[Bf-committers] Component Group Proposal

Wed Aug 18 01:30:49 CEST 2010

Hey Joe,

As far as I know, this is currently being put off until after the next stable 
point release since it is not a high enough priority right now. In addition, the 
word I got from Matt Ebb is that there's currently no UI framework in place to 
properly implement it (i.e. multiple hierarchical layers), but in the long term 
I think this would be very helpful since we could have layer groups for 
painting, as well as properly overhauling Blender's layer system (at least on 
the GUI side). If it needs to be done, I'm probably available to create a design 
doc for it. Being an artist, obviously I can't get too technical.

Let me know if you have any questions,

-Brandon Phoenix

I'm bumping this thread, was any consensus ever reached on this topic?
