I can access the same with duplicating the cameras AND the rendertextures, but that seems like a lot of overkill of just getting the depth buffer.
I don't need a very precise depth buffer, so it can easily be put in the alpha channel.

\$\begingroup\$ It sounds like you answered your own question: "put depth in the alpha channel". What happens when you try this? \$\endgroup\$– DMGregory ♦Commented Jun 7, 2023 at 23:05

\$\begingroup\$ Hi @DMGregory, I only see one "depth" setting with ColorFormat on the RenderTexture - and that is called Auto Depth and puts it in the color channels. So then it doesn't write any colors anymore. \$\endgroup\$– Dirk BoerCommented Jun 8, 2023 at 12:03

\$\begingroup\$ So write a shader that puts depth where you want it while rendering the colour components, or use a post process to copy the depth texture into the alpha channel? What step do you need help with? \$\endgroup\$– DMGregory ♦Commented Jun 8, 2023 at 12:23

\$\begingroup\$ if I need both the depth and the color channels then I need to have two cameras (camera can only write to one rendertexture) and two render passes. I will take a look at postprocesses (but I am still using the legacy pipeline) \$\endgroup\$– Dirk BoerCommented Jun 8, 2023 at 12:56

2\$\begingroup\$ No, Unity also writes a specially-named depth texture that you can read from while the camera is rendering (and I think in OnRenderImage just after it's finished). Here's an older presentation about it that describes how to use it in the legacy pipeline. \$\endgroup\$– DMGregory ♦Commented Jun 8, 2023 at 13:04
