Did you remember to delete the associated .bin and .dbo files for
your model after modifying the FPE?
After any modifications to the FPE file (or the .x file for that
matter) you normally have to delete these two files in order for
your changes to show.
In the same way, if you modify or save a texture file in .tga
format then you need to delete the associated .dds file.
Basically, FPSC creates the .bin, .dbo and .dds files from the
.fpe, .x and .tga files and therefore doesn't see any changes in
the original files if these "system" files are left in the folder.
