problem with material "blackbody emission"

[guigui441987]

Hi,

In my scene i have a lot of material "blackbody emission" on an object and it's working good, but if i duplicate this object or i create an other object with an other material with "blackbody emission" the lighting change. the emission of light decrease.

Why ?

Thanks

Hi,
it's general pitfall. Because it collects to a single mesh. So it will normalize the emision of lighting. Explained many times. Solution is to understand how's the things in background. How's exported to octane structures. If you put a octane object tag, every illumination will be normalized.

It happen if i enlarge or i shrink my object. The light is much more powerfull if i shrink my object and the light is decreasing if i enlarge it.
