[LWRP]Any macro in shaderlab tell which pipeline is using?

Hi,I have to make a adaptive fix for our old build-in pipeline plugin to support LWRP.
I create a new SubShader with Tags "RenderPipeline = "LightweightPipeline",so that in LWRP project shaderlab with use the first subshader and build-in pipeline use the second:

Code (CSharp):

1. Shader ""{
2.     SubShader {
3.        Tags{"RenderPipeline" = "LightweightPipeline" "Queue" = "Transparent"}
4.         //...
5.     }
6.  
7.     SubShader{
8.        Tags{"Queue" = "Transparent"}
9.         //...
10.     }
11. }

And obvisouly the two subshader has lot of same logic but little different code,I want to strip them out,and use a macro to define the different code,any build-in macro support this? such as:

Code (CSharp):

1. #if LWRP
2.   //...
3. #else
4.   //...
5. #endif

 

Couldn't unity editor aware about it and set some project wide define for us?

 

Hi, I stumbled on this thread as I wanted to keep my shader somewhat compatible between using either UnityCG.cginc or Core.hlsl (the latter only usable when also using HLSLPROGRAM macro instead of CGPROGRAM).

The following seems to work:

Code (CSharp):

1. #ifdef UNITY_CG_INCLUDED
2.     o.vertex = UnityObjectToClipPos(v.vertex); // old
3. #else
4.     o.vertex = TransformObjectToHClip(v.vertex); // URP
5. #endif

 

Would be nice if a define existed for each of the render pipelines. Seems simple enough..?

 

Is there any documentation on this anywhere? This post by itself isn't enough to figure out how to determine what these defines are.

 

It would be great! Would also be great if they didn't do it halfway, and added nodes to shadergraph to check these defines existence as well for conditional compilation!
