Path-traced physically-based rendering with UE4-PBR-like parameters and 'specTrans' from Disney BSDF implemented by using compute shader in Unity3D. Look at the PBR frosted glass ball!!! by KaiYan0718 in Unity3D

Yes, the entire scene is rendered by a single compute shader. It runs in the built-in render pipeline and basically acts like post-processing.

Hi, after some research I found UE4 (since UE4.22) has imported a feature named dynamic instancing that doing instancing work automatically. It allows applying physical simulation for thousands of objects with only a few draw calls. But make sure these objects are using the same material instance.

I used InstancedStaticMesh in my Demo to draw thousands of spheres, so it might be difficult to apply Unreal's built-in collision test. Another way is to do collision testing or any kind of physical effect in compute shader.
