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

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?

No, theyre errors.

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

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