  problem polyon with alpha channel enabled material reflects HDRI

  Posted by Roy Mckenzie on April 27, 2012 at 3:18 am

  Greetings,

  I set up a polygon plane with an alpha material to crate some perforated metal. The holes the alpha channel creates in the plane reflect the HDRI I have on a sky object, it also does it with the HDRI on a sphere.

  I have a composting tag on the sky/sphere and checked off “not seen by camera”

  I have tried to trouble shoot it with limited success.

  -turned up/down ray depth and/or ray threshold

  -turned off transparency and/or “seen by rays” in composite tag of sky/sphere

  -excluded the plane in the composite tag of sky/sphere

  I have seen other people talking about this problem, but no acceptable solution. Has anyone figured out a good solution to this?

  Hi Roy,

  I tried this out and turning off ‘Seen by transparency’ on the HRDI sphere seems to solve the problem.
