My own custom models are completely invisible

What does your .qc look like?

Place your model textures in \steamapps\common\Counter-Strike Global Offensive\csgo\materials\models\yourmapfolder

Try compiling again after that.

Also make sure that the model is actually assigned to that specific material, you can check this in hlmv (model viewer) and see what vmt this model is assigned to / what vmt it's searching for.

Thanks for all of the replies and help! I really appreciate it

That's because of the paths in your qc, look at it again the game already knows to look in ../materials for materials and ../models for models, you only need to specify directories below these.
