Hello. I was having this problem with Rhino 6 Beta and am still having it with the new release. Raytrace works for a while and then begins behaving like regular Render, not even ticking off iterations. Sometimes restarting Rhino helps, sometimes it doesn’t. I thought it might be the complexity of my model but tried it on a very vanilla cone, in the attached file, and get the same result. Are there some settings I’ve neglected or something else I’ve overlooked? Thanks.
