I've had plenty of issues with D4, mainly the Ui interface. I'm VERY particular and I'm use to how I have it set up on D3. There are complaints galor on the daz forum over at daz. I deleted D4 because I was not comfortable with using the new layout. As said over at daz, like the saying goes, "if its not broke, don't fix it"' well...they broke it alright. There appears to be an issue with the mac version as well. Until there is a 64bit version, I'm remaining loyal to D3. it works for me and I know it. Also, the render in D4 is no better than d3. Its the same. Also btw..to answer the question above, YES, the auto tool will be part of D4 Advance and Pro. IF, they get their act together.
