I’m here for some information about this model format,its extension is YOBJ.I’m providing a sample model file and textures below.
also here is a blender script which opens the model in blender 2.49
Unfortunately this script doesn’t export the model back to the same format after editing.

I need some expert to shed some light on the face format and the U-V data
here are some details of the format which i know
