Hi! Dougal2 when using an ies light how do you adjust the power of its light? do i adjust it at the ies shader incandescence or do i need to scale my model to meter unit?

Or increase the glowIntensity of your meshlights up to several million (or so, I don't know what the value is, but keep adding zeros until it works).

Do you mean there is a mismatch with the wiki ?

roville: if you set incandescence values under the 1 1 1 range, it will become a RGB emiter. Between RGB and blackbody stands spectral emission (range 250-800 roughly).

Your later suggestion about scaling the scene to real size (setting mti_GSF to 1, 1m = 100 units, keep units cm) sounds a good approach. One can't change IES values but in the text.

ARAARGGH!

Sorry, I've been using an old version of MtI.

The wiki is correct.
