The model is models/props_junk/PushCart01a.mdl

It shows up in hammer, but not the map. I really don't know what the problem is, so I am asking to see if any of you would know why.

No clue why, my prop_statics don't show up either, making them prop_dynamic worked for me. No idea on the performance difference though.

Well its not a static prop for starters. Use its on prop_physics_multiplayer instead.

Yes, only use prop_static's on things you're POSITIVE don't move. Things such as pipes, fences (not all) etc. If you look in your compile log you will find something saying the model (whatever it is) isnt' a prop_static, but a _______ (prop_physics in your case) and if you can't find a prop to use it with, use prop_dynamic_override.

it might not be in the dods folder and cant find it,so try moving it to the dods folder.

Check the start fade and end fade, and type: 0, or create sky.
