Removing placeholder models

I’m new to making GMod movies. I want to know whether there is a way to remove the placeholder models for stuff like dynamite, thrusters, emitters, turrets, etc. It seems that there’s a way to do it from all the machinima videos I’ve seen but I’m not sure how.

I hate to bump this thread but is there anyone at all who can help?

You mean like the models they spawn as?

Yes, like how the emitter shows up as a plug, the turrets show up as SMGs, the dynamite as a stick of dynamite, et cetera.
