So you are saying that every time you export anything you get an error about geometry data?

Have you updated Blender yet?

Your file doesn't contain any groups. Do you mean that you clicked "Scene export"?

You can start by upgrading to the latest version of Blender. Then please tell me which object you are exporting when the error happens, because I still have no idea what you did to make the bug happen.

Everything works fine for me. What version of Blender are you using, and what version of the Tools?

When I asked for the type of object I meant Blender object, e.g. mesh or surface. I still don't know precisely what you did to trigger the bug.

Geometry data would normally mean a 3D surface. Please post the complete error. What type of object are you trying to export when the error occurs?

I've rewritten the whole system to avoid having io_smd_tools.py in the first place.

That's a UI bug, sorrry! You need to clear Engine Path, set the Export Type to SMD, then set the Engine Path again. That will be fixed in the next release.

There was a changelog note...it was just ages ago. :-)

It's a fair point about saving user prefs. I want to save the old add-on being disabled, but of course any other changes are saved too. I'll just remove the save call; in most cases the user will do it themselves anyway. The worst that will happen is a "missing add-on" warning on the prefs screen.

io_smd_tools.py in the old filename of the tools, back when the whole thing was just one file.

The only job it has these days is deleting itself so that you can't have two versions installed. That's initialised at io_scene_valvesource\__init__.py line 38. Is that script not running?
