UniCone // float
The probability of a surface emitting light ray uniformly distributed in a cone. The axis of the cone is the normal vector of the surface. The cone angle is given by ConeAng.
Example
#UniCone, ConeAng SurfEmit Shell 1 1.00000 60.00000
The probability is 100% and the cone angle is 60 degree.
