Entities Graphics Skinned Mesh Renderer Optimization

This repository contains optimizations described in https://blog.rukhanka.com/optimizing-smr.

How to use

1. Clone this repository into Packages folder of your project.

2. Remove original Entities.Graphics entry from manifest.json

3. Make changes to the animation-aware shader graph:

   • Create "Custom Function" shader graph node.
   • Configure the node with the following properties:

   

   • Connect vertex data input ports with object space vertex position/normal/tangent properties.
   • Provide vertexID node with appropriate data.
   • Connect output ports with corresponding inputs of the master vertex node.
   • Create "_ComputeMeshIndex" property with "HybridPerInstance" declaration:

   

   The final shader should look like this:
