rty - I may be not reading your correctly, but it seems like you're giving instructions in what is desired, when I'm trying to explain that I already did that. I said that I detect that you want a Lux area light in the mat converter, via the fact that in poser you had ambient turned on. Then I convert that material into a Lux area light material, including the ability to modulate color and gain. This is just a short-term solution until I manage to do the full mathematical analysis of the shader. The goal is to detect what the shader is trying to do, given how you do things in Poser, and then do a Lux version that does that, only doing it the Lux (better) way.

Also, I found this tidbit in the lux thread you linked to. Thanks for the link.

Quote - Also note that if you set the power or the efficiency to 0, then the normalization is disabled and the light intensity per unit surface area will be the same whatever the size of the object.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
