lmg and i made a new patch that we'd like to get into trunk in next bcon1. I'm not very familiar with BI renderer code, so would be nice if Brecht and/or Ton could review. Codereview won't accept it due to changes startup.blend.c size.
http://projects.blender.org/tracker/index.php?func=detail&aid=29392&group_id=9&atid=127 >From the patch description: For "subtractive" passes, such as AO and shadows, it makes compositing much easier when the default background color is white instead of black (no additional masking required). This was a request by Sebastian Koenig. This patch initializes AO and shadow background color as white and then treats ao and shad values in render result as negative influences on full lighting: result -= 1 - color <=> result += color - 1 i.e. OSA filtering uses the (shr->ao - 1) values. Currently that light transformation happens at final pass filtering, but Ton suggested to move this further down "to the shader level". Compatibility code has been added in the form of a new render layer flag "black background", which is off by default and enabled by do_versions for old files, to avoid breaking old compositor setups with compensation masks. Brecht suggested moving such compatibility switches into a separate UI section to avoid clutter. _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
