Tried both and went with BodyPaint R2 as Deep Paint kept crashing on me. Both have a relax function that is very similar. BodyPaint manual is a ref guide with little tutorials and vid tuts on the CD, they cover the basics but leave a lot to learn on your own. No online tuts, little support but the program is stable as a rock and works like photoshop very well. All the materials get assigned seperately like layers, you can turn um on and off and its pretty easy to use the work flow once ya overcome some of the learning curve. I have not used the UVin much in BodyPaint but the features seem good and robust and I've head as good as DeepUV but I could really give you a comparison. All things being what they are if I was to purchase again I would go with DeepPaint. There are more poser users, more support and it's industry used. Too expensive now to switch. Currently I use UVMapper 3 free download and Photoshop 7 and rarly use BodyPaint due to the frustrations and learning curve. My 2 cents. Les of Sixus1 uses DeepPaint and is quite knowlegeable as wel as the folks over at RuntimeDNA and they are quite helpful with questions. If you need help with DeepPaint check out both forums ans ask some questions.
