I'm going to geek out for a second. I hope you don't mind.
We've featured these spinny pony models before, and they've always been very impressive. Tonight, we have some more, this time featuring our favorite princess pair. KP-ShadowSquirrel continues their march towards distracting us all to death with magnificent 3D pony plot with a Celestia (in both stereo and regular versions) and a Luna.
The Luna one details that these are made with Maya, ZBrush, and After Effects. I'm assuming they're passed through in that order- that the base model is done in Maya, refined and detailed in ZBrush, brought back into Maya for some final rendering, and then composited and prettied up in After Effects. I've used this workflow before, so, take my word for it that these are really impressive. Drop whatever you're doing and go take a look. They're magnificent.
