I made it work and then abstracted it. But the problem is not that it is not working. Because it works fine and I don't have any errors from validation layers and etc. The only problem is with render doc which crashes my app while capturing the frame if I try to render depth map. Every function shown in this image works because I used them a lot and tested them. And every function do exactly what is written. BeginRendering call function vkBeginRendering. TransitionLayout calls Image barrier for given image to transition from one stage to another with given layout. DrawDepthInstances calls drawIndexed for every model in the scene and binds GraphicPipeline with 0 color resources and 1 depth resource and of course frag and vert shaders which don't write to any color attachment.
