Can anyone help me out…I seem to be having a problem with some strange halos under my lemons…They are very nice lemons but I don’t think they deserve halos 
I think light go to much deep in the surface, through the entire volume of the lemons, so there is a yellow light under them, because the light is colored by them.
Do you mean the scatter radius is too high ? Im not sure how else to control the light penetration..
yes, it’s probably the scatter radius. you can try with smaller values.
It seems adjusting the radius and a few other things have resolved the problem. thanks
