Mike, If you arrange in your ‘append’ overload to always return the same Hash value, the caching system won’t save the frames because it won’t detect they are different. The problem is, I’m pretty sure the Viewer won’t know to update its image window as well. Very fast, but perhaps not too useful.

Hi there, I am working on an image sequence generator which produces image data around 20 fps on my machine when I have turned off Viewer Cache (Disk cache) manually at the preferences panel. If the Viewer cache is ON, the caching has actually slowed down the playback, I guess the procedurally generated data is kinda faster than cached playback in this case (My cache disk is slow anyway). In addition, the cache system allocates additional memory which quickly hit the peak memory (as i was changing my params interactively) and the memory manger kicks in and caused additional slow-down. So I would like to know if there is any means that may instruct Nuke not to generate Viewer cache of my output. (at least allow my users to choose). I have tried "asapUpdate()" as I saw from the documentation that it will disable Viewer cache but it didn't work. Any idea or pointers?
