| Normal map creation, diffuse map creation, specular map creation and finally application of the texture maps onto the model in Oxygen. Modeling or UV mapping is NOT treated here but can be learned through a bottomless pit of tutorials that can be found online. Normal maps are treated first because as with many next-generation games, the normal maps account for the biggest percentage of detail information for the model. For your creation to stand out, however, you will need a successful combination of all 3 types of maps. The flow diagram in Figure 1 represents the pipeline for texture production for the example that will be treated in this document. The example that will be shown is that of a creation of an armored vehicle texture. For the simplicity of the explanation, the object to be textured will be a 1x1m plane. This will let me focus more on the texturing side of the text. Before anything can start you should make sure your copy of Photoshop is equipped with the nVidia Normal Map Plug-in which can be downloaded for free [[http://developer.nvidia.com/object/photoshop_dds_plugins.html|here]]. This plug-in allows to convert black and white height maps into normal maps. Some may choose to use an alternative like [[:editing_tools#image_editing|CrazyBump]]. The point is, just use whatever suits you best. Once you have the plug-in installed you are ready to begin. | Normal map creation, diffuse map creation, specular map creation and finally application of the texture maps onto the model in Oxygen.
