It would require decompiling, yes. But since they are both on the valve biped rig all it would require is decompiling the civilian model, then adding the zombie animations (which would be found by decompiling the zombie model) to the QC and recompiling. I don't think you'd have to modify the SMD files themselves. Provided it is on the valve biped and not a custom zombie rig.
EDIT: Re-read your post, if they share the valve biped rig then all you'd have to do is decompile the zombie model and the civilian model, in the zombie .qc file change
- Code: Select all
$model studio "path/to/zombie_reference.smd"
to
- Code: Select all
$model studio "path/to/civilian_reference.smd"
It will either be $model or $body I think. This is off the top of my head, though, and would require some coding to make it a new class or w/e.
