DIRECTX12 - Can't write DepthBuffer — result is completely white
I am new to DX12 and I am currently trying to get the depthbufferdepth buffer to work. I have done pretty much everything identical to blogpostsblog posts I've seen online. I can also see that the depthbuffer-texturedepthbuffer-texture is there in renderdocRenderDoc, itsit's just completely white (see here):
enter image description hereWhite image in RenderDoc
Also, the depth target is in D3D12_RESOURCE_STATE_DEPTH_WRITED3D12_RESOURCE_STATE_DEPTH_WRITE state. I've set all the settings in my pipeline so it supports depthtestingdepth testing, matched the formats and everything.

I don't understand why itsit's not working -— help would be verymuchvery much appreciated. I dontdon't want to spam this complete thread with code (since itsit's quite a lot of boilerplate) so if you want to look at the complete code you can check it out here: https://github.com/eliasfuericht/artisDX/blob/main/src/Application.cpp
