Memory Problems, Avoiding Blank Frames

Q When QuickTime VR doesn't have enough memory, it returns blank frames, but it doesn't tell us it's failing. Isn't QuickTime VR supposed to return an error message when there's insufficient RAM available for a QuickTime VR scene to be displayed?

The only way we can avoid the blank frames is to scale the system (System 7.5 on a PowerMac 7100-66 with 16MB) down to 5.5MB of system memory, 6MB for Director, and the remainder for QuickTime VR

A The most important factor regarding run-time memory requirements is the size of the source image. If you're not using dual-resolution files, and your source images are 768 x [something], you'll need approximately 4MB of RAM at run-time. Dropping to 384 x [something] images reduces the memory requirements to approximately 1MB at run-time.
