Player stands under map/can't see other player's model

[GmodRPChaos]

I would like some help on my "create multiplayer" listen server. First off, my friend can join the server but lately, his model is not level with the map -- it's like he is walking under the ground and the ground is at neck level! Also he can't see my player model until I am dead! He used to have no problems at all -- this is a very recent phenomenon. PLEASE HELP!!!

Well from all the addons the only one I see that might be causing the problem is "player packs (3)".And about him not being able to see your modeluntil your death-this can also be caused by his specs.Post his aswell.If nothing works you both should clean Gmod.

Well, some player models are from different engines. DO you have CSS and DoD installed..?
