A list of mistakes I've made, and the way to avoid making the same mistake. Feel free to share your own mistakes. 1) Not using all TF2 textures When choosing a texture, enter "tf" under "Keywords." 2) Texturing the entire brush / Texturing things that won't be seen Texture the entire brush with "No Draw." Then bring up the Texture tool, select your texture and Right-Click to apply that texture to a single face of the brush. 3) Using "model textures" on brushes. / Why does my floor glow? Don't use any textures that start with "model/" or "prop/" 4) Texturing multiple brushes that make up one wall-face separately. When you have more than one brush that make a consistent wall, you can treat them as one face when texturing. Clicking on the "Texture" tool will open the "Face Edit Sheet" window. Left click on one brush to select it. Hold Ctrl and to select additional brushes that make up that wall. Click on "Treat as one" in the Face Edit Sheet window and then Right-Click to apply the texture.
