I am running windows 7. I just bought iclone 4, 3dxchange 4 and the daz fbx exporter plug in. Quite an investment for something that so far I can not get to work! It exports from daz great. But as soon as I try to open the fbx file of a charachter in 3dxchange 4 it just hangs on importing (once ran for two hours and never got anywhere!) Have tried this with several different files I bought specifically for this purpose and no sucess. Unfortunately reallusion also does not seem to have any technical support to call? I find this very disappointing that you can sink hundreds of dollars into their product and then they expect you to way 2-3 days for their first email reply? When I had a problem with Daz I just called them up and they were very helpful on the phone. I really want to use this program but if I dont find some more support I am wondering how easy it will be to get a refund!Any help would be appreciated...
