Hello, I have less than 2000 points (they're even cached and loading from disk!) but viewport playback is incredibly slow. The cache file is tiny at only 8mb.
These points have an instancefile sequence attribute playing through a proxy file sequence. Nothing else.
I have tried playback on a faster PC, and it does go faster, but on my main work PC this node playback is painfully slow.
What could be causing this to play down so slowly?
The performance monitor shows only one thing taking time:
Seems houdini is trying to load those instancefiles and slowing it down, even if in my case it can't get to those files at all. If you delete that attribute it scrubs much faster.
The points don't appear to be moving at all, so if you put down a timeshift and lock it to frame 1, it scrubs faster still.
Hi mestela, you could right. I think I am just trying to load far too many different proxy files all at the same time and the proxy frame offset is causing it to search and load again on every framestep.
I will need to look into a different way of instancing these objects onto points.
I did try the instancefile method which was wonderously fast, but I could never get the randomised timeframe offset working with a looping sequence.
