View Full Version : Fluid nCache Limitations

Have any of you noticed a fluid nCache size limitation? Is there a way around this?

Today I tried to cache a fluid container and It crashed maya every single time I hit the button. It would play through fine in the viewport. I had to lower the resolution by 50% to get a cache but that caused a massive loss of detailed swirls.

Couldn't Cache:
3d Fluid Container
Scale 5,5,5
Scale 10,14,10
Res 120,168,120
Cache File per Frame
Maya 2009 x64
core i7 with 12gb ram
ntfs partition

Also attempted on Dual Quad Mac and same i7 machine booted on linux with x64maya and ext4 partition.

OMG that seems not supposed to happen in this situation, have you tried rebuild a similar setup in a new scene? or have you tried to put the transform node's scale back to 1? i think the transform node for fluid is better not having any scale...

Just to confirm, you're on 2009 SP1a? I'm running x64 and service pack 1a on an i7 and it's solid.

ovspianist - I saved the container as a preset and applied it to a new container and still the same issue. I also tried changing the default maya unit to feet. I will see if by odd chance that it works at scale 1. If so then I can scale it back up after I cache. The reason it is scaled up is that maya seems to calculate faster that way than to use the size attribute. I don't usually let the size attr get above 15-20

YourDaftPunk - Yes I am running SP1 downloaded straight from autodesk. Can you confirm that a fluid container of these attributes will create a nCache?

...wired david said so too(the funny destruct007 david~!). but in my experience when i turn the scale of the transform up to 100 or somthing like that, the simulation goes slow like hell... i don't know why, my sim still goes fast even if i have a 1000*1000*1000 size grid.

i'm using maya 8.5 at work, 2009 at home, both the same result.
