@czak the map creator needs to add env_cubemap and run buildcubemaps. in the meantime you can fix it by disabling reflections with mat_specular 0 in the console.

Yes, skybox from CS:S

map is good, however my revolver and props i spawn (ovens for example) are shiny. the same is for the metal fences on the bridge

@loading... I think the skybox is from CS:S

great map, small but effective design, although for some reason the skybox is just black? is the skybox texture from a game i need to mount? if not could you link the addon where you got the skybox texture from?
