Oh seriously good stuff :)

OK this is what I would do.... create a single CR2 with all the morphs in it. Very flexible and no messing around with injection poses. 4Mb aint so bad. Now in your readme ... right at the top... in VERY big letters tell folks to- Load the column figure into a scene and get it just the way they want it.

• File/Export the figure as an OBJ ... only box that may need to be checked is weld.
• Now delete column figure from the scene, (or move it) and reimport the column.obj (no boxes checked except maybe weld)
• Repeat as required.

You now have the advantage of flexibility without the overhead of many large column.cr2 files in the scene, or a confusing number of files in the figure library.

Hope this helps 'cos this project looks exceptionally good :)
