It is quite understandable but still a few things bother me. for example.


#local perp1 = VPerp_To_Vector(pos);

perpendicular vector? from only a single vector?
A concept that is very strange to me.
Is that one of infinite possible vectors of the circle?

I can echo results and try to figure the logic, would be nice if the help
file said more than it does on this one.

now this makes sense:
#local perp2 = VPerp_To_Plane(pos,perp1); (vcross())


And I was thinking of using radiosity, but seems it doesnt need it and/or is
doing it anyway with this method. slow render but worth it for sure.
