I never did get into Blender, I find the UI (even the revamped one) to be very, not user friendly.. I mean, it's like trying to use Linux when all you've ever used is windows. Like, having to type in commands for stuff that have buttons or dropdowns in Maya. I have used Maya a fair bit, and that's prob why blender is so awkward for me to use.
Sadly I nearly got a character fully modeled and furred, but then my Vray trial ran out, and Autodesk started asking for 'proof' that I actually attended Yale, lol... Since they only offer an educational license to the schools that pay them for it.. I'd have considered at least giving Blender another shot at that point, but I don't think Xgen fur is likely to transfer over too well, and the thought of having to redo all the fur seems like a bit of a nightmare to me..
Btw, sculpting is a fine method for adding detail to your model, but if you plan to animate it, I'd highly recommend converting to polys.
Also, what kinda hardware do you got in that computer?
