I have noticed very little difference between version 6.5 and version 7. Version 7 does seem slightly faster, but the quality was better in version 6.5. I have always had a problem with graininess in my renderings and that seems quite a bit worse in version 7. On the plus side, I have had several issues with billboards in versions 6 and 6.5 and that seems to have been fixed in version 7. Finally, part of the reason we upgraded to version 7 was the advertised option to use Twinlinker. This sounds like it could be useful but there is NO help or instructions for how to use it. I have tried multiple things to bring in a file from Artlantis, but nothing seems to work. Any suggestions would be much appreciated.
