Quote - is there a trick to getting IES files to apply? i've been trying 3 different ones (narrow, medium, wide) & it doesn't seem to make any difference. in the emitter panel, i browse to & select an IES for each emitter. am i missing a step?

Are you clicking on the 'Apply' button to assign the IES file (and the other parameters) to the emitter?

If so, are there any error messages being generated in the Lux log pertaining to emitters?

You might also want to check the Lux scene file - search for 'iesname' and it should find a line similar to this:

"string iesname" ["L:/Poser development/Plop/Pose2Lux folders/IES data/erco_red.ies"]
