[Bf-blender-cvs] SVN commit: /data/svn/bf-blender [16176] trunk/blender/source/blender: a) Forces can be hidden by deflector object now ( need to talk with jahka about particle integration - should be copy-paste) see http://dldw.de/tmp/index.php?file=w2.blend ( press play button in timeline and change the absorption value ob the cube) b) fixed deflector/collision bug with continues physics c) cloth wind/ forces uses masses now d) even faster collision object gathering e) have fun ; )

Log Message:
-----------
a) Forces can be hidden by deflector object now (need to talk with jahka about particle integration - should be copy-paste) see http://dldw.de/tmp/index.php?file=w2.blend (press play button in timeline and change the absorption value ob the cube) b) fixed deflector/collision bug with continues physics c) cloth wind/forces uses masses now d) even faster collision object gathering e) have fun ;)
