I added the sixcube process via pdtoots to a video. Looked great in preview, but ever time I tried to view the video is have to render those section, not a big deal. However if I can to make an MPG4 video from it PD errors out whenever it reaches the text effect with the message "can't generate cache file." If I take those out the video generates fine.
What is this message telling me and how to I get around the problem. I really like this effect and want to you it more.
