I suspect what I need the DSON Importer to do, to properly optimise it for my requirements, around content heavy scenes, is to have an option to remove all unused Genesis morphs from the "virtual cr2" it builds...

just a guess, but I suspect the memory problems are due to it loading the whole Genesis stack, as installed into the "data" folder, into each Poser Genesis cr2 / figure definition that gets loaded into a scene?

it strikes me that such an option, to easily turn off unused morphs, at source (the DSON Importer Genesis data parsing / cr2 building routine), could be one of the fundamental benefits, even, that this dynamic / virtual cr2 system could deliver?

Of course, such an option, to exclude all unused morphs when the DSON Importer recompiled an instance of a Genesis figure, would need to be accompanied by a reciprocal function, to re-include all.
