I started out with RD, then I got a into ID and I found that much that I had learned about 3-D in RD applied very well to ID, even though they ware radically deferent UI. I also found that ID was very intuitive in as much that you could get along just fine without picking up the manual. I like the way you could texture in layers in ID which I miss on Carrara know. I don't se Eovia bringing back ID. I just wish, like you do that more of it got put on the mix when Carrara was concocted.
