This is my “default” viewer config at Nuke Studio 10:
But as i said, i want to fix it at Maya or all my renders will have banding and i still dont know how to fix banding with Nuke Studio 10 either.
The next image is how i see EXR in Maya 2018 by “default”, i dont see any 16, 32 floating option, but Half Pecision is unchecked MR Haggi.
the next image, was… my original render configuration (4,2,1,1,0,0), in fact i was rendering some noise… i didn´t wanted to fight Maya 2018 about noise too, the scene is pretty big and this “low” config was already taking 10 to 13 minutes to render each frame of my HD scene (for me this was ok), raising just 1 time AA or even Diffuse, was gonna take me extra 5 to 6 minutes per frame (i tested this average time before start rendering) so i didn´t care a bit of noise in my scene, just because i was going to use “denoise” at Nuke Studio… but
after this confg produced this horrible banding i raised way higher several times, my last was AA 8 diffuse 8, specular 8 and same way i raised ray deph values… and i did this… just to test if this banding was a “raising” values problem…but after Arnold took forever (days) to render my 5 to 7 seconds raised scene, banding continued to appear; since its an animation i also used lock sampling pattern and lowered clamp values to avoid fireflies, but i already tested this unchecked, i have made a lot of testings… still havent been able to solve banding in Maya 2018.
I´m starting to think i shoud not make scenes with maya 2018 that imply raising light intensity… Arnold´s banding is just wining and for me at least it´s also a render time issue, i know for big studios 15 minutes per frame it´s nothing, Avatar 2 is taking 24 hours per frame, i mean James Cameron is going to lough about my render times or he is going to scream at me… LOL.
i know i didn´t aded an still of the banding, but it will be useless, i test all my animations in diferent types of display, i even test them in my cellphone some times or in several types of TV displays, I know… im picky, but i didnt saw banding when testing single renders; the banding, ramps or waves of lines are more visible clearly in animation and before rendering… as soon as light starts to increase intensity or exposure ( i tested both options), lines start to move across any flat surface, i also tested adding some noise to my flat surfaces textures, the banding is less obvious but banding is banding and i can not add noise to all my flat sufaces, my flat boxes are gonna look like leather OMG just to solve Arnold´s banding, i´m just close to give up and change the beauty of my original concepts for the sake of avoid waisting rendering time.
I hope my configurations are usefull to find why this banding occours and if so to help others with same problem.
