There appears to be something about the Tera Online .psk files that is different from those pulled from other UT games. I know that Actor X can import these with a little manual work, but neither the Blender .psk importer, nor Object Converter 3D can read these .psk files - both error out. Those of us without 3DS Max are outta luck currently, unless I'm missing something.

Is there any documentation about what's different between the Tera online .psk file and others? If there is, I can likely modify the Blender .psk importer to work for the Tera files. I may be able to figure it out just by debugging the existing script, but knowing what was different would greatly shorten the time expenditure.

Thanks for any information you have.

Well, turns out it was a pretty easy problem to solve. I'm attaching the fixed version of the Blender .psk importer:

The full script is at the bottom of the post, but there's really only one change - at line 531, you have to check to make sure that the len(bpy.data.textures) is greater than 0. If it's not, the code will error out with an index out of bounds.

Hope that helps somebody.

That's not TERA or umodel issue. That was a problem with Blender script (what you've fixed).
Moving thread to the common board.

Fair enough. Thank you for moving it.

In my defense, though, I didn't actually know it was a problem with the blender script until I had debugged it. TERA .psk files also cause errors in other programs like 3dObjectConverter, and I've never had problems with .psk files from other programs.

Hi guys. Just found Blender importer on GitHub - one guy is extending the one posted in this thread
https://github.com/Befzz/blender3d_import_psk_psa

Might be useful for someone.
