This will be fixed in the next release.

I didn't know that. It shouldn't be a problem to support this.

The imported armature is named after the DMX file. That was done to make it clearer where the import came from, but I can see now that the lack of round-tripping can be a problem. I'll look into it.

Yes, this has been fixed for the next release. In the meantime sharp edges will do the trick.

Thanks for drilling down on that, I wouldn't have spotted it myself. This will be fixed in the next release.

If you don't have a file at common\<game>\bin\studiomdl* then you can't build models on Linux.

For Linux development I would recommend Unity.

Still can't reproduce the error.

It's a strange error too: it says that Blender needs to be in object mode, but it is put into that mode (or rather pose mode, which works too) immediately before the exception is thrown. Yet your screenshot shows that you are in edit mode for some reason.

Try closing Blender, deleting/renaming the folder %appdata%\Blender Foundation\Blender\2.69, then reinstalling the Source Tools and importing again.

Could you upload the file for me, please.

I can't reproduce this at all.

You say that you are importing scout_morphs_low.dmx, but the SMD importer is running (not the DMX one). Are you sure that's the name of the file you're working with? Is it one of the files under sourcesdk_content\tf\modelsrc\player\scout\parts?

Don't see why it would. Try it and see!
