Hey guys, here are some issues I found when attempting to use the rendering:
Firstly, I lose my background every time I close the render+ the menus:
Ambient occlusion/contact shadows do not respect the surface material. So in the example below the floor is black rubber however the contact shadow is grey-white, which would be correct if the surface was a pure white… as is it looks like the car is emitting light, not the result that would be wanted.
The ground shadow function appears to be set at 1 specific location in the scene. I didn’t know this and built above the ground level, when I tried to move my car I broke it permanently.
