Im fairly new to cs2 mapping and im trying to make a minigame map, but need to make a grenade follow camera like this one from Yprac. Does anyone know what was used to make this or how I could recreate this?

I have no clue what caused this to happen. After I put lighting into my map all of a sudden my doors went invisible. I tried to run the map with no lights, no hints, no area portals, and anything else. nothing has worked so far. I would appreciate if someone could help me on this.

Edit: I figured out it's only door01_left.mdl that invisible, rest are fine.

ANOTHER EDIT: I forgot to uninstall my Gmod addons when testing the map.. I'm such an idiot!

Hopefully I'm not breaking any rules with this post. The map took far too long to make. It's a shameless resident evil ripoff, so consider checking it out if you like that sort of thing.

Hi, I don't have these files in the cs2 folder (I also have CS:GO Legacy installed) or in the separately downloaded CS:GO.

There are no SDK or Hammer files in either of these two folders.

I also installed the CS:GO SDK, but I can't even launch it because it shuts down immediately.

How can I fix this?
