this was the VMT before:
"LightmappedGeneric"
{
"$basetexture" "vgui/ttt/icon_sng_bomb"
"$translucent" 1
"vertexcolor" 1
"vertexalpha" 1
}
then I changed it to this:
"UnlitGeneric"
{
"$basetexture" "vgui/ttt/icon_sng_bomb"
"$translucent" 1
"vertexcolor" 1
"vertexalpha" 1
}
and that UnlitGeneric fixed it :D
