Little tutorial for fake Collision on a dress/skirt

Here's a little tutorial about the way I create a fake collision on the skirt based on Urbosa's dress : https://www.artstation.com/artwork/6LVg65

Setup: Main controller at skirt edge (world pivot) → parentConstraint to "inf" group with Pelvis/FLY/WORLD → driven keys for Follow attribute = space-switching system

PLAN group positioned at pelvis location
OFFSET group positioned at controller location
Scale attributes connected directly to PLAN group (handles both FK/IK spine controllers)

This ensures consistent scaling behavior regardless of spine control method.

AIM Setup (Order Critical):

aimConstraint on AIM group → target trans_aiming_skirt
Parent OFFSET under AIM → zero rotations
Re-parent AIM under OFFSET → zero AIM values

This parenting sequence ensures clean zero values while maintaining proper constrain

Demonstration of the rigging skirt

Fake collision system: pointConstraint to knee (no offset), angleBetween node from locators, euler drives target joint + orientConstraint

Compares L/R orient rotations through NotEqual + LessThan condition nodes. Output drives middle orient group for auto collision

Pre-animation buttons via c_skirt_master:
Sway: multDoubleLinear, input2=-1 (reverse Z rotation)
Puff: Same as Sway but on X rotation
Ripple: drivenKeys on X, cycle curve, connections for amplitude control
