OK, this is bugging me me for quite a while now:
in the DS plugin the brightness of an emissive object is dependent on it's size and not it's energy, which is, as far as I know, not physically correct, and makes it impossible to do a physical correct scene lighting: if I want a 100W light bulb and I convert an existing mesh as emitter or place a sphere as proxy, the radiant intensity is dependent on the mesh size and not Watt value.
I made a quick comparison between Poser and DAZ (both the same scene, only the size of the emitter is changed)
Poser (scale independant, physically correct)
DAZ (brightness depends on emitter mesh scale)
Emitter values are in both applications and all cases the same:
Is there a setting I'm missing or is this a bug?
