Didn't take it as disrespect.
BTW it only looks complicated, it is really simply saying A times B where A & B are matrices.
Btw there are also matrices that can be set for skins. They control what color channels and how much are used for what effect. With the _S _E system the matrices are created automatically but you can over ride the defaults.
For instance it is possible or only have a spec channel, and then have your environment be 25% of the spec channel. Or simply set all the env or spec to a fixed number (like a texture of 1 color).
The File name is xxx_NEP_MATRIX.txt or XXX_MATRIX.txt
it is set up as the following
A0 Is alpha channel of texture 0 base texture
B1 is Blue channel of texture 1 _NEP Texture (Normal Env Power)
IN CHANNEL
A0 1.0 0.0 0.0 0.0
B1 0.0 1.0 0.0 0.0
A1 0.0 0.0 1.0 0.0
1 0.0 0.0 0.0 1.0
S E P A
S is Spec
E is Env
P is Power
A is alpha
In this example Spec = A0 * 1.0 + B1 * 0.0 + A1 * 0.0 + 1 * 0.0 = A0 * 1.0;
In this example ENV = A0 * 0.0 + B1 * 1.0 + A1 * 0.0 + 1 * 0.0 = B1 * 1.0
In this example POWER = A0 * 0.0 + B1 * 0.0 + A1 * 1.0 + 1 * 0.0 = A1 * 1.0
and Alpha = = A0 * 0.0 + B1 * 0.0 + A1 * 0.0 + 1 * 1.0 = 1 * 1.0
to create the matrix file for the p51d teture set the file would be named p51d_NEP_MATRIX.txt
and would contain
1.0,0.0,0.0,0.0
0.0,1.0,0.0,0.0
0.0,0.0,1.0,0.0
0.0,0.0,0.0,1.0
