HDRP custom shader with indirect instance support
This is my experience writing a custom HDRP 5.6.1 in Unity3d 2019.1.0b7
Indirect instance in HDRP is another history. Because in HDRP every objects depend of the relative camera position.
The shader that I share with you needs a custom ".cginc" In this file I set the position, rotate and scale foreach instance.
In the custom shader HDRP I was add pragma looks like this. #pragma instancing_options procedural:setup for call the function.
The script Scatter.cs send the buffer at shader between another things shapes dispertion. For now support circle area and square area.
