I am currently working on (of course) a large scene and have some materials with emission on and indirect lighting settings. Rendering one signle frame of the animation on blender took 44 minutes and about 40 of that was “occlusion preprocessing”. The animation will be about 300-400 frames long and has a lot of emission objects in.
Is there any way I can use this strange bake panel in render settings to speed things up? I tried obviously selecting “emission” and bake, and it drew a white patch and then quit with the message “feedback loop detected”. Does this just bake one single frame? All of the lights in the scene are static except for maybe a sun light which shines through moving clouds to make nice shadows on the landscape, although I’d make that a static object if it meant I could cut those 40 minutes down a fair chunk!
