There was a stand alone version of Lightwave sold at one time, but the version you have on the 4.3 CD requires a VT or dongle to operate. You can pick up VT cards fairly cheaply these days compared to what they were selling for a few years ago. Everyone doing video is moving to digital, so most VT users are selling theirs now and it is dragging the prices down fairly quickly. I think even the original A2000 VT will work as a dongle to run Lightwave, but have not confirmed this.
P.S. See you on the 20th for our drive up to AmiWest. If anyone else is interested in joining us, send me a PMail.
