Nasty Blender imports I think happen in Daz.

Prospector

When I load a figure in Daz, get her all dressed,hair on, heels on dressed to the 9s and export with the bridge, her feet get all wonky. (How do people write with mouse ???) Anyways, pic shown is in blender, but problem happens in Daz I think, because when heels are used the feet and body conform to shoes from what I see and body raises and feet heels raise to go into shoes. But on export it starts the export process and the body then drops to floor and shoes go thru floor and then pops back into correct positions. This doesn't happen barefooted or with only sneakers or flat soled shoes.Is there something I am missing to set before export, or is there a way to make the (in heels) position as a base so it doesn't drop to floor?

Thanks
