There is a runtime render debugger and no one talks about it


The entire render debugger is accessible in development builds. I’ve never heard anyone talk about this. It’s amazing you can toggle lights, post processing and do all kinds of stuff.

This might be a good time to also mention RenderDoc, which is a fantastic bit of software for capturing the exact state and draw calls. Works both in editor and build, and is essentially the Frame Debugger on steroids.
