Here's the confusing part. When I build the set in ASP, using images output at full scale from the aforementioned PS file, and I then import the character... he's exactly 1/3 too small. i.e., I have to scale him UP to 1.5 for him to be correctly scaled with the set.
What the heck is going on here?? Anyone know?

Thanks in advance for any help offered!
Brian
Edit: both files (the character and the set) are set to the same dimensions as well.
