I finally got around to trying out the 3D support built into Photoshop CS4 extended (I don't have CS5 yet), and was pleasantly surprised at how easy it was to use (compared to "real" rendering software such as in modo or Lightwave). It's renderer can't compete with modo, LW or Octane, but for simple illustrator type projects, it's not too bad.

So, after fiddling around with it for a bit, I decided to try importing a MoI model into PS, and was again pleasantly surprised at how straightforward it was. All of the MoI styles came in as PS materials with no problem:



After that I had a little fun doing some typical Photoshop stuff, including painting some surface textures, and ended up with the following doodle...



Overall, it seems like a fairly straightforward workflow that fits in well with MoI's catch phrase: "3D modeling for designers and artists".
