@sheila5 I’m on a Mac right now, that is why it says OpenCL, in my home laptop it says CUDA as well. I think that has to do with the Video Card maker, in CUDA case is NVidia. is it the CPU or GPU that is greyed out for you?
The “Experimental” setting were for the Toyota scenes, this scene is a different one. That settings have been the same ever since I uploaded it. The render time is probably because you were rendering with your GPU and now you are doing so with your CPU. The problem is why can’t you now not render with your video card?
Try updating your card drivers. That’s the only thing I can think of right now.
