Commit: cdd1d5a93c432ddbee8a8e578b0c28781aef71da Author: Thomas Dinges Date: Fri Sep 5 16:17:24 2014 +0200 Branches: master https://developer.blender.org/rBcdd1d5a93c432ddbee8a8e578b0c28781aef71da
Cycles: Initial support for volume ray visibility. This adds a new "Volume Scatter" option to the "Ray Visibility" panels and can be used to e.g. exclude lamps from having an influence on the volume.
