HDRP Decal Projector missing Affect Transparency checkbox for Decal Graph shader

Hi!

I'm currently using Unity 2019.3.0f6 with HDRP 7.2.1.

My problem is, if I create a shader using "Create/Shader/HDRP/Decal Graph" I don't have the option to make it affect transparent objects. If I use the shader "HDRP/Decal" the checkbox is there. Am I missing any step?

Custom Decal Shader


Using HDRP/Decal shader





Thanks!

 

Update: Found this in the source code for the DecalProjector and DecalSystem.

This is found on the DecalProjecotrEditor.cs

Code (CSharp):

1.  bool showAffectTransparency => ((target as DecalProjector).material != null) && DecalSystem.IsHDRenderPipelineDecal((target as DecalProjector).material.shader);

And this on DecalSystem:

Code (CSharp):

1.  static public bool IsHDRenderPipelineDecal(Shader shader)
2.         {
3.             // Warning: accessing Shader.name generate 48B of garbage at each frame, we want to avoid that in the future
4.             return shader.name == "HDRP/Decal";
5.         }

Help?

 

Hi, Thanks for the information!

So, for now, is there a way to make a custom projector that affets transparent objects?

 

hi @SebLagarde is there any update on that?

 

Hi @SebLagarde,
Trying to do some custom decal shader graph shaders that apply to transparent surfaces but ran into this issue.

Have noticed that switching material to HDRP/Decal enabling "Affect Transprent", then switching back to custom shader works for a bit, but after reloading Unity it seems to default off again.

Is there something under the hood now that allows for this but it simply forced off by Unity code?
Is it possible custom shader graph shaders will have access to "Affects Transparent" in future versions?

Thanks

 

@SebLagarde Any updates?

 

shucks.

 

update ?

 

@SebLagarde any updates? )
