Using Unity 2022.3.40f1 and URP.
I'm trying to implement occlusion culling with the depth buffer in a compute shader.
I don't know what's wrong here but my code only works fine with the scene camera ...

How do I achieve the ping-ponging technique in HLSL compute shaders?
I am doing a fluid simulation, and implementing such simulation with the CPU is very slow, especially when the simulation grid size gets bigger or is a 3d grid. So I used shaders to get the ...

Load raw texture data / Getting data from compute shader
Overview
I have been working on a compute shader for awhile now. Initially it would take in 1 camera feed of 320x256 pixels. This all works great.
Now I want to be able to handle multiple cameras, ...

Compute Buffer of bytes to RWTexture2D float4 in Compute Shader
I'm struggling with a Compute Shader whose purpose is to take a byte array of rgba values and write them to a render texture. I'm passing in ints (as I don't believe I can use byte itself) to the ...

Incorrect Frustum Culling behavior
I've written a C# script and a Compute Shader that should cull the instances that are not visible by the camera. The instances are getting culled but with some weird behavior - sometimes not getting ...

In a tree structure in Unity / C#, how do you sum calculated values from root to leaves using ComputeShaders?
This wouldn't be too hard if this wasn't mixing several worlds : the world of algorithmics, the world of C# and the world of compute shaders (in Unity).
EDIT: This is somewhat related. My scenario is ...
