Here's one:

Can anyone tell me how azimuth and elevation are parametized in Maya?

The reason that I want to know is that I want to connect the U&V position of a light on a surface sphere with the position of the sun on the shader. So here's the network:

SkySphereShape.worldSpace[0]>closestPointOnSurface. inputSurface

Light.translate>closestPointOnSurface.inPosition

now the closestPointOnSurface returns a U&V co-ordinate which denotes where my light is across the surface , 2 floats with a min of 0, max of 1(because they are linked to the surface:p ), so I'm almost there, but, the numbers for azimuth and elevation are meaningful outside of (0,1)....so I want to know what constant I have to multiply by to make the movement of my scene light link up with the shader sun....

Anyone?
