I rendered a movie last night and brought the C: hard drive to the lab to print it to tape and Vegas had to re-render it. I figured as much that the properties were pointed to C: for the render folder. When I took this drive out of the computer it became D: on the PTT machine. I tried to change the render folders to D: but it did not recognize them. How can I take my rendered material from/to the lab if the prerender has to be drive specific?
