Overview

Physical Properties is a function for applying physical properties to the surface to grant physical features similar to the actual fabric.

Location

Surface > UI Panel > Fabric > Physical Properties

Operation Method

1. Select the surface to change the material properties.
2. Adjust the value to change via UI Panel > Fabric > Advanced Physical Properties.
3. Check whether the desired physical properties are obtained when running the simulation.

Components

physic preset

Physic Preset contains the default physical properties of fabrics.

weft/warp

This option is for adjusting the weft and warp values of physical properties.

When the checkbox is ticked, the weft and warp values can be adjusted separately. When the checkbox is empty, the weft and warp values are adjusted at the same time. You can change the weft and warp directions by using the fabric placer.

(Weft: horizontal direction of fabric; Warp: vertical direction of fabric)

Weight

Weight is equal to mass per unit volume (m²).

A higher weight means the surface has heavy properties, which causes it to sag down and is affected less by wind.

On the other hand, a lower weight means the surface has lighter properties, which causes it to sag less and is more affected by the wind.

stretch

Stretch shows the stretch level of the surface affected by the surrounding environment.

The higher the value, the less stretch it has; the lower the value, the more stretch it has.

shear

Shear shows the stretch level of the surface affected by the surrounding environment in a diagonal (bias) direction.

The higher the value, the less stretch it has; the lower the value, the more stretch it has.

bend

Bend shows the bend level of the surface affected by the surrounding environment.

The higher the value, the less it bends which maintains a flat form; the lower the value, the more it bends which makes soft drape possible.

Thickness

Thickness shows the thickness of the surface shown in 3D view.
The higher the thickness value, the thicker it appears; the lower it is, the thinner it appears.
It can be checked before simulation or during a paused simulation, but Thickness must be activated via the 3D menu.

Collision Thickness

Collision thickness shows the surface thickness in the simulation, not the visual thickness.

The higher the collision thickness value, the more space there is between fabrics or avatars. The lower the value, the more space there is between the fabrics or avatars.
