It's buggy but I dont think 1.05.30 is a better product. Just the ambient occlusion, IES files, and transparent PNGs are enough to convince me to deal with the bugs. As for the debug menu, you have to go to Plugins - VRay - Help - Debugging. There are a few options in there. Beware that this will reset all materials in your file to defaults.

Yea - 1.05.30 is more stable - but the features of 1.49.01 is so good that I can't ignore it. Fortunately a new beta should start soon. 😄
