Does anyone know how to get around the darkening of the areas where two objects overlap each other?
Of course they do not intersect each other but it seems unnatural.
When objects appear separately, they do not absorb light as much.
I'll be grateful for any advice.

Hi shperical,

What kernel are you using?
Try increasing the max depth (or specular depth if you are using direct lighting kernel).
Are you using absorption or just altering the transmission color?

Edit: Another thought is to try decreasing the ray-epsilon.

Thanks
Chris.

I owe you a beer
Ray-epsilon helped

but I increased it from 0.0001 up to 0.0064
And the kernel is PMC.
