really nostalgic map

I dont have the mappack Im looking for it as well

That exactly was im looking for, can you upload somewhere full pack of hl2dm maps? because it's so nostalgic, i was playing in old gmod in 2008-2009 and there was a hl2dm map pack, this map was in the pack, but it's lost, and im still searching internet to download it, but im afraid of viruses or something like that, so, can you upload hl2dm mappack somewhere? that would be awesome.

i have some missing textures, cubemaps i think?every reflection looks pink. can you help me with that?

can i spawn blocks in menu?

For a quick fix, just go into console and lower sv_gravity. It's most likely a problem with your addons, the low grav works fine for me.

well ok then sorry I cant help you

Sorry, I won't disable anything, because I have at least 800 addons and some of those are disabled so I won't "ruining" my game! Sorry... :|

disable all addons and then try, if its still normal gravity tell me and i'll update the map with a fix

I meant, I loaded in the map, grab one block and I let it fall, but it just falled as fast as the default gravity. And I tried to jump, too, but I can't jump any higher than the default gravity. So, actually the gravity isn't any lower than default or one of my addons is modifying the gravity...

gravity is lower i checked, at default gravity you cannot jump over the flying blocks

Definetly it isn't "low gravity", actually gravity is completly normal. Please check.
