What is the best way to render a series of .TGA files to a Sanyo GVRS-950 through a Targa+64? (Without buying a PAR replacement) I've had problems (also noted in 3DS docs) rendering directly to tape with my TARGA+64 because of the dual frame buffers. The docs state that I should use a utility to send the sequential Targa files from DOS rather than directly from 3D Studio. I've contacted BCD, Sanyo, Truevision, with no useful results. Any advice, please????? Otherwise, anyone interested in a GVRS-950 with less than 100 hours on the heads (mostly as a record deck)???
