Well that's not what i have done and is not something that i should do because it is a poor way.
What i have done for don't crash with v_ (that maybe work for p_ too, didn't tested) was hooking pfnModelIndex and return OrpheuSupercede if is one of the models that must not be precached.
For world models i pretend to use pfnSetModel, but i don't want to claim that it is going to work fine since i must look better about it into cssdk.
Off-Topic: Did you guys knew that the game has functions stub_PrecacheModel/Sound/Event that are actually fake functions? I didn't looked at it very deep but my guess is that they are pointers for the engine functions. Well, this guest is based on the fact that i didnt hooked this function and when i unprecached v_knife.mdl, it didn't crashed so i guess this function is some sort of mirror of the engine function. But as i said, didn't looked very deep to claim it
