Skin tight pants nCloth sim, pants tearing, TOPOLOGY or nCloth Settings

#1

Hi everyone,
I have several questions relating to simulating skin-tight pants with nCloth. The pants were created in Marvelous Designer 7 and retopologized using zBrush and Maya 2017. A video of my runup and the first 10 frames is listed below. The model, rig and motion come from a maya sample mocap file. The working scale is centimeters and I adjusted the nCloth nucleus accordingly. My questions in ITALICS are listed below. The QUESTION SUMMARY sections just lists all my questions. The QUESTIONS section gives an explanation of what I am seeing and my question. Apologies for the length and any misstatements as I am a Maya beginner.

QUESTION SUMMARY
I am seeing tearing on the pants during the simulation. Is this a thickness issue? Can someone suggest the type of things I should be looking for in this setting because if i lower the thickness too far everything disappears or i see a lot of interpenetration?

QUESTION 3
i see weird tearing in the cloth during the simulation (PIC 10 & 11). At first I thought that this is just some kinda of viewport issue so I rendered the frame with Maya Hardware 2 and the artifacts are still there (PIC 12). My thickness settings for the body and cloth are (PIC 13 & 14). If I turn on thickness on the body I see PIC 15. If I turn on thickness on the pants, I see PIC 16. When I turn on both I see PIC 17

Are these artifacts the results of thickness settings (the cloth is pretty stretchy, stretch resistance = 10)? Can someone suggest the type of things I should be looking for in this setting because if i lower the thickness too far everything disappears or i see a lot of interpenetration?

PIC 15 (body thickness)

PIC 16 (pants thickness with small part of body coming through)

PIC 17 (body and pants thickness)

i wont sim that at all… just skin it and delete the legs under it… even wider cloth is often not simmed in some areas…

Hi oglu,

thanks for the tip. I am new to this. Can you please elaborate or maybe point to something I can read?

He’s saying that if you’re going for skin-tight leggings, run your simulation then hide the leg model parts beneath it instead. Much more efficient, and you won’t have to worry about these protrusions.

Unless you really need a few cloth-like wrinkles, you could just do leggings with texture maps.
