Hi Folks, In my experience with the programs and operating systems Bryce and Hexagon worked well in Windows XP 32bit, Windows 7 64 bit Pro and Ultimate. Now I am using Windows 10 Pro 64bit fully updated with no issues. (Windows 7 is still in the background) Windows 10 is a powershell if you installed it as an upgrade. The programs run fine, with the working screens in Bryce , Hexagon, importing, exporting and rendering in Bryce 7. Just save a lot and reboot before rendering. Running Large Address Aware from Tech PowerUp helps. Shut down applications you don't need, as long as you are not trying to work on a 950MB+ picture program, it can be taxing on Bryce as far as resources go. But as long as there are users of the programs I hope models will still be available on the web. I agree with the comment about the industry heading towards the 3D gaming engine. as we see so many new games out there. Unity 5 seems to be somewhat dominant. But we won't discuss Unity here this is NOT a gaming forum. Cheers everyone. (datadraw50).
