Curio's Industrial Derelict


	Grill Alpha



	Throughout this guide you will have seen this texture popping up in the example images. It is in fact two small alpha maps. One for bump and one for transparency. I've had a lot of fun with these, and for such a small map, it's incredibly versatile. It works for chain-link fences, metal grill flooring, floor grip, and all manner of other things.



	To make the chain-link fence create a box. Squash it in the X and lengthen it in the Z. Apply a suitable texture to the diffuse and ambient channels, (I used Rust). Now apply the blurry version of the map to the bump channel and set to 100%. Apply the hard-edged version to the transparency channel and set the material to "blend transparency". Now scale the two alpha maps up to something like 80% (or whatever looks best in your scene). Make sure the two alpha maps are scaled to exactly the same size. There's your chain-link fence. You can alter the look of it by either stretching the object or scaling the alpha maps along one axis at a time. This way you can achieve a wide mesh for fences or a tight mesh for floors. You can also use the bump only to create a surface with a "grip" texture.
