Can't see Half Life 2 props while IN Half Life 2 / Gmod

[Staneh]

Hey guys, I got a small problem here, I just installed all my half lifes and gmod, and, I can't see some HL2 props, like, playermodels, ragdolls, some props, anyone knows why? I tried reinstalling HL2 already but it didn't work.

Are props like black?

[Staneh]

No, theyre errors.

Did you make sure to have HL2 checked off in Extensions? Have you started up HL2 at least once (successfully)?

[Staneh]

Yes, I did, but, I fixed it already, by extracting the "source models.gcf" to garrysmod
