So today I was working on a Tf2 map when I decided that I wanted to make a custom texture for it but when I tried to do it it wasn't working at first it wouldn't show up but I tweaked with it a bit but I got it to actually stay in the materials list
"LightmappedGeneric"
{
"$basetexture" "mvm_fort_mann/road_1"
"$bumpmap" "mvm_fort_mann/road_1_nor"
"$surfaceprop" "tile"
"%keywords" "tf"
}
