Unity Shadergraph Patcher

Patcher utility for Unity Shadergraph shaders.
Adds features to Shadergraph shaders that are currently not available in Shadergraph.
Tested with Shadergraph 14.0.11 and URP 14.0.11 . HDRP has not been tested.

Features

• Use SV_InstanceID instead of unity_InstanceID when using the InstanceID-node. This breaks instancing support for the shader, but in return allows using the shader with IndexedIndirect render functions. i.e. Graphics.RenderPrimitivesIndexedIndirect
• Add "nointerpolation" attribute to CustomInterpolators / Vertexshader output
• Support for uint, int, min16uint and min16int vertex input attributes. i.e. "float4 uv2 : TEXCOORD2;" becomes "min16uint4 uv2 : TEXCOORD2;". NOTE: This will ONLY patch vertex INPUT! All other nodes/code will not be affected.

Patching

When patching a shader, the original shader(graph) will not be touched and a new shader will be created instead.
The new shader will have the suffix "_Patched".
i.e. Opaque.shadergraph will become Opaque_Patched.shadergraph
The name of the new shader will also be changed.
i.e. "Shader Graphs/Opaque" will become "Shader Graphs/Opaque_Patched"

If patching both SV_InstanceID and nointerpolation, "InstanceID" in the screenshot above will contain SV_InstanceID instead of unity_InstanceID and "NoInterpolationData" will get the "nointerpolation" attribute.

How To

Copy the "Editor" folder to your Unity project. The patcher will then be available under "Tools/Shader Graph Patcher".
Drag and drop a shadergraph or shader to the window and select the features you want to patch.
Then press "Patch"
