Which was?

[timber lichen]

Hi there, can someone tell me, why there is no lightmap slot in the HDRP Lit shader? In the old days there was this feature. I just want to understand the meaning behind it.

https://docs.lightwave3d.com/lw2019/files/2791095/2791101/1/1468589978000/Unity_Lightmaps08.png

I want to use a custom baked lightmap (Blender Bake in second UV channel) in the standard HDRP lit shader. But I rly dont know how to overlay/add/multiply the lightmap to the lit shader.

How to use RTX lighting in a game?

[olive iris]

Raytracing

[olive iris]

Have you checked the lightmap tabs?

[small crane]

Hello, I have set up my project with HDRP but I have some issues with my lights, like in the picture it seems like they are pixelated. I have also set up volume and fog and this seems to be the problem, how can I resolved this ?

[rustic raft]

Would it be a good idea to have a constant light in a 2D game attached to the camera for an entire area to be the sun or is there a better way of doing this?

[olive iris]

What did you try so far?

[olive iris]

Depends what you are trying to do

[rustic raft]

Just trying to make a sunlike glow in the top corner

[waxen wolf]

Something in the urp settings that I found on the 2nd page of a google search

[keen locust]

Don't know where to ask this so I'll ask it here
I am trying to make a trail effect go on a circle but it is going above the circle and I need i to go under, is there any fix for this?

[olive iris]

Sounds like particles?

[small crane]

So far, I've just add a sky and fog gameobject in the scene and set it up like this.

[icy tundra]

So URP still doesn't fully support multiple directional lights in a scene?

Or is there some arcane workaround?

[olive iris]

What do you mean?

[olive iris]

how come you did not add hdri sky at the bottom?

[small crane]

I've just figured it out, lol.

[icy tundra]

@olive iris I mean that URP does not officially support using more than one directional light in a scene, unless there is something I am missing.

[olive iris]

Do tell it here for others. 🙂

[small crane]

Mb sorry.

[steady galleon]

Hi All, I have a very simple low-poly scene using URP in 2020.3.6f1 and I'm in the process of trying to boost performance on Quest. The original scene is almost completely unoptimized, no baked lightmaps, I like the look of it but the frame rate is too low.

When I just set all the static stuff to Static, bake a light map using default settings, it really looks horrible; note particularly the smearing on the wall above the laptop and the way the shelves on the right have gone black.

So I've watched some videos, read some stuff, but can't see why this is happening. Can anyone suggest where I should look for the root cause of this? I know there's a ton of settings but I was hoping to be able to just bake the shadows into the textures on the walls and floor and disable real time lighting. Not so easy apparently. I have one directional light in the scene and two point lights, all set to "baked". No real-time in the scene. Thanks in advance.

[fallow thicket]

Can anyone help me with a lighting issue? I'm not sure if this is because I'm using amplify shaders or not, or if Unity is just shitty at baking lighting.
My issue is that when I bake lighting, it is completely nullifying my roughness and normal map. I have no idea why. Here's a before and after when I bake lighting and my settings used when using Unity's standard CPU light baker.

[mystic dew]

hey, show to me your baked light scene view with pixel texels on surfaces

[mystic dew]

you are using baked indirect that apply albedo map only. try to use shadowmask mode

[hallow stratus]

I got this scene with baked lights, The environment is one mesh and the house another. Why after baking is the house so dark all over the place. It is using the same texture as the environment

these are my lighting settings:

[steady galleon]

@mystic dew thanks for reading. I am not 100% sure this is what you're asking for, this is "Baked Lightmap" draw mode; is this "pixel texels on surfaces"? I googled that, cannot find it precisely. Thanks.

Or maybe you meant "texel validity", which looks interesting and maybe is a clue that some of my texels are invalid:

[mystic dew]

your texels very deformed. make sure you have generated light map uv check box ON

Here is my example, you can see that texels is have quad shapes and density of texels is pretty high.

[steady galleon]

OK @mystic dew - awesome - thanks SO much. This is really helping! At first it didn't help, but I selected all models in my project and checked the "Generate Lightmap UVs" in the model import settings for all of them, re-baked, and it looks a lot better already; this was complete garbage before; the shelves were messed up. I have to step away but you've been really helpful, thank you.

[mystic dew]

no problem

[dapper glen]

Wow the progressive lightmapper is "great" !

[drifting vale]

Not sure if the issue is that. But it seems the Lightmap is set to be on a very small size or using a strong compression on it. Resulting on low-quality baked light.

What is the Lightmap Size for this scene of yours?

Oh @steady galleon , it seems it is already solved. (My chat didnt scrolled properly, lol)

[steady galleon]

@drifting vale thanks for replying - yes this is solved, also my setting (in 2020.3.6 it is "Max Lightmap Size") is 1024, same as yours.

[lost whale]

whats the best lighting seetings/options? for outdoor environments

im currently using realtime global illumination but im wondering if i can get it to look better

sorry for the plethora of images

First time im trying to do really good lighting in unity, and im not as used to it than unreal

[drifting vale]

Just to have context, would it be for a PC/Console/Mobile, or Just exploring and having fun?
Realtime GI seems kinda expensive, I would recommend trying things with Baked GI with Shadowmasks

Shadowmasks allows you to have realtime shadows even with a baked indirect light. (Until the Shadow Distance)

But well, if you are only having fun, I would recommend trying the Post Processing volumes

there are indeed a lot of cool filters to play around to make it visually more interesting

With a baked GI, you could also experiment increasing the number of Max Bounces, to have a Lightmap with a more accurate of how light bounces around the objects.

Sorry if some of the terms I used are different from what it is on Unreal. 🙌

[lost whale]

@drifting vale mainly for pc, would like to have a webGL build though so i could embed it into itch

pc download would have better graphics but webgl build would run smoother i guess? or just to have both run smoother

[drifting vale]

Yeah, WebGL is kinda problematic on some points. It is always a experience of building and checking if everything is running smooth, but it is always satisfying to see good results running on the browser. Huahua

[lost whale]

true

[olive iris]

@hallow stratus You should check your settings for the meshes that they are all set to static, uv map is produced and that this is not actually the shadow of the light.

@lost whale This is less about setting and more about just understanding lighting. I see a lot of people focus on the settings but the settings are not the real problem here. If you look at your image you see that objects are not receiving lighting correctly. They are standing out. And shadows are not correct either. These are the things you want to fix. And then you also want to increase the contrast a bit too.

[fair basin]

this is how a directional light looks on my round earth (left) and my 2d earth (right) is there anyway to keep the earth round and achieve the same lighting as right, the right one is more balanced with lighting

[lost whale]

@olive iris

alright trying to adjust it a bit more to be darker

the weird thing is that alot of objects still have shadows working

ah made it too dark

the leaves are all broken

yikes

what should i use for environmental lighting? skybox?

ah yeah skybox, anything else destroys the trees

man im not that good at unity lighting

[olive iris]

@lost whale what pipeline you using again?

[lost whale]

just the base one, should i use the other pipelines?

[lost whale]

Urp or hdrp I think are the two others right?

[olive iris]

@lost whale are you comfortable sending me the scene so I can make a video for you?

If not this might help teaching you the thought process for now https://www.youtube.com/watch?v=jgQrJ1qKxpM

[jaunty olive]

My road not caching the shadow....what should I do?....this road is made with easy road

[olive iris]

@jaunty olive raise it up in the air and check if it cast shadow for real

And check the easy road tool settings for that matter

[jaunty olive]

yea those are working I think the problem is with the material

I am noob ...... don't have much idea on sharers 😅

Oh I fixed it

[olive iris]

good good

[timber lichen]

hey there, is it possible to use a directional light just for casting hard shadows and not lighting the scene? the scene lightings comes from an HDRI, but the shadows are too soft.

[olive iris]

@lost whale I will upload this short tutorial on how you can think, light and approach your level. This is how it looks like quickly.

[bold flame]

this means i have to bake my lighting i assume

or how does it work

[bold flame]

Should I be generating lighting

?

[olive iris]

@bold flame Kind of odd question....

[bold flame]

wdym

was it a stupid question

[olive iris]

haha...no but it does not make sense.

[bold flame]

See

[olive iris]

If you have to bake lighting, then bake it.

If baking does not work, then tell us what you did so far.

[bold flame]

i have like 0 clue how lighting works

[olive iris]

Clearly...

So what did you do to go learn basic lighting?

Did you read the basic documentation? Did you watch basic unity videos?

You did not provide any information on what you have tried so far. So we do not know where to start. The most obvious things is did you turn on static for baking? @bold flame

Other things is what pipeline are you using...

[bold flame]

urp

[olive iris]

So, did you turn on static?

[bold flame]

Static meaning?

[olive iris]

@bold flame That sounds like a no.

[bold flame]

so what do i do

[olive iris]

Well since it is a such a basic question...Id go learn basic lighting. 😄 I can find you a better tutorial if you did not find Brackeys good enough.

[bold flame]

sure

ill go do that

:D

being condescending as hekc doesn't help anyone :-)

[olive iris]

To answer your question though...

[bold flame]

you know

all i was asking was

if i should click that button

because

a bit ago

[olive iris]

Your button is on top right.

[bold flame]

i was told on this discord that i shouldnt click it

[olive iris]

Exactly

So should you not be able to figure things on your own if people are giving you wrong answer? And if someone is giving you wrong answer are you asking the right questions? See, this gets complicated. 😄

Static is on top right.

[bold flame]

the cog?

wait

or new lighting settings

????

[olive iris]

I will help you but I need to ask

Why have you not watched learning content...anything to learn this?

[bold flame]

brackeys lighting

but like

not very how do u spell it

thoruoghyly

my mistake

but like

...

._.

[olive iris]

There is a square up there...click it to turn everything on.

[bold flame]

on what

[olive iris]

Now, because you might need this info in the future...if you click the down arrow or black icon it will let you choose among the possible choices...including reflection static building

[bold flame]

mm

[olive iris]

Alright..

[bold flame]

i am listening mr mentor guy

[olive iris]

take a screenshot of your INSPECTOR after selecting YOUR black meshes.

[bold flame]

oh

they are now all static

[olive iris]

Does not mean it will be fixed but it should be.

[olive iris]

I assume you clicked bake....and rendered again.

[bold flame]

ah

makes sense

ok

shh

i am the smartest person u know trust me

uh

[olive iris]

See...this is why I told you to go learn

Because people who ask this do not even know the follow up issues. 😄

[bold flame]

Ok

well

[olive iris]

BUT

[bold flame]

oh my god

[olive iris]

I will tell you this too...but you really should be watching other content besides a single video from a single youtube channel.

If you import or model your own meshes, or sometimes for whatever reason...you did not make your own lightmap UV...you should click your meshes in project folder and generate uv map.

@bold flame Also, this might be useful for you read because people only ignore you or say this to themselves rather than directly to you. 🙂 https://www.amitgp.com/how-to-ask-game-dev-tech-questions/

[bold flame]

ok mentor

[olive iris]

@lost whale I know your probably sleeping. But I made this tutorial for you https://youtu.be/CLHo8eU26qI since it can not be written.

[safe fox]

i cant

[winged gorge]

this may have already been asked before but do we have a date on when Flare Layer will be available in HDRP/URP?

[olive iris]

@winged gorge Nothing in general in the roadmap?

https://unity3d.com/unity/roadmap/)

[inner edge]

Hey, i've got a question about shadows. When changing from a physically based sky to a HDRi sky, my shadows just loose all of their color, what am i doing wrong?
https://images.mgroeneveld.nl/images/eee17640.png

[olive iris]

@inner edge it uses the hdri so change the hdri sky to the tone you want, edit it in post process but I dont recommend that. Change settings in environment maybe... etc

[lost whale]

Im... probably gonna lower the quality settings for the lightmapper quite a bit

since like.... 18-24 fps dips

theres definitely better ways of optimization but hm

[lost whale]

@olive iris

redid all the lighting gonna keep as is until i revisit it sometime this summer

[lost whale]

been toying with the interior lighting for the two buildings for a while now

getting some weird lighting on the main house

no clue as to why

just toying with it until the weird artifacting goes away

[olive iris]

did you click the mesh and generate uv map?

[lost whale]

yep

Im not sure what i did but its gone now

[lost whale]

im thinking i did something wrong in probuilder when i made the buildings

as its generating some weird shadows from the interior lights outside

[safe fox]

why dont use blender for modelling ?

[distant lotus]

I'm having a little problem where the shadow is not showing on the walls. They are set to receive shadows, yet are the only objects that are not actually receiving shadows. I'm using Unity 2019.4 and URP.

You can see the shadow bleeding in under the wall.

[olive iris]

What did you try so far?

[ionic smelt]

Hey I faced some problems in unity 2020.3.3f1 (URP - 10.3.1) I get some weird artifacts after baking the shadowmask https://gyazo.com/daed21f00257b813fbbb4470ecb55339 does anyone know a fix for that? 🙂

[olive iris]

What did you try? And what are your lighting settings for lighting tab?

[ionic smelt]

I will send a screenshot of that in a bit 🙂

[timber lichen]

After baking the lighting with all my lights in baked mode my character turned black how to fix this?

[viscid steeple]

Hey man first of all ur scene looks really good style wise really nicely painted.So lets get into the problem ,have u check if ur light sources are mixed as well and also have u tried shadow mask or indirect light?

[covert stirrup]

^ You can read about this topic in the Bakery manual. https://geom.io/bakery/wiki/index.php?title=Manual#Directional_mode
I'm not sure if the unity baker allows you to include normal maps in any way

[ionic smelt]

Here are my settings: https://gyazo.com/bc28976682fec8d5ca530812a041235b / https://gyazo.com/1990a4ec57f09300de3b4a7b8c44665c

[olive iris]

if its a moving character then you need light probes.

[olive iris]

for now just increase your texel density to a higher amount and see how much less noise you get. You can also turn on filtering to be manual.

[ionic smelt]

thank you I will try it out 🙂

[timber lichen]

does anybody know how to fix this issue?

https://cdn.discordapp.com/attachments/517108768933281843/839522541835255877/2021-05-05_11-21-55.mp4

[olive iris]

@timber lichen did you add reflection probes?

[timber lichen]

nope

this scene was standard 3D and i just updated to HDRP

i didnt have this issue before

and everything was more dark too

@olive iris

[olive iris]

@timber lichen It will not be the same if you upgraded to HDRP from another pipeline.

You just have to go through your checklist of troubleshooting. According to what you are doing.

And make sure you have setup everything correctly in accordance to HDRP.

But also in accordance to real time or baked. Etc.

[timber lichen]

@olive iris

see anything wrong here?

[olive iris]

@timber lichen Yeah you did not do any lighting it seems. No bake. No real time or mixed is on...etc

[distant lotus]

@olive iris I've tried adjusting many lighting parameters. Such as bias, bounce, cascades, etc. So far, nothing has worked. I'm trying to avoid going to HDRP, but I wonder if that'll be the only way to fix it.

[olive iris]

What about basic lighting? Did you generate uv map? Set it to static? Change the lighting mode?

[distant lotus]

The lights are realtime, so I didn't explore anything having to do with baked lighting.

All lights are static.

Most lights in URP don't generate shadows...at least in 2019.4. I have one active main light depending on time of day and that generates the shadow.

I've played with all settings on that light and on the smaller lights around the scene.

I also adjusted the basic light settings.

[olive iris]

@distant lotus Do you have overlapping lights and have you checked your pixel light count?

[olive iris]

Well if your using static light you need to bake it correctly, which you have not done.

[distant lotus]

I don't have any baked lighting.

Everything is realtime.

There is a temp light outside of the wall that is only for testing purposes currently, but when I turn that light off, it doesn't change the situation.

All other lights in the home can be turned on or off, so they're not baked. Just realtime.

The main light isn't baked, either. The main reason for that is because I don't know if it's gonna move later on.

And it'll be on or off depending on time of day.

Right now, performance is more than fine, so I'm not too concerned about it.

[fallow thicket]

Thank you! Very kind of you to say 🙂 I've since changed my lighting to mixed and started to bake with subtractive so that shadows are correctly baked from one asset to another. I'm finding even more issues with unitys default progressive mapper. My metals aren't baking nice at all either. I'm finding I might have to switch too bakery. I originally was baking with indirect and baked directional lights only.

[viscid steeple]

is that for a showcase or a game? also do u have a portfolio?

[charred wave]

any suggestions on masking the outter edges of my tiles, preferably fog?

without distorting the front view/path ahead

[fallow thicket]

It's for a game that I work on in my spare time. uh, yeah here's my port 😛 https://www.artstation.com/corshmell

[covert stirrup]

Highly recommend Bakery @fallow thicket 👌

[fallow thicket]

Funny you say that. I've been messing around with it for 2 hours now. The lighting is superior compared to Unity's default lighting.

[covert stirrup]

Haha that is a huge improvement yeah

They also have an implementation of volumetric lightmaps similar to what UE4 has

I’m not sure whether that’s included in the asset store version yet

[fallow thicket]

ah that's awesome

I'm doing some more tests in Unity default and finding I can almost get the results above again without bakery. I just can't seem to get the shadow to bake onto the statue

shadow is supposed to be baked onto him like this. I wonder why it's not. Is it even possible?

ah nevermind. I just found out that my amplify shader is whats causing the issue. Damn.

[covert stirrup]

I think bakery has some amplify shader things in it? I haven’t tried it personally

[viscid steeple]

Just checked ur portfolio really great stuff mani also worked on borderlands handsome edition so its good to see a fellow dev here!!!

[olive iris]

@fallow thicket You should be able to do anything Bakery can do just with Unity.

[fallow thicket]

Wooo! Fellow dev! That's awesome haha.

[steady galleon]

Hi all, googled this and found nothing helpful... Anyone out there know how to set "Contribute/Receive Global Illumination" on a renderer through the API? I'm instantiating prefabs using an editor tool I wrote; the input prefab has this option off, but I want to switch it on in the code just like I can with the other stuff:

                if (_renderer != null)
                {
                    // not clear if we can set GI options here
                    // _renderer.contributeGlobalIllumination = true;   <--- I made this up
                    _renderer.receiveShadows = true;
                    _renderer.shadowCastingMode = ShadowCastingMode.Off;
                    _renderer.lightProbeUsage = LightProbeUsage.Off;
                }

[austere canopy]

its just setting / reading the static flag for Contibute GI

its only for the editor since you can change the static flags at runtime
https://docs.unity3d.com/ScriptReference/GameObjectUtility.SetStaticEditorFlags.html

[steady galleon]

Cool, thanks, I only need it in the editor - thanks for the help @austere canopy !!

[ruby berry]

How come my lighting is like this?

This is after baking

[plucky sun]

does anybody use Bakery for lightmap ?

is it better than unity native GPU baker ?

@fallow thicket

the bakery scene feels dark, they don't provide scene with exposure.

like this

[fallow thicket]

I'm just using unity default light baking now

I'm getting same results compared to Bakery now 🙂

Unity's is easier to use also

[fallow thicket]

Yup, you're right 🙂

[plucky sun]

is Bakery waste money ?

😂

don't know where the lightmap baking code is ?

want to know how lightmap baker works

[reef quiver]

can you change the skybox thru an animation for better lightning?

[tired acorn]

so im having trouble working out baked lighting, currently i have set my imported models from blender to generate lightmap uvs, and the objects in my scene have been set to static, however when i generate lighting the end result is only meshes that i made in blender like a simple plane are seeming to be lit up

it works almost fine with real time lighting, but the issue i had there was the limit of 4 lights at one time so im trying to get baked lighting to work

this is what the road light map looks like so it seems like it should have light there

( update )

so if i take away the texture there is light

so its something wrong with the texture?

but it works fine with real time lighting

[olive iris]

you can increase pixel light limit to at least 8

[olive iris]

you can increase the lighting texture size or lightmap scale per object to cover more of of the lightmap, you can see it is not using the whole space.

[summer aspen]

You can also use your own lighting implementation for dynamic lighting. #763506960779051058 uses one. (to get around the limit)

[tired acorn]

im looking for those settings now @olive iris thank you

@summer aspen that sounds really interesting

[summer aspen]

This is the stream I saw showcasing it. https://youtu.be/O4N4s6BKNH0?t=3321 Shaders used are unlit, I think, so entire shadows and light implementation is uses in shader solution.

[tired acorn]

checking it out now 🙂

on a side note I worked out the original issue

[rapid galleon]

Hi, if I leave a point light by a static object without baking, will the light consume a lot of resources each frame even if there are no moving objects near it?

[olive iris]

Static light will bake a lightmap which is loaded once baked.
Real time lights will cast on going shadow per frame as the game runs.

[rapid galleon]

Thank you:)

[lost whale]

what is the recommended light mapper settings for optimization and good lighting? Is default settings alright or does it raise things not needed?

[fallow thicket]

Right now I think so yes. I can see the new rtx previewing thing being worth it but for me it's not needed. Baking with low quality settings first and waiting a couple minutes right now is fine for a preview

[olive iris]

depends on what you are doing

[junior holly]

I am looking for a performance-conscious way to light in-door environments. The environment is space/ moon-base, so I want bright lights on the ceiling, or maybe on the walls and the floor.
What's a good way to set up lighting in this scenario?
Thank you.

[olive iris]

😅

You should first figure out your pipeline.
Then you find references to guide you.
And then you light your scene the way you want it.
And then you come back asking for optimization advice as this is very contextual.

Avoid overlapping lights if your doing real time or mixed.
Keep your lightmap resolution within limits.
Do not use cast shadow on all lights.
Etc

[plucky sun]

is it possible to bake transparent to lightmap

?

[olive iris]

Technically...yes?

[plucky sun]

how ?

technically

@olive iris

[olive iris]

You go to #archived-shaders

[junior holly]

Thank you very much, this gives me enough to get started.

[olive iris]

@junior hollyLooking forward to seeing your work.

[timber plank]

Hello, I have a problem with my lighting. During the baking I loose some of my shadows that should be baked. I'm in HDRP, and I baked indirect only. My directional light is in mixed.
As soon as I clear my baked data, all shadows appears :/

to illustrate, on the left, it's before the bake, and on the right, after :/

[olive iris]

@timber plankWhat have you done so far and checked to make sure its correct settings?

[timber plank]

I baked in shadowmask mode, my directional light is setup in shadowmask / mixed, my shadowdistance is setup very far (for the test).
The gameobject is setup in static, and cast shadow is set to true.
I don't understand :/ normally, if we setup project to use shadowmask shadows of static object should be bake no?

Is it possible that there are a maximal shadows baked?

[olive iris]

It is possible you reached maximum pixel light amount that are overlapping though

So you would have to increase it but your using HDRP so should not be a problem.

It might be too much indirect lighting or too little texture resolution for your lightmaps etc

[timber plank]

Mmmmm, I did not know that the number of indirect can influence shadowmask.
I will investigate on points you highlight 🙂 thx!

[olive iris]

What happens is the amount of indirect lighting is making the shadow less visible. So, if you have changed it to be too much or you have too many lights that can sometimes be the reason for no shadow (even though its there).

Although in your case you have no shadow anywhere. At least in comparison to your images.

And your objects are darker. This can also happen if your object casting shadow is transparent or not normal material etc.

[fleet stag]

Can someone help me why my emission material doesn't reflect on the walls so It gets visible

I want it like the ceiling with this emission material to reflect the light on the wall

[simple latch]

If a material has emission how can I make like that effect that the light is around it? because right now it's only like emiting on itself

idk how to explain it

I want it to do as if it had bloom you know?

[olive iris]

Need to make sure everything is set to baked and things related to this

[olive iris]

find a reference image

[fleet stag]

@olive iris uhmm I think I managed to make it I just forgot to make the walls static

But my problem is that the light is not that strong

Any ways to increase how far it goes

Without making the scene more bright

[olive iris]

No, you use the emissive to get a bake lighting in terms of the local intensity. And then you can use a spot light to fill in the rest.

Hello beautiful people , do u know why this might happening ?

[olive iris]

Do you know what you tried or not tried to figure this out?

[pale walrus]

I have tried re-baking the lights many times

This didn't fix it

[tribal turret]

hmm guys I wanted to ask, Realtime GI or Baked GI? which one to go with? the map is a museum connected with pharaoh temple of sorts

Does anyone know the best way to change the emission color of an object without changing the material (which effects all objects with that material)? I have some lights I want to change when the stop light changes, but with multiple stoplights changing the color of just ONE of them is hard unless each one has it's own material.

[olive iris]

Well, rebaking is not the issue. What have you tried to troubleshoot and fix this? Have you adjusted lightmaps, have you spent time checking all the to do things for light baking etc.

[olive iris]

Why dont you just make a new material duplicate? You can also try to make prefabs. See if that works but I dont think it will.

[chilly crane]

hey there, i am new to baked lighting

anyone knows how i can get rid of these black squares appearing on my wall for some reason?

[olive iris]

Do you have similar shapes on the other side of the wall, such as shelf or picture frames?

[heavy mantle]

Hey I need some help with lighting on the forest level I've been building

Basically I'm between making the background layer be affected by the spotlights or not

[olive iris]

What is your question?

[heavy mantle]

if I should make the background layers be affected by the light or not

[jaunty kraken]

I think the background layers look good when they are effected by the light

[heavy mantle]

=) ok! Most people say this, they told me to also increase the frequency of lights

And make them all come from the same direction

[jaunty kraken]

Looks good 👍

[distant lotus]

@olive iris I've tried that already, but the goal was to avoid making a bunch of prefabs for each color and even then material changes will change on all objects using that material. I was hoping there was some way to change the color of the object like you can with 2D objects where you can just change the color of the individual sprite.

[distant lotus]

The only way I can think of this working is if I make a material for each color of a traffic light. Then change the material on the fly for each object. The materials are effectively the same, the difference is that the emission color is different.

[covert stirrup]

Way better with the uniform direction yeah

[olive iris]

You should generally have uniform direction. I agree

[chilly crane]

Nope

[olive iris]

What have you tried so far and what do you know about lighting?

[chilly crane]

I have tried to change some settings, tried to rebake the lightmaps with all lights in realtime (i know it sounds useless but there were still these squares).
I dont know much about baked lighting, cause i always refused to do it because it took so long and was always kinda buggy

[chilly crane]

i also tried disabling some lights

[gleaming plinth]

So I have an enclosed map and when I bake reflection probes the probes affect the map, which I don't want it to. How do you fix that?

[pliant totem]

Hi all !
I'm trying to bake my light on a URP project, but there is some trouble... My final rendering is absolutely disguting and I dont know why... Does anyone know why I got this problem ? And how can I fix it ?
Thank you 😄

[empty crane]

Hi, I'm looking for any tips or tutorials on a good beginner lighting workflow. I understand lighting concepts, but putting a light in the scene, waiting 10 minutes for it to bake just to see if it's at the right angle (or breaks other lights) clearly isn't scalable. I just don't know what process is, and most tutorials I've found explain 3-point lighting or other high-level concepts instead of workflows.

[pliant totem]

@empty crane use realtime to choose where to place your light. When you appreciate result, go back to baked/mixed and then : bake your light

[pliant totem]

Does anyone got an answers ? 🙂

[empty crane]

Heh, maybe I'm overthinking it. What about baked only lights like area lights?

[pliant totem]

Same, do your test with realtime, and then bake the light

[empty crane]

Unless I'm missing something, area lights don't contribute any light to the scene until you bake. In my inspector it says "Area (baked only)"

[empty crane]

Area lights are giving me a lot of trouble in particular. This is a small rectangular area light with default settings, 2.8 units above the ground. I'm expecting a rectangular soft source, but I'm getting a perfect sphere with hard edges. What am I missing?

[olive iris]

increase emissive value

[olive iris]

Keep low settings and then increase later.

[olive iris]

What did you try?

[ornate mist]

can anyone tell me why lighting in my game seems to have no effect at all? This spotlight is doing ntohing

[fluid epoch]

pardon but why the hell is scene in some parts black and others it shows the skybox properly

it drives me crazy

im using unity 2021.2

like im in scene view now, i move it slightly

and it goes constantly between black and skybox

[olive iris]

try increasing intensity

[olive iris]

make a video showing this

[fluid epoch]

i mean its not something that will make a big difference

imagine paning the camera, and just that makes it flick between the two views (in scene view)

maybe im doing something wrong since im getting used to HDRP but i doubt that is the case judging by my colleagues that say this never happens to them

could it be a mesh or something i wonder hmm

[ornate mist]

@olive iris no effect

still looking for help as to why my lighting is having no effect in my game

[olive iris]

select and object. Press F. And see if it still happens.

[olive iris]

how does it look like when there is no light?
What are your settings in lighting tab?

[ornate mist]

i think i figured it out

my pixel light count under settings was at 2

i increased it to 100

[olive iris]

Yes, that would be a common reason if you are not using HDRP

[fluid epoch]

yeap

oh wait

i have turned off scene lightning just now cause i was testing stuff

a moment

nah still happens

[olive iris]

Realtime or baking?

[fluid epoch]

@olive iris baked lightning (but that shouldnt affect scene lightning should it?)

[olive iris]

It would if you did not set objects to static on top right.

[fluid epoch]

yea you are right, but that shouldnt affect Scene lightning, it would affect the color of said object / lightmap

[olive iris]

Also, are your objects 2d?

[fluid epoch]

3d

[olive iris]

Did you restart unity and computer?

[fluid epoch]

yea this is ongoing for a month but i just started to handle it cause i was jumping (with other projects) in between versions for some time

restart - shutdown - disk change you name it ( it has been a lively month )

i am not denying this could be due to something i am not familiar with like a lightning setting etc

but this very same scene quite litteraly on unity 2019 per example is just fine

if i bake or whatnot

but in 2021 it will have or even in other scenes when baking ill face the same blackness

probably also the fact i use hdrp in the project im showing

instead of hte urp i have been messing around in 2019 and etc

[timber lichen]

I'm in HDRP 2021.1.7f1

Adding a new point light, and setting any radius above 0.42 and activating shadows results in this......anyone know why?

[fluid epoch]

did you figure out why?

[timber lichen]

not yet, going to start a brand new project and test it...

[glossy hemlock]

Why is the shading on a primitive sphere so odd? Notice the incredibly black dark spots and a bit of odd lines near the top of the sphere? This is just a primitive sphere and a default directional light on a new scene. What can I do to make this lighting smoother? URP

Other issues on a flat, standard material cube:

[steady galleon]

@glossy hemlock what program is that? I don't recognise the interface in your first screenshot... Also, are you using baked lightmaps? If yes and you're in the unity editor, what does the image look like when you switch to the Texel Validity view? Just thinking out loud really.

[glossy hemlock]

That's the thing I'm making, it's just a way of viewing materials to use elsewhere. I don't think I've done any baked lightmaps unless they're on by default, I didn't change anything.

I'm not sure what the texel validity view is, but I'll figure it out ll. I'll have to check it out when I'm back in the office Monday

[idle axle]

My unity keeps crashing when I'm trying to bake my lighting, are there any solutions?

[steady galleon]

@idle axle that's weird, I'm finding exactly the same problem for the first time today, found it on 2020.3.6 and 2020.3.8, in both cases I can bake at 128 Texels/Unit but at 160 or higher (I usually do 512) it hangs and I have to kill it from the Task Manager. I haven't tried CPU because it would take all day, I'm baking on an RTX 2080 Ti GPU. tl;dr, sorry, no solution, but will post if I find one.

[idle axle]

eh, I just started a new project.

[lost whale]

There's no overlapping UVS and this is happening when I light up a interior built in pro tools any ideas how to fix?

[silk light]

does anyone know where to find example scenes demonstrating real-time lighting (free or paid)

https://assetstore.unity.com/packages/essentials/tutorial-projects/the-courtyard-49377 this is all i've found ... doesn't even have to be this fancy or HDRP, just looking to learn some basic lighting set ups

for real time... don't care about baking or lightmapping

[lilac palm]

hi, do you know any good good courses or recources for realistic environment creation/ lignting for unity, there are ton of unreal but not so many in unity, i wonder why

[olive iris]

@silk lighthttps://www.youtube.com/watch?v=CLHo8eU26qI

@silk lighthttps://www.youtube.com/watch?v=Pn4Q_WRYxec

If you learn this then real time should be fairly easy. The key difference is little if your learning the basic.

Although, I might create a new one for HDRP both baked and real time version of small environment I found. A quick course.

[terse dome]

sup everyone! I am getting some artifcating in my light bakes, not sure how to most efficiently troubleshoot this, anyone have any suggestions?

[silk light]

I didn't ask about courses, I specifically asked about example projects that I can download or buy.

[olive iris]

ill try and make one when I get that far.

@silk lightDid you try this? Not sure if it is real time or not though. I can not remember. https://assetstore.unity.com/packages/3d/environments/unityjapanoffice-152800

[silk light]

@olive iris this is what i'm looking for, didn't know this category exists. Thank you very much. :)

[olive iris]

I know a few more other places but...top secret for now.

[rugged oyster]

Is there any way to remove these little white lines?

[glad moth]

Hi, Im having an issue with my emmisive materials on my windows. All windows you see in the screenshot have the same emmisive texture. However the ones on the right don't seem to be emissive at all. Its something to do with my directional light but I like the angle I have my light at so I dont really want to change it. Anybody know how to fix this ?

[copper violet]

does anyone know how to increase the range of realtime shadows? i have a camer setup very far away from the player but i would like to see the shadows casting. this only works when im close to the character. i cant find any videos on this fix

[summer aspen]

@copper violet Don't cross-post

[copper violet]

@summer aspen i don';t know where to post it and no one is helping me

[summer aspen]

@copper violet Pick one relevant channel. Then ask again later when the other part of the world doesn't sleep.

[copper violet]

@summer aspen is this the right channel? there is nop channel for shadows

[summer aspen]

Yes, it's lighting. You can find shadow settings in lighting settings. Play around with cascades. There are also resources pinned here.

Cascades are in quality settings for default pipeline and with lighting settings on the URP asset in URP

[orchid solar]

There's a huge shadow body for no reason, theres a light pointing directly there

This is what it looks like from above. The lamp has castShadows false.

[olive iris]

What is it specifically?

[olive iris]

create another emissive and make it stronger?

[olive iris]

Try making the radius of the cone smaller and see what happens.

[rugged oyster]

It was the light reflecting on the surface of the object but I fixed it with anti-aliasing

[olive iris]

Sounds right.

[timber lichen]

https://cdn.discordapp.com/attachments/497874004401586176/844410296788975656/2021-05-18_23-04-28.mp4

anybody know how to stop the light from changing like that ?

[olive iris]

Reflections

[frosty glacier]

do i need to change GI from lightmaps to lightprobes? Or do i need to set my floor's and other objects' GI to lightprobes?

[olive iris]

What is your question and what are you trying to do?

[frosty glacier]

i'm trying to make good lighting in my scene

and i decided to add this small light sources

[olive iris]

What is good lighting?

[frosty glacier]

which is basically just cylinder with emission

[frosty glacier]

wait a sec

[olive iris]

Emission needs objects around it set to bake as in static for it to show up.

[frosty glacier]

that is good lighting

[frosty glacier]

in the previous case I made a mistake while modeling

my baking process takes over an hour at less than 1 million rays

so I won't tell you about the results soon

[olive iris]

Yes, you would have to learn a few things I imagine.

Which pipeline is this?

[frosty glacier]

built-in. But im pretty sure that urp would be better for performance, but not for graphics

[olive iris]

Might teach you a few things maybe? https://www.youtube.com/watch?v=CLHo8eU26qI

[timber lichen]

@olive iris

[frosty glacier]

thanks, i will see this later

[timber lichen]

idk which ones to uncheck i tried everything and it doesnt work

[olive iris]

You should turn on reflection settings and add reflections probes and see if that fixes it after you bake it

[timber lichen]

do i bake the walls @olive iris

[olive iris]

everything yeah. try it out

[timber lichen]

im scared

[olive iris]

Should be enough just to bake reflection

So you can click bake on reflection itself

[timber lichen]

just one reflection probe ?

[timber lichen]

@olive iris honestly i feel like this is not a baking issue

[timber lichen]

it was this

[olive iris]

Yeah that would be one of the other things to setup in HDRP

[timber lichen]

getting the same issue with in game lights now

@olive iris

🤷‍♂️

[main wolf]

Are you using forward or univeral pipeline?
In frp and urp , there's a limit on maximum realtime pixel light (iirc 4 in frp & 8 in urp)

[timber lichen]

im using HDRP

bu its all good now im just gonna use a flashlight with dim directional light and a fog

[olive iris]

That....is overkill of lights.

[unborn hamlet]

Hi, does someone know what causes these shadow artefacts? I tried adjusting smoothing groups and shadow quality settings. Is it maybe because the mes is too lowpoly?

[frosty glacier]

Do normals work when using area light and emission? if you turn off the lighting in the scene, the surface relief is visible, but after baking the light, there is no relief

[unborn hamlet]

@frosty glacier Baked light is not really an option, since i'm experimenting with mesh deformation

thanks anyways mate

[frosty glacier]

No I mean

I'm trying to make textures like In Karlson 3D

normals are used there

but I can't see them

I think this is due to the fact that I use area light and emission

[unborn hamlet]

Oh ok I'll read into that thank you

[frosty glacier]

that was my problem but okay lol

[covert stirrup]

Look into the directional mode @frosty glacier https://docs.unity3d.com/Manual/LightmappingDirectional.html

It's also explained in the Bakery documentation https://geom.io/bakery/wiki/index.php?title=Manual#Directional_mode

[frosty glacier]

Oh thank you!!

So I should choose

Or performance or graphics

[unborn hamlet]

Ok thank you ver much 👍

[frosty glacier]

Use light probes

[frosty glacier]

still not what i want

[olive iris]

did you set floor to static?

[frosty glacier]

yep

but somewhere i can see small light

it is actually funny

[olive iris]

Did you reduce other lights

[mental pulsar]

Looking a bit dark, what should i add?

[frosty glacier]

Yep

[frosty glacier]

Ao

[mental pulsar]

Post-processing AO?

or materials

@frosty glacier

[frosty glacier]

I think in lightmap settings

It should be enough

But if u want u can add post-processing ao

And materials ao is good too

[mental pulsar]

i have those on 🙂

[frosty glacier]

You can choose all of it

And it would be the best graphics (with proper settings)

But not the best performance, I think

At least with post-processing

[mental pulsar]

Lightmap mode in project settings?

[frosty glacier]

Lighting settings in the scene

[mental pulsar]

looks like my emission value was too low XD

[olive iris]

dont use emission level...its not meant to brighten your environment like that...

[mental pulsar]

@olive iris I was using 1200 - 1700 intensity for directional lighting. What should i replace it with if i dont use higher emission?

[olive iris]

You need to tweak your ambient or sky and the other parts of the lighting such as indirect lighting.

Try this workflow out and see if it helps. https://www.youtube.com/watch?v=CLHo8eU26qI

[mental pulsar]

@olive iris ohh, i am using sky and fog volume. I adjusted the Lux value does seem to have affect on lighting

[orchid solar]

After I generated lightmap UV's my lighting builds take forever to prepare (literally, it doesn't end)

There are errors that say 6 out of 60 components have non-finite values. What does this mean and how do i fix it?

[olive iris]

@orchid solarWhat links did you search online for using these keywords?

[main laurel]

https://youtu.be/Atg-GeWp9Eo Hey guys I've been running into this issue where the Unity skybox randomly renders black splotches on the Oculus Quest. (See Video) Any ideas on how to fix it?

[orchid solar]

@olive iris I looked at a bunch, they say it's a bug. Some talk about something called Pro Builder. I don't even know what that is

[olive iris]

@orchid solarits the modeling addon in Unity

If you are not using it to create your 3D you can remove it.

[drifting star]

guys how is it that when you have a light on a to hit onto of a dark mat it doesnt show any light, but it does when the mat is a lighter color. Anyway to fix this?

[viscid steeple]

I have a problem with raytracing emissive materials do not show bright as on baked illumination and ssgi, doesnt rraytracing support emmision?

[olive iris]

what render pipeline?

Also does any of this help? https://forum.unity.com/threads/raytracing-gi-and-emissive-material.817998/

[viscid steeple]

@olive iris its HDRP raytracing only exist in HDRP if im not wrong

[olive iris]

try the forum link and dig around a bit

[viscid steeple]

I did and the person providing the help doesnt show their emission materials and all those settings dont help i already saw that and tried it with no success

[safe pewter]

Having trouble baking. I keep getting out of system memory errors but I'm nowhere near my max memory usage (I have 32GB)

My scene is pretty small.

That's a default cube for scale.

My objects are marked as Contribute GI in the static flags. My lighting settings are default. My directional light is set to mixed

I've tried:
Changing light map size

Changing baking device (from GPU to CPU)

Changing light map resolution

Also, during baking, there's a timer for Global Illumination and from what I can tell, it just increases infinitely. I waited 30 minutes for it to do something and it just kept increasing.

I have a i7 10875h (8 core 16 thread CPU @ 2.3GHz base clock and 4.3 boost clock) and an RTX 2080 Super with Max-Q Design GPU

[lunar harbor]

i changed my project to HDRP so that i could make decals and now it's doing a weird thing where, if i turn my camera to face a certain way it lights everything up

[drifting cliff]

how do you make the background black in the HDRP pipeline? Trying to make it dark and I can't figure out how to do it in this setting

[sour plinth]

guys i have two point light in my scene but when one lights intensity is more than the other one suddenly the lower intensity light effect is dissappering why ?

[safe pewter]

Still need help!

[sour sinew]

I'm assuming this is a quirk with URP that I don't understand yet since this is my first time using it, but setting my scenes' environment lighting to Skybox causes all of my objects that use the default Lit shader to produce a bright blue glow and I can't for the life of me figure out why

I also can't seem to get Specular maps to work, as they render the entire surface they work on white as seen on the Earth there

[vast kelp]

Hey guys im pretty new to lighting and keep running into some problems. Whenever I finally get a good lightmap bake and restart unity it 1) Opens up & looks like it discarded the lightmap or 2) Has a "size overflow in allocator" error.
Can someone help me out? I use the lowest settings for lightmapping on a pretty large open world?

[olive iris]

Check your GI cache.?

[olive iris]

Exposure settings?

[olive iris]

Light pixel amount settings?

[olive iris]

This one is a hard one. I cant remember. You best turn off other softwares, antivirus and such. And start with turning off things and have low setting on one thing at a time. And kind of narrow it down.

[copper granite]

Hello everyone, I have wasted quite a couple hours trying to fix this problem. Let me explain. I'm baking shadows however they are of low quality, but the shadow settings are set to highest resolution. Some notes:
-Reducing scale of ground improves the quality but that was just a partial fix
-Small objects suffer from really low quality
-Large objects are close to expected good quality
-Generating lightmap uvs does not change a single thing
-There are no such issues in realtime shadows

Here is example of large vs small flower

[copper granite]

nvm i fixed the problem now i'll go sleep :/

[olive iris]

which was?

[sage slate]

hi, i have spent too much hour to resolve those lightmap error, i've tried everything that i have found on internet, but nothing, the env is modular, we didn't have UV map for lightmap, but we have generated them directly in unity, have you any tips, to fix that?

[vast kelp]

I just cleared it before baking the lightmap

[olive iris]

You need to increase lightmap resolution among many things.

[olive iris]

This might help https://www.youtube.com/watch?v=OetZhBc2A98

[copper granite]

I bumped up the lightmap resolution to large value like 100

Wait I don't get it why do I needed large lightmap resolution for small objects tf

[sage slate]

OK THX I TRY

shitti caps lock

[safe pewter]

I've tried the lowest settings possible. I have no anti-virus enabled, the only thing open is discord and unity.

It still happens.

[olive iris]

try a new scene or project.

[silk lichen]

I have two directional lights, one for the environment (baked) and one for the characters (realtime), but my realtime doesnt cast characters shadows

[mystic dew]

with baking mode are you using?
Try to use mixed light + shadowmask baking mode

[silk lichen]

do I turn my baked light into mixed + shadowmask ?

[mystic dew]

yea, just delete second light. and make first one as mixed light

[silk lichen]

I had one light before, but I wanted to render the characters a bit different from the environment, so for that I added a white realtime directional light, and left a baked yellow tinted light for the environment

I guess instead of adding a new light for this case, I better look into shaders instead

I will revert back to one light setup

[sage slate]

i dont know why, but it doesnt work, my modular wall have seam, so we have decided to create one mesh with lightmap uvs and now we have fixed the error, but i'll want to create env with modular asset, so how can i do it, with a good optimization, have you any tutorial link?

[quiet surge]

I wanted to make an area light, but it doesnt work. The whole area is set to static. I tried it to bake it manually too, but still doesnt work. Even with itensity and range up to 5k. I also tried to set the light to static. Im out of ideas

[quiet surge]

Did you fixxed it? I have the same issue

[pale rampart]

No I don't think I was. That project was cancelled a while ago now

[thorn yoke]

Woahh that looks cool!

[silk lichen]

thank you 😁

[thorn yoke]

what are you making?

[silk lichen]

its kinda early to say lol, but its a story driven game for now, not sure if and what kind of combat it would have so cant say its action story driven you know

[quiet surge]

._.

[timber lichen]

So I'm using a concrete texture, and I can't seem to figure out how to get rid of the reflections and make the texture more visible. You can barely see it at some angles

This is how I want it to be like.

You can see the entire wall brightens up because of sunlight

But in my one there are multiple different areas

[tough flower]

Is it possible to make my scene’s lighting somewhat more like the prefab editing mode?

https://streamable.com/3vouf4

Cause rn i have a directional light above

But id like everything to lighten up more smoothly

[timber lichen]

I need a lighting storm shader or a flashing one

[trim pine]

so i tried baking light into a vr scene in unity and it's complaining about overlapping uvs, is that bad? like how bad is that?

[limber granite]

Hey, what am I doing wrong?
I am making a lightmap for mobile game level, but do matter what I bake, it's always way above 300 MB (on low-medium settings - I can go up to 1 GB on high). It's unacceptable of course for mobile builds.

What can I do to make lightmaps smaller and not look like hot garbage?

[indigo knot]

My lighting seems fucked when loading a new scene.
Basicly I have 2 scenes.
if I press play in Scene B everything looks good.
but if I am in Scene A and I want to load to Scene B the lighting is fucked.
Anyone maybe know a reason?
also it may be important to know that scene A doesnt contain any lightsource or anything, its just the Menu

I fixed it myself

For anyone with the same problem :
Check for both of your scenes the LightingData.
I simply removed the LightingData from scene A and gave scene A the LightingData from Scene B.

This way both scenes should have the same lighting data and yes, it worked.

[frank grove]

I need some help. The left picture is with URP and the right one with the old standard one. How can I achieve similar results to the standard pipeline ?

[simple latch]

not sure if this is the right channel but do you see that ladder?? why is it kinda lagging? i made sure it isnt duplicated or anything and it might have to do with the lights

[tender oak]

Hii, so I downloaded a custom Skybox from the Unity Asset Store and now I got bloom enabled in my Season but it the Sun from the Custom Sky Box is extremly bright and I just want to remove it or dim the light from it. How can I do that?

[austere canopy]

looks like Z fighting of overlapping polygons.

[manic plank]

anybody know why my baked lighting would come out like this?

the light is a emissive material and theyre recessed around the ceiling

[covert stirrup]

How bad it is depends on how the lightmap looks. If it doesn't have issues, you don't need to worry

[trim pine]

if i understand correctly the issue is that if you have overlapping UV's on a single texture you'll get random patches of light passing on the material

[covert stirrup]

If you have overlapping UVs for the lightmap, unity will write baked lighting to those pixels multiple times, resulting in artefacts

If you check 'generate lightmaps' on your mesh, unity will create new UVs in a new UV set and use those for lightmapping

[trim pine]

so i don't have to go back and make an entire train fit on a 1024x1024 texture?

[covert stirrup]

Unity will do the packing for you, but it's a tradeoff between texture memory and lighting quality

[iron dome]

hello. I am messing around with the lighting in URP 3d and real time shadow colour doesnt change the colour of shadows or do anything at all

also i notice that the editor view lighting is different during runtime compared to editor only veiw

Editor (not runtime)

while playing

[placid magnet]

Hey I'm working something isometric like starcraft style with empty space / void under the map so you can see it when the map ends

the skybox only looks good when the camera is set to ortho

normal 3d makes the skybox super low resolution

[empty glen]

Hey all! Does anyone have an idea what could be going on here? On every model I import (2021.1.3f1), there seems to be this "hard edges" rendering. I am 100% sure the mesh is soft edges (I've reimported the model back into my modeling package). When I import it into another project (2020.2.1f1), that issue is not present (import settings the same in both). So I am thinking it must be something in the lighting in this specific project. It shows up in-game too, weirdly as well, when I rotate the camera these dark triangles show up and disappear.

also the closer I get to the model, the more intense these dark triangles get, from a really far away camera they pretty much disappear

[wicked orchid]

Does moving a realtime directional light during runtime have a costly tax on performance?

[empty glen]

Appears to be the URP NewScreenSpaceAmbient Occlusion causing this, changing it to Depth Normals seems to have fixed it 😄

[burnt kindle]

Hi, i have this problem with the shadows on the terrain. Everything look correct in the setting. Does anyone have any idea how to fix this problem? In the scene i have multiple terrain, each terrain is 512x512

[spice quail]

can anyone explain the meaning of baking lights and why we should use it currently when i bake my lights everything goes black

[copper granite]

Maybe. Test it using profiler?

[wicked orchid]

I am trying just that. I'm noticing the EditorLoop doesn't appear to like it (tail end is pausing rotation of the directional light)

[copper granite]

You can run the profiler on the standalone build in that case

[wicked orchid]

Even in that case, the EditorLoop still appears to be the culprit

Drops off a cliff (in a good way) when I pause the rotation behavior

[copper granite]

Interesting, this means the overhead isn't much ? The editor loop's ms would be completely eliminated on a standalone. However I recommend u looking at the variables in other areas like the player loop to confirm ur analysis.

[wicked orchid]

One can hope

I'll have to test in standalone build soon

[copper granite]

Yeah good luck man👍

[copper granite]

Also looking at the graphs it doesn't seem u have much perf issues(200fps).So why bother?

[wicked orchid]

Well, I turned off all the other profile stats just to highlight this one... FPS gets closer to 60

[mental pulsar]

Hi, can i get some tips to improve this scene's lighting?

[gaunt sand]

help I have hdrp and a directional light but the light made this

[copper granite]

[copper granite]

Ahh ic now👍

[safe pewter]

I'm trying to lightmap this model of a bedroom I found in Unity. Here's what it looks like in eevee with baked irradiance/lighting.

I can't even get close in Unity

I've tried every combination of lightmap UV settings (generating them via the model import window) and tried different lightmap settings (higher texel resolution, higher resolution in general (4096), higher lightmap quality (currently on high)

Light probes are in the scene

[safe pewter]

Hmm. Seems like Unity wasn't actually generating lightmap UVs

maybe a bug with the .blend importer? Exporting as FBX and then generating lightmaps on that worked.

[safe pewter]

still not looking great

half of the time it breaks or otherwise refuses to bake

this seems to be unity's new favourite error message to throw at me now

i cant really put into words how much I hate Unity's lightmapper.

I've never had it work properly for me.

[lunar pollen]

is this seriously what unity is giving us for "realtime gi" in hdrp?

ue5 just released lumen into early access along with a system that basically decimates geometry in real time to allow for hundreds of millions of triangles at once, and unities render pipeline thats meant to rival ue with high end graphics just does this

[willow patio]

Is that the recent screen space GI?

[lunar pollen]

im on 2021.2, with realtime gi enabled

[willow patio]

So is this Enlighten?

[lunar pollen]

supposedly. i really hope theres just a bug in the alpha

cause if this is end result im gonna have to switch to ue

which sucks cause my project has been in development for 1.5 years now

[willow patio]

Realtime GI in the Lighting settings is Enlighten. It's old but Unity doesn't have much of an alternative.

Basically there are 3 options for realtime or pseudo-realtime GI in HDRP

Enlighten, screen space GI, and raytracing.

[lunar pollen]

why dont they just develop their own? like ue did with lumen

[willow patio]

Because it's not easy

And UE5's new graphics features require some hefty system specs

[lunar pollen]

its not easy, but unity is the most used game engine out of all of them

[willow patio]

Unity is supposedly developing a new GI solution but it's going to be a long time before we hear anything about it.

[lunar pollen]

thank god

as long as we get it eventually, thats all i really care about

hopefully they start working on a knock off nanite too

[willow patio]

Enlighten was removed from the engine because they were planning on releasing their own realtime GI solution, but then added Enlighten back when they realized it's gonna be a long time before their own is production ready, or anywhere close to it.

UE5's new stuff is awesome and I hope Unity is able to pull off something similar even if it takes a while. I hope it becomes industry standard.

[lunar pollen]

the thing is it looks better in built in render pipeline. its so splotchy in hdrp

[willow patio]

Because of the crazy chip shortage, UE5's new stuff is basically going to be limited to movies and realtime animations for a little while.

That gives Unity and other developers some time to figure out their crap.

[lunar pollen]

the thing is it doesnt matter at that point

cause almost everyone will have an RTX card

anything non rtx will be considered low end

this wouldnt be so much of a big deal if there was a way to make light map pixels not stretch with scale

[stark temple]

That's how UV mapping works

you need to create your own models if you want to do lightmapping

[lunar pollen]

i did create my own models

[stark temple]

Don't scale them

[lunar pollen]

working on an underground tunnel lighting scene, stretching the tracks and increasing tiling is the best way to keep vert count down

my project has custom mapping, and i dont want people to have to know how to edit models and their uvs just to use my assets

[stark temple]

Then make the model longer in your modelling package

[lunar pollen]

^

[stark temple]

Or generate the lightmap uvs yourself

which is going to make a new model, really I wouldn't be worrying about the vertcount

[willow patio]

yeah I would just provide multiple tunnel segments of varying lengths

don't need to bother the user with adjusting tiling that way

[stark temple]

Many options, just scaling the models and doing nothing is one of the only things you cannot do 😛

[lunar pollen]

im trying to make things as convenient as possible for the people using the system, but i guess i dont really have much of a choice then

welp, thanks for the recommendations guys

[willow patio]

multiple tunnel length options to choose from is most convenient imo, that's what people have come to expect. If I purchased a unity package and was only given one tunnel length to choose from and had to scale it myself to change the length, I would be unhappy.

[stark temple]

Scaling non-uniformly is one of the easiest ways to break batching, which probably doesn't really matter in this case, but generally scaling things is an easy way to have performance issues. Sad, but that's one of the things you put up with

[lunar pollen]

iirc, srp batcher didnt rely on scale?

or am i wrong

[stark temple]

I honestly have no idea about the SRP Batcher's constraints

would have to check the frame debugger to find out. If that's gone away for SRPs that'd be cool, though not that that helps asset developers if they are also making content for the built-in pipeline.

[timber lichen]

only for "realistic" games. Stylized stuff won't really need rtx for light bouncing or anything except for the DLSS tech.

[lunar pollen]

they wont "need" it, but it will be the norm and standard

for gpus going into the future

there will never be a new gpu released that does not support rtx

unless its a gpu created for mining

[uncut dune]

hey idk if its about lighning tho but....I made a fog in my unity but it make problems

[lunar pollen]

does realtime GI depend on lightmap uvs?

[wicked orchid]

I'm in HDRP, any reason my directional light would look different in build vs in editor?

[safe pewter]

Why is part of my mesh just straight up not getting any baked lighting on it?

It's part of the same mesh (the walls) but they're just not getting any baked lighting on them

[rotund bronze]

Im not sure if this is the place to ask but it feels most relevant.

In my game, I have two variations of a level, lets say one intact and one destroyed, in a single scene. They can be toggled between being active or not active with a button press, to switch between the two worlds.

I need to have baked lighting in both scenes, and be able to switch between two baked lightmaps at runtime, whenever the played switches worlds.

I have found tutorials doing it with a scene, but the scene in the demonstrations all are the same, and mine are geometrically different.

Is this even possible what im trying to achieve, and if so, can anyone point me in the right direction.

An example to what im trying to achieve is like the following from titanfall 2, possible spoilers || The time travel section , where the player needs to switch between worlds to fight enemies and move through the levels ||

Hi ! Is there a way to light partially with an HDRI but not rendering it as a background ?

[lapis aurora]

How does one change the opacity of a 3D object without modifying the properties of its material? Unity 2018.1

[covert stirrup]

There is no other way to set the opacity than the material. What is it that you need @lapis aurora?

[slow cliff]

if your doing 2d lighting it often doesnt need to be that good. just make a bunch of white lines or a white sphere and change the color and alpha on it. and put it on a layer over what you want

[lapis aurora]

Preview laying down an object

[olive iris]

No, you just expect it to be drag and drop.

[olive iris]

Dont need that many light probes

[olive iris]

If nothing is moving you dont really need realtime GI though.

[safe pewter]

I don't think they matter anyway. Disabling them changed nothing.

[olive iris]

Of course, you need to light it all.

[safe pewter]

I already tried. You can see the results. Parts of the mesh weren't being given any baked lighting and I'm not in the mood anymore to fight with Unity's lightmapping

[lunar pollen]

No, its just a bug. Unity is fixing it in the next alpha

[lunar pollen]

You dont understand the context for me needing realtime gi

[olive iris]

Do explain.

[lunar pollen]

i have custom mapping in my project. lightmaps are huge, and increase loading times

not worth using on the smallest details

and i have plently of headroom for cpu performance either way, since im in hdrp targeting mid-high end pcs

does that work for you?

[olive iris]

You can always hire me to do the lighting. If this is an asset your planning on selling.

[lunar pollen]

Why would i hire you when i literally said its a bug they fixed for the next alpha

Also, im not making assets. Ive created all the systems for my own personal project

[safe fox]

👌

[meager olive]

is there a way to do this in unity? I dont know how to search this on internet. It's like spot light in unity but without lighting the middle

[covert stirrup]

Try light cookes @meager olive https://docs.unity3d.com/560/Documentation/Manual/HOWTO-LightCookie.html

[meager olive]

Thanks let me see

Damn it doesnt work with urp 😦

[gilded cloak]

could anyone recommend what to change here? kind of a newbie when it comes to lighting, just making a simple tower defense game. when i tried to generate lights it said out of memory...though its not a very complex scene

[copper granite]

try disabling filtering

or reduce lightmap size

[copper granite]

https://cdn.discordapp.com/attachments/85593628650504192/849936414584995850/2021-06-03_14-29-16.mp4

why is the plane's texel size not decreasing as i increase the lightmap resolution, the other object works as intended.

the larger the ground is, the worse it gets, and the max lightmap size of 4096 isnt enough to fix it , so i guess the issue lies somewhere else, but its weird for a default unity plane object.

due to this the shadow quality is pretty bad :/

[indigo knot]

Does URP already come with inbuild Ambient Occlusion?
I've read that I "could" add it manually by adding a new Renderer Feature, but its not there for me.

Hey guys, I don't really know where to put this message, but I guess that this channel fits the best. I was getting into figuring out lighting in my game (HDRP pipeline) because I had all of my lights realtime and unless your computer was a gaming rig you could not run it. I decided to try and do some mixed lighting and baking, and in certain areas of the world, the lighting goes really wierd. Does anyone know why this is? I am sorry if I anger any of you lighting veterans, I know little to nothing about the topic.

Before

I will greatly appreciate any help or advice anyone can offer.

[lunar pollen]

mark your stuff as static

[tall verge]

Does ambient occlusion have an effect if lighting is set to nondirectional? Also, I'm having an issue where some spots seem to be reversed in light direction when directional lighting is checked, anyone know how to fix it?

[compact rock]

@lunar pollen so if I mark the static stuff as static it will fix the lighting or..?

Honesty Brackey's video is really good 🙂

Hey so I recently attempted to bake my lightmap using Progressive GPU, and after a few seconds of it completing certain "jobs" it finally started baking. However whenever it started baking Unity just becomes unresponsive? I am using Unity 2019.4.8f1, and below are my settings. I recently switched over to a 3080 ti and I have 16G of DDR4 Ram (if thats important) yet the same thing?
https://gyazo.com/aac5f9c2cf3933613ea197f71153b857

Ohhh duudee thank you so much, I'll definitely check it out

[dense dirge]

Better global illumination, bounce lighting

https://youtu.be/KJ4fl-KBDR8

https://youtu.be/okYhs6kQ0xw

Might help

[fast pendant]

Couldn't you achieve this with a tiny invisible shadow-casting object placed very close to the spotlight source?

[meager olive]

honestly havent thought of that, will give it a try, it'll probably work

thanks dude

[fast pendant]

I'd love to know if it does! I'm kinda making assumptions about how the spotlights work but I've def used invisible shadow casters before with success

[frank hound]

is it possible to turn of global illumination?

it's only a bit of cpu time, but not needing GI for my game I'd love to even get rid of that bit

[olive iris]

Should be a setting in lighting settings?

[olive iris]

Put it in a mesh that has this shape so you cast shadow where it is no light

[meager olive]

That'd also work yeah, thank you

[frosty glacier]

does area light effect normal maps?

[frank hound]

@olive iris tested pretty much everything in lighting settings. Definitely can't be turned off there. Maybe it's just in editor though?

also I haven't found anything useful in the docs for the profiler (global illumination page)

[inner seal]

hi! simple question that i cant find any answer to online: how do i have the upper cube cast shadows on the cube below?

[frosty glacier]

Cast shadows

[frosty glacier]

You need to change cast shadows property in mesh renderer of the upper cube

[inner seal]

this?

[inner seal]

if that is what you meant, that is always on by default and i checked to make sure they were on

[inner seal]

(i solved it)

[olive iris]

Maybe what you want is not to turn off the GI which I know is under lighting setting in at least one of the pipelines.

[proper osprey]

Hey :) Im trying to develop a game based on the artstyle and lighting of Playdead Inside. Im using the URP but everytime to try and light up a scene it looks bland and bad. I dont really know how the lighting system in unity works :/ can someone help me? Thanks! :)

Anyone happen to know why this is happening?

i found a form hidden and says that it seems lightmaps of my kind don't have webgl support

[proper osprey]

Hm I would advice you to try various types of lightmapping then

[frosty glacier]

how to fix this?

and why my lightmaps are red?

[frosty glacier]

Please, someone

[timber lichen]

I'm having a problem where a shader won't receive shadows from any other light source in the scene apart from one directional light. Other shaders recieve the shadow of the cube fine, so I'm slightly confused as to why its doing what it is... (please @ me if you can help)

These are the only differences between the two passes

and yet from what I can tell the first pass (base) allows the shader to recieve shadows

[timber lichen]

^what it should be (using the example of a window and spot light

what it is

The shader is fine casting shadows but doesnt like recieving them

[little tree]

i had a couple questions, as I am new, but if I have a map with a ton of objects whats the best way to create a lightmap / improve lighting

Hello, I'm trying to make my volumetric lighting here stronger and the sliders here don't seem to be doing much at all. I can see that there is volumetric light but it's not very noticeable at all.

That's my settings for the directional light. Anyone know what I'm doing wrong?

using HDRP btw

[hallow stag]

Guys, is there a way to use unity's exported lightmap to a dynamic gameobject ?

[tired edge]

I am trying to figure out why every time I bake the lighting the shadow from the window looks like this :

[tired edge]

nvm found it^^

[narrow nova]

Hi, after baking lights I have this issue with a shadow. The shadow drops to the bridge and unexpectedly also to the ground below. Do someone have some solution?

[safe fox]

Why even bother asking at this point, noone is gonna answer anyways regarding lighting

I mean every other channel there are answers to questions, here the questions just stay unanswered lmao

[summer aspen]

@safe fox So what exactly are you trying to say?
If there are people who know something about the problem and have time to do it they will answer.
There's no need to spam the channel with nonsense.

[quartz yacht]

@safe fox Seems like a pretty shitty thing to say to the face of all the people who actually do answer these questions. #archived-lighting is the only place so far where I've seen people receive personalized video responses addressing their questions. Definitely not interested in hearing your take on the quality or quantity of help in these channels.

[white parrot]

Is there a way of preventing light bleed through 2d walls? Does Double render faces stop this?

[summer aspen]

Turning on double sided shadows fixes some issues with light bleeding in

[white parrot]

maybe that's what I have been doing wrong, I was doing double sided on material not object

I will give that another bake 🙂

[safe fox]

Seems like only 1 out of 100 actually gets answered here, while in the other channels nearly every question gets an answer

Was just an observation that an help channel were (nearly) noone seems to help is kinda useless

Or like 1 in 100 chance to get an answer, both might be a bad thing to say but thats what im seeing here

[mellow sierra]

What are you angry at exactly? That the majority of people here are beginners asking for help, or that the far more advanced people are less active?

[safe fox]

Not angry at all

[mellow sierra]

There are other spaces for asking questions. Try unity answers, Reddit, etc.

[safe fox]

Its just weird that the other channels get help on nearly every question and here its like asking a wall

(where the wall randomly sometimes answers)

[mellow sierra]

It's not weird. Lighting is an advanced topic.

Obviously something like #💻┃code-beginner is going to get alot of help, even beginners can help beginnners.

[safe fox]

True dat, why am i even observing / talking about it

Like nothing is gonna change

[mellow sierra]

This conversation can literally go nowhere. There's nothing you can do about forcing people to help you. Just try other places, and try solving your own issues by researching instead of waiting for someone to guide you through it.

[safe fox]

Guys, some gameobjects in my scene is really far away (like at 0, 10000,0). The baked lightmap looks like this. How do i fix it ?

[mellow sierra]

By not having things that far away. Things just start breaking down the further away from the world origin you get.

[fast pendant]

Anyone happen to know what could be smothering my lights in HDRP? All my point lights show rather bright in prefab edit mode but when placed in a scene they are dramatically darker. Been clicking through all the HDRP and post processing settings to no avail...

It's something over distance, as it's not linear--I have to crank up the brightness to cover the area, but it makes things near the source blown-out-bright... but fog is off

[lost hatch]

Hey, does anyone know why my lighting randomly changed to this? I was using the project an hour ago with no issues but when I opened it after coming back everything looks like this? Cheers!

[weary escarp]

[lusty sierra]

Does anyone have any resources on making lighting look like the standard pipeline when updating project to urp? I updated because I want to use the shadergraph but it made the lighting look like shit

[safe fox]

Thats a scuffed "solution", what if you have a big map lol

Lol its not even a solution imo

[mellow sierra]

It's not a solution, it's a fact of game engines.

And how floating points work (or breakdown) and large scales.

[safe fox]

Great Question, it might be a bend lightcurve since youre missing a quantumcore with embedded lightmass.

Fr tho how should we know, send screenshots of your scene, light setup und editor lmao

[safe fox]

So what youre saying to him or people with big maps is: Go to Unreal, Unity cant do it.

Interesting take, maybe idk make that a priority, maybe even a high one to fix ?
Battle Royal or Big Maps are coming and gonna be Mainstream.
This is bad, really bad to just say: "yeah no"

Especially if its not floating points or large scales but the engine

Since Unreal can handle such big maps no problem

[mellow sierra]

Don't put words in my mouth. Games like KSP are built in Unity and have ways of dealing with it.

I personally don't know what the best solution is.

[safe fox]

Well if you said not having things at that distance kinda implys there is no solution

If there is no solution well the solution is using another engine

Not really good for unity innit

@hallow stag please file a bug report with unity, they need to fix this.

[mellow sierra]

Honestly, I'm watching TV and eating dinner I'm not really into this conversation. Lol. Use another engine if it solves the issue sure.

[weary escarp]

Heres the scene

[quartz yacht]

@safe fox Unreal, as basically all game engines and frameworks have the same issue, in fact any system using floats has the same issue. Unreal does have a way to built-in way to deal with it, but you need to support it for the stuff you build and Unreal straight up doesn't support it for multiplayer. Unity has the same world origin shifting support on the roadmap for rendering, and probably odds are it will get more support in the future.

The issue is that there isn't a clean way to solve it for all cases automatically, since it's an inherent issue to precision for types that are commonly used.

[timber lichen]

i keep getting this lighting problem after switching scenes when i turn off the auto generate and if i set it on i always have it

[leaden glen]

What possible settings could I be missing that causes my object to still have shadows? I've turned off both cast and receive under the Skinned Mesh Renderer, material shouldn't have anything causing it....at a loss here

Doi, nevermind. Shader type to Unlit/Transparent Cutout works nicely

[weak agate]

For some reason the lighting on the head is coming from the proper angle and the lighting on the body is reversed

[mellow sierra]

Check if your normals are flipped

[weak agate]

I can't check for just the body, I can only find how to check normals for the entire Avatar

[mellow sierra]

Open the model in Blender and check there. You'll have to flip the faces anyway if they are inverted.

[weak agate]

fixed ! thank you dearly

[weak agate]

so unfortunately it didn't quite fix, flipping normals gives me the options of the body having its shading reversed or all the faces being flipped so you can see inside

only on the body of course, for whatever reason the head is fine

[gritty bloom]

im new here. what is wrong with the light??

[worldly nova]

What causes these seems?

Hello im working on some hallways for my game

and i have made sure the vertexes line up perfectly

but i get these weird seem lines

iv tried importing normals vs calculating normals

fixed this by deleting lights outside the test hallway

[rapid topaz]

Hi! I hope someone has seen this issue before, and can help us. We have an HDRP scene (Using the default HDRP project) on this scene we have a little airplane cabin section, with 4 windows total. The scene is lit by a directional light. Everything is baked. After baking the scene, the lights are smooth, GI is well calculated, but the inside of our meshes have weird shadow spots on them.

What we tried so far:

• Disable denoise and filter completely to see the GI -> It's not a GI issue, the white dots for the bounces are uniform across the surface.
• Let Unity Generate lightmap uvs -> Looks the same
• Flip/Recalculate mesh normals -> Looks the same
• Directional/Non-Directional bake -> Looks the same
• Generate different UV layouts -> Looks the same
• Detach problematic surface from model, UV separately -> Looks the same
• Increase indirect samples (10k from 1k) -> Looks the same
• Increase min/max bounces -> Looks the same
• Use different materials for baking - > Looks the same

This is the actual shadowing that looks weird

This is the actual lightmap. It's clear that it's built into the lightmap itself

We are using the Ultra quality LightingSettings from the HDRP project

This is the UV layout of the problematic part. There are no overlaps whatsoever.

Brand new to unity, no idea what could be causing this issue or how to solve it :/

Increasing the lightmap resolution, just makes the errors nicer 😄

[mystic dew]

can you try to bake only this separate part with problem in separate scene?
What if other objects (maybe SHADOWS ONLY mesh) cause this problems?
