I rendered attached .pov file with both 3.62 and 3.7RC1, and got different output between them.
In 3.7RC1, it looks like no_reflection option of the black sphere doesn’t work.

This task depends upon

  • Field changed: Summary (rendered image different between 3.62 and 3.7RC1 → no_reflection broken)
  • Field changed: Status (Unconfirmed → New)
  • Field changed: Category (Backend → Texture/Material/Finish)
  • Field changed: Severity (Medium → High)
  • Field changed: Priority (Normal → High)

From some toying around with the scene, it seems as if POV-Ray is forgetting that it’s tracing a reflected ray when the ray passes through a (semi-)transparent object.

Tested with 3.7RC3+ (up to #5402), rendered picture is now like the 3.6.2 one.
