[Blender 2.83α] How to use the Cloth Brush

This article outlines how to create wrinkles in fabric using the Cloth Brush, which is implemented in Blender 2.83 Alpha.

What is Cloth Brush?

Cloth Brush is a sculpting brush that will be implemented in Blender 2.83. It can transform a mesh into a cloth-like texture.

The Alpha version of Blender 2.83 is now available and can be downloaded from

https://builder.blender.org/download/

Basic Usage

First, prepare the mesh you want to transform (flat in this case) and add a subdivision surface modifier to make the vertices as fine as possible.

Divide it into smaller pieces.

Switch to object mode and “apply” a modifier.

Switch to sculpting mode from the Sculpting tab at the top of the screen.

The brushes are lined up on the left side—select “Cloth” from these options.

Cross brushes

If you hover the cursor over the mesh with a “Cloth” brush selected, you will see multiple circles.

These values can be changed from “Tools” in the Properties panel that appears when you press the N key.

  • Radius: specified in px number
  • Strength: specified by the ratio of the radius to 1
  • Simulation Limit: specified as a ratio of the radius to 1
  • Simulation Falloff: ratio of the Simulation Limit to 1 and the radius to 0

Let’s drag it over the mesh, and you will see that it moves like cloth.

Experiment with different cloth representations

Let’s explore some of the ways you can use these brushes with the help of a video tweet from Pablo Dobarro, the developer of Cloth Brush.

When working, divide the mesh of the object to be deformed into smaller pieces so that it is as even as possible.

Use a loop cut to divide it vertically as well.

By default, it is set to transform symmetrically, but you can also remove it from the “Symmetry” section.

The values of each parameter are shown in the video, but the effect varies depending on the object’s shape and size, so please try it for reference only.

Pinch the cloth – Pinch Point (Radiant)

If you change the Transformation to Pinch Point and set the Farce Falloff (Force Attenuation) to Radiate underneath it, you will get a pinching effect on the fabric.

Wrinkles – Pinch Point (flat surface)

If you change the Transformation to Pinch Point and set the Farce Falloff (Force Attenuation) to Flat underneath it, you can deform the crease of the sleeve, as just one example.

Inflate (radiate)

If you change the Transformation to Inflate and set the Farce Falloff (Force Attenuation) to Radiate underneath it, you will get a deformed look as if the fabric has been inflated with air.

Upload to STYLY

You can then upload your deformed objects to STYLY.
