Hi,

It might be related to a high density distribution generating many overlapping objects and increasing Global switches - Max transp. levels (default value is 50) should fix it (sometimes may be necessary to modify Secondary rays bias also).

Anyway, please feel free to send us your scene to check it here. Thanks in advance.

Best regards,

THANK YOU !!!
the max transp levels value was 999 so i was totally lost, but the second rays bais was set to 0.00, i set it to 0.002 and it seems to be good now.
you saved my rendering process!
