View Full Version : Single Cache or Multiple Cache

I have a project that I am working which has all the animation finished and now needs some nCloth on one of the characters capes. I am a novice when it comes to nCloth and my experience is limited to watching the Digital Tutors Intro to nCloth as my training.

In my scene it all takes place on the bridge of a ship and amounts to about 5100 frames. Originally, in my experiments I made caches wherever the character appeared, recreating the initial state for the cloth and then running the simulation 50 or so frames in advance to let the cloth settle before caching. It has mixed results…

Now I am wondering whether I should just do one big cache through the whole scene and then go back a tweak bits afterwards.

Have a look at this link (http://www.gazzamataz.com/King_Cloth_Cape.mov) which is the opening sequence.

Hey Gary,

That looks like a pretty cool project.
What I would do first is break that scene down in to shots. I would then cache the cloth on a per shot basis. Caching 1500 frames as one cache file is not something I would recommend doing. If Maya were to crash at frame 1499.... wouldn't be such a fun thing. If you insist on caching it as a scene, then I would set it to 1 cache per frame... but again, I wouldn't go that route personally.

Good Luck!

Hey Wick3dParticle

Thanks for the reply. I guess I'll stick with doing it a shot by shot basis, cos every time I try to do a playblast from frame 1180 to 6546 Maya crashes anyway.

Thing is some of the bits don't mix well so I think I might have to get me paint brush out.

If I am not mistaken I think there is a 2 GB limit to single cache files in Maya. Maybe your running into that.

Definitely break it up into separate shots as suggested. Also, try the per frame cache option if you want. It sometimes helps during a network render as I've noticed maya really crawls sometimes while reading big cache file even over a good network, be it fluids, particles or ncloth or animation point cache.

I have been able to cache 6GB files before. But i would recommend WickedParticles way of doing it.

OK I am progressing with this project but it is very slow on my old banger PC…

I have reasonable looking cloth now but I have this bouncing problem appearing on the collar area. Click on this link (http://www.gazzamataz.com/King_Collar.mov) to have a look.

I am not sure how to fix this. Would increasing the nucleus substeps and set max collision iterations help?

I have tried keyframing the friction settings from 0.8 to 0 but it still bounces. It is obviously something to do with the cloth colliding with the collar plates.

Any help greatly appreciated…
