From 21a7433faafed266b48601d44d6aaf80ea66450b Mon Sep 17 00:00:00 2001 From: Sergey Sharybin Date: Thu, 28 Aug 2014 18:58:21 +0600 Subject: Fix T41473: Cycles volume rendering is too dark The issue was caused by the changed defaults from the Cycles side. Because of those properties being saved as an IDProp and not being saved to the file, every change to the defaults would ruin someone's day updating the values. Added a bpy.app.handler.version_update which is run after the regular do_versions() are done and could be sued by the scripts to apply versioning code on their settings.
