Is there a way to prevent cycles from rendering useless empty space? I have a single object over a transparent background. I’m doing a panoramic shot in 4K. Cycles spends minutes and minutes rendering absolutely nothing. Just as a test, I even had cycles render a completely empty scene - it took forever. I’m trying to send the scene to a renderfarm. They quoted $1000. The idea of paying $1000 for all this empty scenery is just insane. Is there any way to prevent cycles from rendering useless empty space?
