VrayFur 1.5 explanation?

can anyone explain how the new vrayfur RGB mapping work? Nothing yet on the help section.
I understand how the ‘mono’ work, but no idea for the ‘rgb’

just make a small test with gradient ramp… the first image i put a simple gradient ramp map into “bend directional map” slot. The second image, in “initial direction map” slot.

I assume the RGB matches the Max internal directions as such:

Red is X
Green is Y
Blue is Z

Mixing values will push things in different directions… the refferential direction is probably the normal (Z being perpendicular to the face). I bet maps for VRay Fur behave very very similar to normal maps.

Isn’t it X=Red and Y=Green?
That’s the colour coding I have in my version of max.

You’re right, my mistake.
