[Released] Lux URP Essentials

Apparently this happens when converting a material with a lit shader to versatile blend. Apparently some of the hidden/unused inputs from the lit shader are affecting the behaviour.
When copying the material from the demo scene and just changing textures etc. it works fine.

 

ah, i see. you can go to bebug view (3 dots in the upper right corner of the inspector window) and look for "disabled shader passes".

 

Hi, is it possible to add a cutout mask for the skin shader? I'll need this feature to hide skin parts when dessing up my character.

 

i have no idea why this is needed. of course it is possible, but you would have to do it your own: adding cutout will slow down the shader. so i would recommend to dive into your models and find out what is going wrong here.

 

I'll try to work on my models then. And is it possible to have a hair shader with the cutout pass and the blend pass together inside one shader? Unity warns that using two materials on one mesh is more performance heavy than an additional pass.

 

it used to be not. it is now. but you can simply ignore the warning.

 

Hello, I was hoping to use the unlit decal shaders for a top down rpg character selection, but they are projected on everything including the characters. I have read the manual and tried a lot of stencil settings combinations but I just can't make it work. Honestly I still don't understand the stencil settings in the shader after reading the manual.

Can someone please explain how to make a decal visible only on only the terrain or/and ground with a certain layer?

 

layers are a cpu not gpu construct. but instead of using the stencil buffer you can try to use the render queue to limit the decal to anything drawn before it. examples are in the demo scene.

 

I'm on Unity 2020.3.11f1/URP 10.5.0 (Upgrade from SRP) and just realized that more than half of the Lux shaders are in the "failed to compile" list of shaders. When I completely remove the asset and reimport I get these errors:

I'm not sure what to do. I already removed URP and reimported it, then imported Lux Essentials but the error and failed compilations are always the same. Any idea how to solve this?

 

you have to install the urp 10.3.2. support package (you will find it in the lux urp essentials folder).

 

Thanks Lars, problem solved!

 

Hi lars, do you plan to make an eye shader for Lux URP? There doesn't seem to be a simple and decent eye shader for URP right now on the store.

 

i have no plan right now, but may add it to the list.

 

Looking forward to it

 

@larsbertram1 Personally, you prefer Unity 2021 Alpha / Beta because you're working so close along with Unity's development of URP, correct?

So if we want to use the fastest / most modern UPR / URP essentials features, we should use Unity 2021, correct?

Or do you think URP is already quite completed, and people should use Unity 2020 LTS + Lux URP Essentials + URP 10?

 

unity 2021.2 and urp 12 will bring a lot of changes: deferred, enlighten, forward+, light cookies, ...
so choose urp based upon your needs, target platform and time frame.

 

Using URP 12 (unity 2021.2) the only "big" error I've found was in Lit Extended shader, when calling for LiteweightFragmentPBR function in the shader, the function now is renamed as UniversalFragmentPBR.
The rest seems ok.

 

oh, lux urp essentials currently do not support urp 12. some things work, some do not.
and upr 12 is evolving so fast that it does not make much sense to publish a package – even as preview.

 

Oh yes, I was aware of that. URP12 feels like a tremendous leap, but in the right direction.
When URP12 come out of beta you will support it?

 

i will do my best.

 

I'm using 2021.1.11f1, URP 11, I've installed the URP 11 package inside the Lux folder, and I still only get pink textures. Any guidance would be awesome!

 

Fixed it! In my project settings, I noticed the Renderer asset was missing and none were available. Turns out I needed to actually create the URP asset manually by going to ASSETS ---> CREATE ---> RENDERER ---> URP ---> Pipeline asset

Worked like magic!

 

@larsbertram1
hi,
how can i implement vertexmotion Features to skin shader?

thanks.

 

you will have to edit the shader and add the code to the vertex shaders (forward, shadow, depth and depth normal passes).

 

Hello, I am trying to get the decals from this package to show up on transparent materials. Is this possible, and if so, could there be a step I am missing?

 

only if the transparent materials write to depth which they usually do not.

if you make transparents write to depth you have to make sure that the decals are rendered afterwards.

 

So I use Lux URP/Glass with zwrite on and write to Transparent 3000

I then use Lux URP?Projection/Decal Unlit with render queue 4000 (Transparent+1000)

Would that be enough in theory?

 

transparent + 1 would be enough.
transparent + 1000 might already be ui or something.

 

Except that it is not working

 

have you checked the water in the demo scene?

 

Hi @larsbertram1.
I'm Atsuo. Can't really change the name on this forum. Sorry for inconvinience.

Thanks for making URP shaders. They helped me a lot.
But I found an issue about alpha cutoff in hair shader. Cutoff results are different between Win and Mac.

On Windows, Alpha Cutoff 0 looks fine. Alpha still works.


On Mac, Alpha Cutoff 0 looks not working. Alpha is ignored.


Unity 2020.3.11f1

Win:
Windows 10
AMD Ryzen 5950X
128GB RAM
Geforce RTX 3080 Ti 12GB

Mac:
MacBook Pro (16-inch, 2019)
2.3GHz 8 core intel core i9
32GB RAM
AMD Radeon Pro 5500M 8GB

Could you check this issue please?

 

hi atsuo,

cutoff = 0 should show the entire quad here.

this is how it should look like.

anyway: it should work on both- unless you have messed up something with the materials.

 

Thanks for your reply, @larsbertram1.

I'll look into a material that I use for hair.

Atsuo

 

hi there @larsbertram1 I bought the extension and I've been trying a bunch of stuff to get decals to work on top of "Lux URP/Glass" but I can't seem to make it work, I followed every step of the documentation, I have depth texture enabled, installed URP 10.3 package and it still doesnt work...

Do I need to mess with the render queue or the stencil buffer, If I just assign a default glass material ? otherwise could you provide a simple project with a decal projecting onto a glass material?

thanks!

 

oh, my fault: even if the glass material writes to the depth buffer - it will never land in the camera depth texture which only contains opaque geometry.
i made a quick test in the "decal demo" scene and somehow managed to make the decal show up on top of he glass.
in order to make it work:

• you have to assign a 2nd material to the glass object only writing to depth using the opaque pass. use the material "M Lux URP Depth Only" e.g.
  
• make sure the decal you want to project on top of the glass renders after the glass. so set the render queue of the decal projector to 3001. glass uses 3000 by default.

below you can see the result as well as the 2 materials being assigned to the sphere.
the "depth only" material may occlude other opaque renderers, so you would have to tweak its render queue as well and set it to "alphatest" + something to make grass e.g. being properly rendered which uses "alphatest".

 

@larsbertram1 sorry to be "that" guy, but here is my problem:
I've being using LUX URP on Unity 2020, 2021.1 and 2021.2. When the scene contains a Volumetric FXs (like Volumetric Box material) it hangs up entirely. However, it's matter of luck: I will guess around the 5% of the time.
It hangs up the editor (nothing responds, a check on the Task Managers shows the Unity.exe running the game is "nonresponding") and when building the player, also happens. Only solution then is to close it completely.

My scene is as follows: I've a "Fog" based on the Volumetric Box FX material of your own examples, on a GameObject. It's shown only on certain scenarios, for short periods of times (i.e.: when changing the camera view). So, the GameObject is SetActive(false) most of the time. When the games is in the specific scenarios when the fog it's shown, sometimes -just sometimes- everything hangs up.
It occurs when the Fog (Volumetric Box) it's on screen. NEVER when it's disabled or offscreen.

Did you have any guess?? Thanks in advance.

 

sorry, no. it works just fine for me. even on my 8 years old mac book pro laptop.

 

@larsbertram1
hi dear,

can you guide me to how to implement this Mesh Deformation Compute Shader in to the LUX skin shader?

thanks a lot.

 

sorry, i can't. you just have to make the shader oick up the data generated by the compute shader. this is not related to the skin shader at all.
but why don't you simply use a skinned mesh? it also compute. and you have a well defined pipeline here.

 

I can confirm, LUX URP it's not the problem. Thanks anyway.

 

Hi, if I want to add alpha clipping feature to the skin shader, where should I look into?

 

you have to go through all passes (depth, shadows, forward,...), sample some texture and add a clip command.
you also have to decalre a threshold property in the shader properties and the cbuffer.

 

I know how to add a sample texture and declaring a threshold in properties.
But don't really know how to apply them in each pass. Where should I insert my code in the skin shader's passes and how do I add a clip command?
I'm very new to shaders...sorry for any inconvenience

 

depending on which texture stores opacity you first sample this texture like:
half4 albedoAlpha = SAMPLE_TEXTURE2D(_Texture, texture_sampler, uv);
clip(albedoAlpha.a - _YourThreshold);
you can also look into using one of the predefined macros.
or use the shader graph version of the skin shader.

 

ok, thanks, I'll try this.
BTW, where is the shader graph version of the skin shader? I'd like to try add the alpha clipping in shader graph, too.

 

if you open the custom shader graphs demo there should be 2 heads. one of them uses it.

 

hi there,

i just want to let you know that right now i am uploading the preview package for URP 12 and Unity 2021.2.0b4.
i am not sure if this is a wise decision as things most likely will break with the next beta. anyway.
the preview package only contains some cherry picked shaders updated as it is just so much work to do...
you will find details here: https://docs.google.com/document/d/...YUW9OsGL0niCL0MlY/edit#heading=h.6zvjnfuiskj1

the update should be available within the next 2 days i think.

funny thing: a blog post from April 16, 2019 where Unity claims that LWRP is now out of preview and production-ready.
since then i have tweaked and rewritten the shaders 3 or 4 times? well, production ready in unity's sense means: shader graph shaders will be updated properly... time to change my profile image and turn it pink.

 

Yup when you change it I will follow too xD

 

for those who want to try URP 12: the preview package is now available.
