I get a weird error when trying to put text over an opengl sequence. The only frame that won't work is the last one. It doesn't depend on the frame numbers because I've tried doing it on multiple frame ranges, with the same result. The error from the log is this:
22:04:20.072: Setting batch sub index to 39
22:04:20.090: PDG_START: overlaytext1_ropfetch1_490;39
ERROR: The attempted operation failed.
Error: Cook error in input: over1.
Sometimes it does it on only 1 wedge, sometimes on all, sometimes it works. It seems to have no reason to exist, any fix?
