Cloth simulation problem

#1

Good morning. I am trying to recreate this effect in maya:

That was made with 3ds max, mcloth.

I was trying to use the volume axis field, but looks like the turbulence is kinda weird, i can not find the right values to get something like that.

I would really appreciate help with this.

Thanks.

Post an example of what you have otherwise its nearly impossible to just say “Here, use these settings”

#3

Your are right.

i think i have some scale problem. I am not sure, i had tried different settings.

Thanks

Yes, you either have too much dampening or not enough magnitude in your fields, or several other variables that may be affecting it. You could first try to lower your Space Scale in the Nucleus.

Post a scene file if you can.

Don’t use a turbulence field. Use the nucleus wind, along with a little wind noise. The substeps should and stretch resistance should be fairly high. Don’t use any input attract or rigidity( it looks like you have a lot in that sim ). Also with bend resistance you can use some bendAngleDropoff (around 0.5) so that there is little bend resistance for small bend angles, allowing small ripples.
With the nucleus wind, lift, drag and tangential drag zero or near zero the ripples will naturally form with no turbulence required.

Thanks duncan, i will try that. I really appreciate your help.

Cheers.

Hi Duncan. I tried what you said, and it looks great i think, please check this video:

But, when I activated the geometry cache in the character and it starts moving, this happens:

capture

right now my substeps are 16 and the max collision iterations are 23.

The character size is about 154 maya units, and i am working in cm. Also, i set up the space scale to 0.010.

Thanks, i really appreciate your help.

Check the collision mesh… does it have any places where there is self interpenetration that could affect the cloth(like a hand going through a leg). Normally the trap check on the nRigid can handle cases where a single sheet of cloth gets trapped by interpenetration of the rigid, however it can be more problematic when there are two or more thickness of cloth involved… like where an elbow might penetrate the body. In such cases selfTrappedCheck on the cloth can help…this keeps cloth from exploding when it self interpenetrates, and keeps it from sticking together when it has intepenetration failure… although in some cases it can allow for more self collision failure. Another thing that can help is to lower the collision strength, especially if the collision thickness is high( this is basically the repulsive force when collisions are within the collide thickness).

As well there have been some problems with trap check not working in some releases… it might help if you have the latest 2014 cut.
