to be a little soft

oh and it's HDRP

[deft fiber]

Really nice use of translucency!

[deft fiber]

this is a weird issue because it pops up for someone every now and then, but everything I can find about it says that it's "normal"
https://forum.unity.com/threads/new-to-hdrp-should-contact-shadows-look-like-this.836809/
Like replies in this thread

[forest swallow]

great

I really wonder how people feel generally about HDRP

[deft fiber]

Did you check if post processing is enabled when that grainyness happens? Could be some smoothing step there

[placid cosmos]

thanks

[placid cosmos]

is that a critique

[forest swallow]

nah, I only checked through the scene window

if I play around with Angular diameter on the Light it can fix it, if I set it to 0. but that does other weird things to shadows

[deft fiber]

Seems to me there's some filtering option missing
Maybe best trying to find that before changing the properties of light and shadows

[spice bloom]

Hi i am making the environment and character in different layers so i can use different lights ( because of my artstyle) but the characters layer have no shadows is their any way i can cast shadows of character(lights are different) on my environment layer please tag me with possible soluation. Thanks

[deft fiber]

You mean the player layer needs to cast shadows but can't be illuminated by that light?

[spice bloom]

yes lights emiting environment are different and light for characters are different i want it to cast shadow on environment, i am not wokring on game or its for cinematic and manga so if there is some cheap hack i can go with it since i will later paint on that litl etoo but i want shadows to comeout naturally

[lucid mesa]

hey I have 8 spotlights in a scene and they all have exactly the same properties. But somehow only 5 of the 8 lights work?

[deft fiber]

The default pixel light limit in forward rendering is 4 per object

[lucid mesa]

I read this

Try upping the pixel light count:
Edit > Project Settings > Quality

but I can’t find pixel light count in the settings

what exactly is it called?

[deft fiber]

@lucid mesaPer Object Limit in URP

In the quality setting asset, not quality setting window

In built-in RP it's in the quality setting window

[lucid mesa]

I don’t understand what this means. Do I have to install an asset?

[deft fiber]

Is your project using Universal Render Pipeline or the built-in Render Pipeline?

[lucid mesa]

URP

[deft fiber]

URP stores quality settings as assets

[lucid mesa]

how can I access them?

[deft fiber]

clicking the asset slot reveals its location in project window

[lucid mesa]

ahh thank you

[deft fiber]

@lucid mesa Regarding that, there are other ways to avoid light issues
Light limit is low because overlapping lights are expensive
The expense and limits are per-object, so you can split big meshes into smaller ones
And most importantly decrease light ranges so objects won't be within their area of influence unnecessarily

Baked/static lights do not suffer from this limitation so games often combine static and dynamic lights creatively
If you really need a lot of realtime lights, you could look into Deferred Rendering which is designed to be very performant with dynamic lights

[lucid mesa]

oh so if I bake the lights, the Per Object Limit doesn’t matter right?

[deft fiber]

It won't, but baked lights can't move and only affect static, unmoving geometry

[lucid mesa]

yeah I know that

I already tried baking once

but once it was done

the mesh turned completely black and there was no light

[deft fiber]

Worth giving it another go sometime

[lucid mesa]

yeah I’ll figure it out

thank you

[deft fiber]

Good luck 👍

[stark marsh]

Is there any way to use the unity standard shader in dark scenes not do this? Every single model "glows" in dark scenes using the standard shader. Some kind of mini-emission...

[jaunty briar]

It's either environmental lighting in your Lighting window > Environment which you'd want to set to black or reduce to 0 in this case, or skybox reflections.

[hard heart]

does lighting get stuck sometimes? and is there anyway to nuke a stuck bake and reset to default or whatever?

it's just a shit learning project.

I've been at 93% / 3 min for over an hour now

[hard heart]

okay well that finally finished. I have another question! IS there a way to prevent a specific light from reflecting? I wanted to slap a spotlight above my character to illuminate the area around it at night, but the floor is reflective and it looks dumb.

[olive python]

Anyone know why my light bleeds through rooms? :\ using URP with probuilder. @ me if you have any help , thanks!

[jaunty briar]

adding some thickness to your walls help. You can also play with the light's bias settings. (lower depth and normal)
You'll get other light calculation issues closer to 0 though, so look out for those.

[olive python]

i disabled directional light for now but getting this weird issue with lights

[jaunty briar]

That's the lights pr object limit with URP (or forward rendering). You can increase it to 8, but that's as high as it goes. Need to select your "UniversalRenderPipelineAsset" and set "Per Object Limit" to 8.

[olive python]

oh this means i can only have 8 lights?

[jaunty briar]

It's pr object in render view at any given moment. So, if you have 4 lights in your scene and the limit is set to 2, then only two of those lights will affect the same object at any given time. If you are to move past one of the light sources, another one will kick in. Which is what I think is happening there when you scroll closer towards it and look around.

Of course, baking your lights whenever possible is the recommended route regardless. Better quality and less taxing than using realtime pixel lights

Setting your lights to "not important" also should get rid of that flickering issue. But won't result in as high precision lighting

[olive python]

ok yeah ill def keep the baking in mind for completed level i just wanted to be able to preview my changes real time, the Bias to custom def helps control some of those bleeds, thanks!

[jaunty briar]

You can try setting the light's 'Render Mode' to 'Not Important' in the meantime then. Should get rid of your flickering anyway.

[olive python]

gets rid of the light altogether when i set it to that 🤔

[jaunty briar]

Hmm.. that's strange. Guess not then 😅

[olive python]

it's like half of it is there and pops up when it feels like it

[jaunty briar]

Yeah, so the only way around that with URP is to have your walls and ceilings separated into multiple meshes instead of one giant piece. At least split into rooms.

[olive python]

should i use HDRP instead?

[jaunty briar]

It all depends on what your target platform is

[olive python]

wanted to keep it webgl mainly, but want the lights at least to work correctly lol

@jaunty briar can this be related? i only opened the project in 2021 and this came up

[jaunty briar]

They do work. Pixel lights are expensive. It's one of those things where you have to build your level while keeping all these things in mind. "How many lights will I have?" "How many lights will affect a single object in this area".
One ceiling or floor piece covering the entire level is definitely not good practice.

Idk about that one. I don't think that's related to your flickering

[deft fiber]

@olive python Splitting mesh objects and decreasing light ranges is usually the way around this
For very general lighting it's often better to bake and use reflection and light probes to allow dynamic objects to share the baked lighting

Or you can look into deferred rendering which is designed to support a huge number of dynamic lights, if you really need them

[spice bloom]

does anyone have any solution to this

if yes please tag me

[deft fiber]

@spice bloom You could have a duplicate of the character mesh that's set to cast shadows only
If I understood it correctly

[spice bloom]

yes sonething like that but how can i get shadows if my mesh rendered will be off

i got it and thats seems more logical but how can i get that @deft fiber

[deft fiber]

mesh renderers have this option to make them invisible, but still cast shadows

[spice bloom]

@deft fiber ooh thanks you saved my life

[mild tangle]

yall how do i bake lightmap for individual scene

wen i bake one it overide all the scene

[deft fiber]

Without hacks, lightmap baking is always per-scene

I don't know if you want to bake only a part of the scene, or your problem is that every scene's lightmaps are resetting somehow

[mild tangle]

well i think yes its my scene's lightmaps are resetting somehow

my another scene lightmap is gone when u bake something in other scene

maybe imma try again

[deft fiber]

There's a Lighting Settings asset created when you configure lighting for a scene the first time

Make sure different scenes aren't using the same Lighting Settings asset

Not sure if that's the issue, but might help

[mild tangle]

wait its this thing?

ok i think i fuc up

i use it in all scene

[lucid mesa]

so I just baked lights for the first time. Now I want to make my player have shadows that change direction depending on where the light is coming from. Do I need to use realtime lighting for this?

[olive python]

What am i doing wrong...a good engine but this lighting thing is furstrating to build anything if i can't visualize how it will look , i tried using baking and nothing helps with this

😦

inconsistent lights... for a few, they're marked as baked, how the hell does unity cramm a spot light and a point light in one row of 6 for just one lamp(in their example scenes)... here i am struggling with 7 lights

[deft fiber]

Scene view uses dynamic lights for baked lights until they are baked

So you can get a preview of how they appear before baking

Note that the geometry needs to be static so light can be baked onto it

[olive python]

so what i'm seeing is normal ?

and everything is set to Static
