Hi, I have a problem with my compute shaders. They compile fine and the program runs at optimal FPS but they appear to output nothing. I have tried to debug it for a couple of days but have not found the cause yet.

The first one is supposed to just increase a value every frame (to simulate snow piling up).

The second shader should write deformations caused by objects at the given world position into a texture and then determine the minimum between all values wrote to the cell. It also writes the y-value of the world position to the least significant bits of the 32-bit uint uav for later processing.

This is the call in the methods:

Thanks in advance,

Tobi

I assume you've run with the Debug Layer enabled to check it's clean and error free?

I also assume that the comment "//called by dispatch(1,1024,1)" is wrong?

yeah I am running with Debug Layer enabled and there are no errors or warnings.

The comment is not up to date that is true.

Have you tried using RenderDoc to debug what's going on?

I am currently debugging the frames. The resources are all bound correctly but the data is not changing inside the UAV.
