Wasn't there an import of The Doctor and Ace?

There is a Doctor and Amy Pond, but no Ace that I can see. I thought DM did it, but I might be wrong.
hey, i'm having a few issues with some of the meshes. the doctor and the dalek are both completely textureless, and the cyberman is just a white cube
Try using EZ nifconvert when you get the square cube thing, that may fix it which is on alexff.com
