I'm currently moving house, but I'll look at this when I'm next able.

If you look at the QC you imported, it should have a line saying "$origin". Place the camera at that position.

I don't know how to compile viewmodels specifically, just look online.

The easiest way is to create a Camera object at the right location. That way you can switch to the viewpoint easily. Change the Camera's field of view settings until they match the game's.

This is happening because your armature is hidden. I'll put a fix out later, for now just unhide the armature before importing.

By scene I meant .blend file, sorry. Upload it to http://www.pasteall.org/blend/.

Can you upload the scene and the SMD you are trying to import please.

Thanks, I've pushed this fix to the Git repo. It'll be in the next release.

Your armature is offest from the origin, but by design the exporter ignores the transform of all root objects. You can fix the problem by making the mesh a child of the armature, or by adding an non-exported empty object as the parent of both.

The model you're exporting is completely unsuitable for a collision mesh.

You're going to have to handle conflicts like that yourself I'm afraid. You can import the animation separately and copy the bone across if it's missing from the reference mesh. But I suspect that those models are quite severly out of date by now!
