But if the animators could just play once, then have all transforms cached until they are dirtied, well, that would be really nice. Ideally the caching would be almost completely transparent to the animator, that is caching would be no slower that playing the scene (which rules out file I/O). The "caching" attribute that exists on every node in Maya, that seems to exist for this purpose, doesn't seem to be implemented. I don't see any change in speed or memory when everything has this enabled. Maybe am I doing this wrong?
If I was going to do this, I'm thinking maybe a custom transform node that repects the caching attribute. Is this built in already and I'm just spinning my wheels? Or has anyone that's done anything like this have any words of advice?
It's a decent chunk of work and I know people have done this before, so I thought it would be worth a post.
