Hi OroMatoko!
It seems like you are using a program to convert the standard .gr2 Granny files from RAD game tools.
During the beta, SW:TOR was using the Granny format, and if you still have those beta files, you can convert the models with your tool.
However, in the release version, they developed a new, custom format that is completely different to the Granny format but they kept file extension .gr2 the same.
Together with Privateer's help I was able to figure out the new format and am currently writing a specification of the format; this may take a few more days.
If you know a little bit of programming, you will be able to write a tool from the specification that can read the new .gr2 files and convert them into another format like .obj.
Otherwise, you'll have to wait until such a tool is created. The best way would probably be a plugin for
Noesis but since I do not know Python very well, I do not think I will be able to do it. But of course, anyone who feels up to the task can write such a plugin, and with the specification, that should be fairly easy to do.
