Well, I learned both apps from texts downloaded from the Net, incl. program manuals. There is no book in PL for C4D and only one book about game making in Blender-I bought it and found of little use. Anyway, the interface is really strange for me and I find C4D much more easy. Another problem is that Blender still produces some problems on my machine, incl. poor renders and extremely slow interface (this is a problem with my graphics card, I was adviced to solve it by decreasing the screen color depth, but what is the use of a graphics app that requires low color depth?!). I tried 2.36 rc of Blender that has some graphics card bug fixes, but still I have to use 256. I think C4D just fits me better... I always liked cinema more than the kitchen:P
