TEXTURING

After all that it's finally time to dive into some texturing. Dave Wilson (author of Texturing 101) helped me considerably in this section. Firstly in the surface properties of the edititable mesh (3D Studio MAX) I'll divide up the missile into multiple material IDs depending on the surface texture I want it to have and the angle the polygons are faceing, for different mapping types. For the main texture of the missile I used a cylindrical mapping. I use a plug-in called Unwrap Texture Object which exports the mesh to an image that can be imported into Photoshop. Once in photoshop I imported the mesh image for reference. Dave helped me with the initial texturing, he took an image of metal plating for a base texturing, then added all sorts of dirt, sunspots and decals. I then took over and added straches and weathering to the missile using the mesh as a reference to where they would be.

The most important part of the texturing procedure is to keep the texture map in layers. This means after you've finalised the RBG texture map, you can desaturate, then change the brightness and contrast of the layers to create your bump and specular maps.

I'm not going to explain all the texturing because that will that quite some typing :). Basically the rest of the objects varied between texture maps and procedural textures.

RENDERING

To show off the model in all it's glory I wanted to render an image of it in "Radiosity Land". Unfortunatley 3D Studio MAX doesn't come with out-the-box global illumination rendering software. So what I had to do was improvise, instead of lighting an entire scene with one light I'll do it with 33 :). Below is an image of my scene

1208_tid_lit-scene.jpg
To start off the explaination, I have two scene objects. The round globe is an inverted sphere with a very white blue self illuminant texture. The ground plane is a simple plane with a matte orangey brown texture. Now on to the lights. Above I have 9 angled whitey blue lights only giving off diffuse light (no speculars). Each one has a very low intensity, so they don't flood the scene with light. The same goes for the bottom 5 lights, except they are of a light orange colour. The whitey blue lights give the GI (global illumination) effect of the self-illumanant sphere and the orange lights give the GI effect of the ground bounce. The main light source comes from an array of 20 lights. What this accomplishes is the soft shadows you get with real lights i.e. the further an object is away from it's shadow, the more blurry the shadow. Below is a close up on the array.

The lights have a path contraint to a circle. This way as I'm tweaking the shadow's appearance I can easily change the radius of the shadow blur by changing the radius of the circles. Since there are 20 lights the intensity has to be incredible low so that they don't flood light. Also to increase the illusion of global illumination, I took the specular maps for all my objects, and used them for the intensity level of raytraced reflections.

Well after all that, have a look at how it all came out below

Cool huh :). Below is a wallpaper I made from the above image with added photoshop effects. You can download the fullsize image (1152x864) right here.

And here is a moody lighting render of the Coyote missile. I used two lights, a shadow casting main blue white light at 1.25 intensity and a orange backlight at 0.6 intensity.
