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.

The SV_InstanceID issue has been fixed in Unity6 and you no longer need to patch it.

### 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. NOTE: This has been fixed in Unity6 and you no longer need to patch this.

- 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"
