If you can get 3DWS to export to 3DGS directly, I'd purchase in a heartbeat. You accomplish that and I'll wager you'd have just about every 3DGS user beating a ath to your Paypal (or whatever you use) account.

I read through the posts on your forum and export/import pipeline is still a convoluted PITA with loss of data and other problems. Tweaking is still the norm and it should be the exception. One of the biggest issues, IMO, is that with 3DGS being a fairly complete authoring enviroment, having 3rd party tools that can work with it seamlessly would a tremendous plus.

Cheers and good luck!
