I'm attaching some sample source code to expose the appropriate server
blending interface to the engine.
Like Adrian said, if you're doing custom player model blending on the
client, you need to mirror that blending on the server or your hitboxes will
not match.

Same way you do on the client, but this time you apply your transformations
to the server side partners of the cliet StudioModelRenderer. It's all on
animation.cpp.

You know, it never dawned on me that that could be the cause of some of
the hit detection issues in my mod.
OK, so refresh my memory: how do I define the transformations on the
SERVER?
Tnx & Rgds...

One thing to remember is that any transformation applied to the model
client side has to be duplicated on the server in order to mantain hit
detection in order.
We had this problem with CS, where the client was doing all the
blendings ( 9 to be exact ) while the server had no idea about what was
going on. Hence the old CS hitbox problem.
