Hi Mario,

thanks for your input on this relative-path issue and the flt loader.
I cannot really say *why* textures and external references are not
searched relative to the model location; we will consider adding
this functionality in a future release.
No, source files for the flt loader are not available.

The best solution I can think of in your case would be to set a
separate pfFilePath for each model you load..

Best Regards,
Paolo
