Model doesn't spawn.

I made a small headhack just for fun and in Model Viewer all looks good. But in game model spawns invisible - it has weight, etc. but absolutely invisible. What I did wrong?

Material paths, I think.

if you check the console and it says MDL cache failed to load VVD. its an abnoxious error i belive with he engine of some sort but usually is only for models, i have it to i cant downlaod any models anymore because of it they all show up invisible

That looks like Ivan the Space Biker.

Here is the solution - I see a lot of messages like this in internet. You should just check your path to model, it should be the same as you wrote in .qc file.
It took a whole month to understand. :v:
