After days of tinkering in MAx3d I begin to remember what it was to import a quake1 model.
One is to find the right dxf exporter with quads.
HDXFEXP Export PlugIn

Then after boning the model it seems as if the attachment won't bring up an animating scene.
The bones animate, the model also, but the animation bar won't respond.
It seems I can't make keyframes odf the imported mesh.
So I'm saving every frame for free, which is a rather long way for a pose.
But yes, I can add new models to an excisting original.
