Non-cached Cached Motion Vector Map

Flame Flame Questions
1

I have a not infrequent issue where I cache motion vectors for a shot in action and they are… not actually cached. As in every time I move a couple of frames away it has to recalculate the motion vectors. I can see the motion vectors on the batch shelf, but it has missing frames and odd blank frames. I’ve tried deleting it and re-caching but it still flakes out after a bit. My terminal is filled with this:
action282 : Node “action282” is missing internal data
Action: Error rendering live preview.

Has anyone else run into this and have some sort of clever fix? It’s really slowing me down.

I would love to know how to not have this. It’s why I don’t use vectors as much as I would like.
@ALan ?

We always pre-render our Caches. Watch Ep2. of You’ve Been Sooth’d. But there are still several invalid-invalidation scenarios. I fully encourage you to report it to support.

For what it’s worth, I’ve gotten the in habit of caching MVs in a separate action completely disconnected from the rest of the comp. Once cached they appear in the batch group reels, I’ll grab a copy and use them where they’re needed.

Don’t know if it helps….

Unless I’m confused Ep.2 looks like it’s about Teridici, but I’d love to see what you’re doing there.

You’re right… it is Ep.2 of the Sooth’d series.

Haha, I just pulled up a fresh action, cached the vectors map, dropped it into my tracking action, hit F4….

screen record it and send to support.
