Toon only exports properly when split in two

I have a 15 minute cartoon. When I export it whole, I get “unable to load image file moon.tga” about 80% through. Throughout the reminaing 20% of the export, I get this message a dozen more times and the image names change. Sure enough when I play the movie those images are missing. If I export it as two 7.5 minute movies, everything works as it should. I get the same result with .mov or .avi using different quality levels. Currently running TB4. Thanks, Aaron

You might be running low on memory during the export process. You can try to free up RAM by closing other applications or background processes.
