Hello,
I found two problems with cubemap projection in 360 panorama:
1. Bloom have some issue, I think add to wrong corner (Screenshot_5 its top face, Screenshot_6 its bottom face, other faces connect ok). Glare works fine.
2. In the place where two faces join (front, left, top, etc.), when the colors differ from each other, they interact although they shouldn't (Screenshot_7 - its bottom and right face, red arrows show cut place and on Screenshot_8 and Screenshot_5 u can see a problem with this extra thin white line)
All renders saved to .exr
If you need whole .exr render just say a word.
