Cloth simulations

Overview

The cloth solver simulates how flexible sheets bend, fold, compress and stretch, and so on.

See relationships for how to make cloth interact with other objects.

The Cloth shelf tab contains tools for creating and stitching cloth sheets. You can also use the forces on the Drive simulation shelf tab to affect the cloth.

The Cloth Constraint tool lets you pin a point on a cloth object to a point in space or another object.

The Cloth Stitch Constraint tool lets you stitch together a set of points on one surface to a set of points on another surface.

Bend strength	Increase this to make the cloth smoother/more resistant to wrinkles.
Maximum compression	A number between 0 and 1, describes how much force you must apply to the cloth before it begins stretching.
Stretch strength	The resistance to stretching. Higher numbers mean the cloth is harder to stretch.
Shear	Resistance to shearing (forces along the plane of the cloth; if you stretched a square into a parallelogram that force would be shearing). This affects creasing where cloth is draped over a corner, as in a tablecloth on a table.
Bend damping	Resistance to bending. Higher values make the cloth slower to bend.
Curl	Curl causes the cloth to try to roll up in both directions. If you set Curl to 45 and animate, the cloth will curl up at the corners to 45 degrees.
Inflate	Inflate is an absolute scaling factor on the size of the cloth. If you animate this value to increase over time you can simulate things like an inflating balloon. Do not instantly set the value of this parameter to a number greater than 1; you need to increase it over time.
