there are two important folders in SVN:
All the shots live here, anim shots usually with the name aXsXX.blend, where X is the act number and XX is the shot number. Light files usually have a suffix light, e.g. aXsXXlight.blend, with other special case suffixes used as needed.
developing ideas for some shots can be here. often not committed to svn
the edit resides here. reelgl.blend is the 'good' one, though it only works currently on bassam's machine, something to fix.
Most assets to be linked into shots live here, or linked to each other. Other than maps *No images* are allowed in any folder.
