Scale is an elastic deformation tool.
Holding Ctrl will invert the Scale effect to the vertices.
There are several options that affect how Scale Tool works.
| Option | Description |
|---|---|
| Stiffness | How much the mesh resists shear |
| Incompressiblity | How compressible the spatial region is: 1 - 2 x Poisson ratio |
| IntegrationTime | Integration Time for elasticity |
| BrushSteps | Integration steps |
