I have installed Corona A5 yesterday, I found this one great, simple and intuitive.. Looks very promising.. But only one concerns.... Maybe I've missed something... Maybe I so used with VRay. But usually with most render engine, they have progress bar that can tell when it will end. But with Corona... Its different and I am not aware or know when it'd end. My still running at 245th passes and continuing for 20 minutes and I only have a simple torus knot, simple red glossy material and a two rectangle light at intensity of 10. The result look so clean, no noisy. I only wonder does it ever stop?
