So, here I made a fridge with 5 skins. Black, White, Blue, Green, Red.
All fridges except white use phong shading. They all have a illuminative LCD panel. Which will be glowing in darkness. You will have to use skin switcher in gmod or for your map you just pick skin in hammer editor. I take all credit for this , and by saying all I mean ALL! I didn’t take textures from internet since they are very simple.
You can use it in your maps or so.
