when i switched to hammer++, the map compiler crashes within a second of starting even when running an empty map. I've been posting about this for the past few weeks and i still have not even a clue as to what is happening.
Ever since I downloaded hammer++ my compiler crashes within 2 seconds of running. I've even tried compiling a new empty file and it immediately crashed again. I've looked at multiple tutorials and have checked all my files, but everything seems to be in the right place. I really don't wanna go back to using hammer and I'm about to just give up.

Can somebody explain to me how to safely download hammer++ because last time i tried using it i lost almost all of my maps.
I have no clue if this is even possible given how stupid this editor is but i dont know what else to do
the file itself is saving but when i try to play it on gmod nothing has changed now
hey does anyone know how to make different sky parts show different skyboxes?
For some reason this isnt doing anything. it just puts a sky around everything and i can see walls on the other side. can somebody give me an actual solution that doesnt involve rebuilding the entire map?
