Hello in my project I am trying to render a transparent mini map with viewport (like the ViewHelper ) in conjunction with the TSL pass and PostProcessing system (I need it for several different effects in my project).
I am running into rendering differences between the post-processing.render and renderer.render, where the post processing has a white background for some reason.
My question is what is the correct way to get a setup to work like this?
How do I configure renderer.autoClear for the post processing setup?
