Cloth Sim not working correctly at small scale

borbus

Hello guys,

i started rigging my character and i want to animate his hair through a cloth sim. But i noticed that the cloth sim doesnt really work correctly when used at a really small scale, it sort of jiggles.

A video showing off the differences in scale:

Is there any way to fix this? I tried appling scale and it doesnt do anything to change it. The only solution i see is to just use cloth sim only on larger scales, which would mean i have to rescale the character, which in turn would cause problems when exporting to unity/ue5 i believe.

Thank you in advance.

What scale is your character, and what units are you using?

Every game engine has a method to scale a character on import. This is viable as long as you keep it consistent.

Unit Scale is 1.0000 and uses the metric system.
The scale of my character is X: 1 Y: 1 Z: 1, because i had applied scale sometime ago.
and dimensions are X: 1,17m  Y: 0.288m Z: 0.91m
But these are just the values of the torso of my character, because the character consists of many different meshes

So, i just started using the wiggle bones addon for animating the hair, works like a charm!

Sounds like you already have a solution. But if your character is scaled to 1% (am I reading that correctly?) then that’s going to wreak havoc with any simulation system. Freeze those transforms!

I fact in blender for cloth simualtions it is better to scale up the object.. lager than life.. after you are satiesfied and baked the sim.. you can/have to scale it down again..
