Yes, I use Tornado3D quite a lot. I bought v1.5 and upgraded to v3.0. It's very good rendering program, and gives excellent results. Sadly there are some bugs in v3.0, which leads to stability problems, but if you learn how to avoid them it works very good.
Rendering on PPC is very fast. Frames are rendered in the 10s-40s range even in high resolutions like 800x600. One of the best Amiga PPC programs ever made.
It would probably work nicely with AmigaOS v4. But a problem is that the hardware key uses the joystick port on the amiga so it can't be used on the AmigaOne or PegasOS :-(
Sadly I think Eyelight went bust. Too bad really since it's a great program.
