I have been attempting to get characters out of CC3 into 3DXchange.  Then I tried getting characters with 1/10th the polycount into 3DXchange from CC3.
Then I tried getting characters out of DAZ into CC3 into 3DXchange.

Other than one glitch about colour that I've managed to work around. I have one really serious issue.

I seem to not be able to import anything into 3DXchange.  The best I have managed is getting within a few percent of the end and then the message pops up 'Not Enough Memory!'

I cleared down my C: drive so there's tons of virtual memory available.  I shut down every other program after rebooting, and I'm at my wits end of what next to do.

Characters imported range from 5MB to 200MB - it doesn't matter what size the file is, or its format.
