UV Brush surface tool

The UVBrush operation allows you to interactively manipulate the texture coordinates of your geometry.

The UVBrush operation allows you to interactively manipulate the texture coordinates of your geometry.

As you move the mouse over the geometry, in the UV viewport you will see a circular brush follow the surface to show where you would paint. The size of this brush and its orientation will show you which points will be affected by a brush operation.

Like all the brush tools, you have two different brushes: your Foreground brush and your Background brush. You brush with your foreground brush using the LMB and the background with the . The dilation factor is controlled by the FS and BS parameters respectively.

Each of the brushes also can have its own independent operation. To select the operation for each brush, Ctrl + to bring up the operation menu. The options are:

• Drag: This drags the uv textures in the direction of the brush stroke.

• Dilate/Contract: This uses the dilation factor (either FS or BS) to enlarge or reduce the area under the brush. UV Textures are moved away or towards the center of the brush.

• Smooth: This smoothly blends the textures coordinates. Boundary points are left unchanged.

• Erase Changes: Thus is a local undo - it restores the positions under your brush to the pre-uvbrush values.

The other main parameters are:

• Radius: The size of the brush.

• Opacity: How strong the brush is. A fully opaque brush replaces the original positions, while a less opaque brush blends it.

The other Ctrl + menu options are:

• Circle/Square/Bitmap Brush: The shape of the brush. The bitmap is set in the operation parameters dialog.

• Orient Brush To Surface: When disabled, the brush is always oriented the same way. This is useful when painting crinkly geometry.
