surf said:I cannot understand this. could you detail it a bit more?
Sure. In addition to your surface attributes (Luminosity, Diffuse, Spec, Reflec, ect) you can add textures to each. When you add a texture to the Diffuse, you get a normal texutred object. When you add a texture to attributes like Specular, Reflection, Transparancy, you do so to "break up" those mattes, allowing for more realistic looking results. Scratches, smudges, dents, all those kinds of imperfections needed to got the look you need can be easily done with high contrast image maps, just like you would use for a bump map or displacement map. They act as an alpha channel for each attribute. Animating those textures when they are on the model, causes the attribute they are applied to to be animated as well.
Here is a simple box render:
Here is the texture to be used:
When applied to the Diffuse (with a cubic projection) all sides the same Surface Name, the result is this:
Pretty straightforward. Take the texture off and apply reflection to the whole thing and you get this:
Apply the same image wiith cubic projection again to the reflection and you get this:
It's breaking up the reflection, based on white and black.
Apply it to the transparancy:
you get that. Make the polys double sided:
You get that.
Now imagine animating the texture alond the box. I't s pretty straightforward stuff.
