I need some basic assistance with IES settings.
1. Should the blackbody power setting always be left at 100, or does it need to change to match the lamp wattage?
2. The power setting under the IES defaults to 0.9. Should it be left at this value?
3. Should the efficiency be set to the actual lamp efficiency or should it be set to some other default value so the IES file governs?
4. Are pitch, roll and yaw relative to the emitter mesh or the model coordinates?

Thank you,
Greg

here's a tutorial ablout IES lights

Thanks. Great video.
I noticed in the video that there was a lot of adjustment of the power and scale settings to achieve a certain effect. Are there default settings for power, efficiency, etc. that use the IES file in its real world state, i.e. to be most realistic to the actual fixture and lamp performance?
