Hi micmac,

Can you share some more info? Were you saving to file and it didn’t work, or it didn’t work in the VFB view? Was in enabled for every LightSelect element? Can you share some images of the Beauty and the LightMix, or even the individual LightSelect element renders (you can select each from the VFB).

Thanks!  
Tom
