Hello, i have strange black pixels / dots / holes / artifacts in my renders, it happens randomly on the rendered sequence.
Scene specs :
- Mtoa 3.1.1.1 and Maya 2017 update 4
- animated camera and animated objects with geometry cache
- lighting with a skydome light and an hdr image
- Samples : 6,4,4,2 ( tested with 8,4,4,2 also)
- i tested changing the hdr image but i still have dots at the same positions
- i tested lock/unlock sampling paterns, adaptive sampling on/off, increasing diffuse/spec samples but i still have black dots / spots / pixels randomly on some images
- i tested decreasing the filter width, it reduces the spots size but the render looks noisyer
- i tested with locked camera also
- spots seams to appear on the indirects AOVs only
- spots are not affecting Alpha channel
i realy have no clue on what is happening.
Can you please help? 🙂
Thanks
Have a good day
