Hi,

Setting an IES file to a PointLightSource and orienting / aiming it at a target is covered in this video: http://www.youtube.com/watch?v=i1cx5-2GcM8

If you're after gobo effects, you'll need to place a Face with a masked / alpha texture applied through which the light will shine.

mi problem is the projection light has a uniformity of 95% over the projected surface
masking a light source with out a specific IES doesn't give me an accurate uniformity
what is your thought

Can you expand the question - I'm not sure I understand.

Can you not choose an IES file for a projection luminaire?
