For DX8 programs, the will always input registers look like this: v0:
|

position, v1: normal, v2: color, v3: texture coordinates, v4: texture
|

|
|
coordinates 2 if available.
|

For DX9 programs, you can manually set the registers using the dcl_

|
|
statements.

callback method for multiple materials and distinguish between them

during the call.
