Have any of you ever seen this error when trying to build and preview a file in the Asset Editor?

At first, I thought it was corrupt part in the IGS file, so I went back and removed parts one-by-one until the error went away. I then went back to the original 3DC file and "detextured" parts until the problem went away. It turned out that 3DC, or the Asset Editor, doesn't like the texture I was using. But what would make a texture "corrupt"? Also, it seems as if this error were related to the way material properties were applied to the part. However, textures were applied to the entire model without using any sort of shader, so the "TexDiff" part of the error is puzzling.
