Question Alpha to coverage ?

Hello,

Is it possible to implement alpha to coverage in an unlit shader with URP ?
I saw that we needed to add this :
AlphaToMask On

But I'm not sure how to do it with the shader graph.

Does someone know if that's possible ?

 

I don't think it is in ShaderGraph yet but you can just manually add that into your shader and it should work.

 

Hello Deverolirc,

Yes this is what I thought.
I created some shader with code just to implement this.
It still would have been nice to be able to use it as a booleen in shader graph.
I now have several shader variant thant I need to update every time I update the base shader.

Maybe I should just create the shaders without shader graph :/

 

Amplify shader editor has the option as a simple checkbox. Shadergraph still doesn't.

 

Fyi, this was added to URP shaders and Shadergraph in Unity 2022. It's automatically implemented in any alpha cutout shader.
