For some reason, all of a sudden, all my renders produce a black screen. OpenGL produces images, but Cycles doesn’t. I can’t think of anything I’ve done that would cause this. The render settings are correct, the lighting in the scene is correct, I’ve been through everything I can think of including restart and reset. I was playing about with gravity on a couple of mesh objects, but they are now deleted. I was also playing with a repeating path, but those objects are also deleted.
Has anyone come across this before, have any ideas?
