{F109344}Blender v2.71

OSX version 10.9.4

Processor: 2 GHz Intel Core 2 Duo

Memory: 8 GB 1067 MHz DDR3

When 10 or more planes with a fully transparent material are layered on top of each other, they create fully black artifacts when viewed from head on.

  1. Change render engine to cycles render.

  2. Create 10 planes with a transparent shader, color should be set to fully white.

  3. Line the planes up in a row and view them from straight on while in "rendered" mode.

  4. Observe the nasty artifacts that appear!

You can fix this easily yourself: Go to the "Light Path" panel and increase the Transparent Max bounces. That is not a software bug. ;)
