Hey Charly .... did you have to increase up to 8 'bounces' of GI ?

Please be patient with me ..... I don't always 'get it' the first time 'round - not even the 2nd time! :(  - yikes! ...

I've increased  to 20 but still have a black eyes . I'm looking for another solution to avoid that 


     

With this charming lady, just one eye is black, but the time render is about 60 70 sec, and bounces at 20, and i have some noises, it's complicated Sonic :-)


     

My problem is now this "maudit" black eye because I think that 60 sec of render time is correct if I consider my config ( I don't have the GTX 1080)


     

Yeah Charly ....
As far as I know, the 3 things that might help with dark eyes are:
● Better Lighting
● More GI bounces
● More iterations (render time)

Edit:
Charly - try this:
● set your GI bounces to 8 or higher
● set your de-noise to 148
● set to 150 iterations
Don't do any limit on time .... let it run the full 150 iterations ...

thanks Sonic but still dark :-)


     

I got it Sonic :-)


     

Hi Charly, seeing that you seem to solve the problem already. Assuming you did not have IBL light on, got the same black eye with just spot on.

Yes Brand, i've got IBL on but too low, i 've just increased IBL and no more dark eyes,In anycase,  thank you guys


     

Now that I tested, I notice that the eye turns black when a light is directed directly to the face.
Perhaps something strange with the eye material or normal for Iray or maybe a bug? Got a lot better render without light, a little strange that you have to set up IBL in two places though.
