I'm new to mapping, working on my first map. I downloaded Youme's Blue and Red Dev texture pack, and I searched my Steam folder for a while looking for where to save them. I even searched my steam folder for what I thought were the names of the default textures, but couldn't find where they were saved. I eventually just dumped them in some materials folder around /***/team fortress 2/tf/materials. Now they can be found in the texture browser in hammer, but only appear as a missing texture, pick and black chequered. Can anyone please help out a newbie?
