Bodypaint2 has some good advantages, although it is not really cheap. But neither is Photoshop. 1/You get an UV editor with it, and imo one of the best and most complete there is. 2/ The start up wizard takes care that you're painting after less than a minute after first time start up. 3/ It comes with a set of video tuts that you don't have to pay extra for 3/ You can paint on multiple channels at the same time, or separately. Channels like color, bump, displacement, alpha, transparancy, reflection, environment etc. And you see your result immediately. 4/ You have all your Photoshop filters at your disposal as it links to the PS folder on your hdd (or any other 2D editor, although I must say that I did not try this out.) 5/ You get much of the functionality of Cinema8 in it. 6/ Maxon really listens to their customers and often offers free updates that other companies would consider to be an upgrade that has to be paid for. Only this: there are some plugins to import Poser files directly, and there will be one from CL coming before the end of the year (see interview here at R.), but if you want to simply import the mesh as obj file, multiply it quite a bit in BP's import settings (some 200). If not, it will be too small.

I have tried prudent planning long enough. From now I'll be mad. (Rumi)
