AlexMerzlikin / UniversalRenderPipelineTemplateWithDotsInstancing.shader
Last active November 7, 2024 09:33
Template unlit URP shader that supports DOTS instancing to use as a guide to create shaders for BatchRendererGroup since BRG only works with DOTS instancing compatible shaders. Unfortunately, the official docs about it haven't helped me that much, and I thought others might face the same issues.
Shader "Universal Render Pipeline/Custom/UnlitWithDotsInstancing"
{
Properties
{
_BaseMap ("Base Texture", 2D) = "white" {}
_BaseColor ("Base Colour", Color) = (1, 1, 1, 1)
}
