Rendering only SceneDepth in SceneCapture

Or maybe there is a way to optimize SceneCapture so that it does not render anything other than depth?

Optimize Scene Capture depth rendering

If scene capture is in SCS_SceneDepth mode, then I am forcing it for scene captures only in code and I am also forcing full prepass, so no objects are ignored. However, I am not sure how good is this for different platforms, that’s why I was a bit sceptic when It comes to PR. I will do some improvements, tweaking and then do the PR.

Not without modification to the engine I believe. This thread seems to have a pull request where that modification was implemented.
