Cubemap issue after using mat_specular 0 - Developers

i have pink and black reflections all over my map the textures themselves are fine but i can not seem to build cubemaps to save my life, i have done the cubemap making steps listed everywhere about 100 times -mat_specular 0 -map <mapname>(Load your map) -buildcubemaps -mat_specular 1 -disconnect -map <mapname>(Load a different level; clears texture cache) -map <mapname>(Load you map again This does nothing that i can see Anyone have any ideas? i have tried using painted, night, and the borialis 1 skybox, all did nothing to help my issue.

Cubemaps can be a bit weird and methods differ depending on if you are using HDR or not. If you haven't already try using some of the methods on this page. [URL="https://developer.valvesoftware.com/wiki/Cubemaps"]https://developer.valvesoftware.com/wiki/Cubemaps[/URL]

you could try not deleting the default reflections and running without mat_specular 0, works for me

the issue seems to be non existent on my personal computer (makes for pinpointing the issue near impossible.. ) i have tried all of these steps in that link, the thing is the map (with very few changes) worked fine before one of the things i changed was the skybox, it use to be WAY to big (almost the size of the map itself) and i figured i would just rebuild it. it is now just a bit larger then 1/16th the map size (defualt value i believe) it is basically just a black empty box due to the fog on the map (there is heavy fog and in order to make it look good and still have the cutoff i have the fog in the skybox as well. i have tried about 100 different methods and the only thing i can think of is maybe there is something wrong with the map itself. (though like i said i changed very little) i read somewhere that a name 30 in length will break it but the map name is zombiesurvival_gone_v10.bsp (27) should i shorten it? also why would the map be fine on my computer but broken on everyone elses? (they are not missing textures just the reflections [editline]4th December 2015[/editline] maybe i should reinstall garrysmod and compile with a fresh install.

i have replaced all of the custom textures i had, and increased the size of the skybox a bit more compiling now Next i will try compiling with a different version of hammer (since gmod hammer isnt even really needed unless im using painted skybox) if that doesnt work then im out of luck i guess, no idea what is going on.... [editline]4th December 2015[/editline] is there a way to compile without cubemaps being generated? i dont need reflections on the map, its a dark rp map that doesnt even show reflections anyways normally

The issue was i was using the gmod hammer, downloaded the source sdk mp version and it worked perfectly
