That seems to have done it. Thanks!

So I'm working on this model, and I decided I'd use a pre-made skeleton to avoid the hassle of making a new one. I parent every part of the model accordingly, I create a keyframe for the skeleton, I export it, and everything should be fine now.
Except when I imported the model back into Blender to see if it exported properly, the skeleton had reset back to it's original size. The model itself is still the same size, but the skeleton is now just floating inside the middle of the model:

Does anyone have any suggestions?

So I've been working on exporting a Dalek model from ProjectDalek to Source. The model is divided into segments, so I had to assign the bone parents and weights individually. This also means I have to export each body part seperately. For whatever reason, two of the model's segments just flat out refuse to export into SMDs, and I'm greeted with this error message for both of them:

I'm not doing anything differently with these two segments that I've done with every other segment I've managed to export. Is there something I'm doing wrong, or is it an issue with the model itself?
