I really like where Corona is going guys, well impressed with RC2 overall, it's a major step change from the earlier Alphas.
Having said that I'm still getting regular crashe, one of the worst offenders seems to be denoising but it seems more solid than before overall.
I'm also having a problem where I start a render but can't stop it. Closing the picture viewer doesn't give the usual popup to stop the render and the Corona VFB Stop button is greyed out. The only way I've found to stop the render is to quit C4D. This tends to occur after doing a few test renders on a scene while getting the look right.
