Quote - @randym77 Yes it does, but it is extremely fast in DS. Loading time on a figure with all my Genx transfers is like 10secs max. If they can get that speed in Poser we all good.

I think DS4.5 must implement some form of caching system (an on-the-fly morph baking system perhaps) that is not (as yet) present in the DSON Importer system...

...such a feature would quite possibly have to work very differently in Poser, internally. So I'd be inclined to suspect they haven't been able to just rip that code out of DS4.5 and stick it in the DSON Importer?
