Hi, got TS for xmas and have a couple of questions. I've heard of a SV version. The order form isn't clear on how much it costs and tells me nothing about why I would want it. I remember reading something about it having more textures, anything else? Also, will the FP version work with a CMI Processor Accellerator? (The one with a 16mhz 68000 and a 68881) Great program, I'm already saying Sculpt who? Bill
