Toolbar ‣ Relax

The Relax brush can be used to distribute UVs more evenly. It works by pulling vertices along UV edges to bring the UV unwrap into balance.

The Relax brush can be compared with the Minimize Stretch tool which works directly on faces to reduce texture stretching and shearing. You may find that sometimes minimize stretch works better, sometimes the unwrap tool and other times the relax brush.

First using Unwrap, then Minimize Stretch and touching up with the Relax Brush often gives the best results. Remember, you can use «Undo» at any time to return to an earlier state.

The Меню блока данных to select a preset brush type or a custom brush.

Радиус

This option controls the radius of the brush, measured in pixels. F allows you to change the brush size interactively by dragging the mouse and then LMB. Typing a number then enter while using F allows you to enter the size numerically.

Размер нажатием

На размер кисти можно повлиять, включив значок чувствительности к нажатию, если вы используете графический планшет.

Использовать единый радиус

Использовать один и тот же радиус кисти для всех кистей.

Сила

Controls how much each application of the brush affects the UVs. You can change the brush strength interactively by pressing Shift-F in the 3D Viewport and then moving the brush and then LMB. You can enter the size numerically also while in Shift-F sizing.

Использовать единую силу

Используйте одну и ту же силу кисти для всех кистей.

Relaxation Method

There are three ways to determine the edge weighting:

Laplacian:

The classic discrete laplace operator applied to the UV graph. Each edge has equal weighting, resulting in triangles which resemble a honeycomb shape, or quads aligned into square grid.

HC:

Similar to Laplacian, the HC method uses equal weighting while trying to preserve a gradient between dense regions of the mesh and regions with fewer edges.e

Note, this method uses the «Humphrey’s Classes» operator as described in the paper: «Improved Laplacian Smoothing of Noisy Surface Meshes».

Геометрия:

Edges are weighted according to the discrete laplace operator (cotangent formula) applied to the 3D geometry. This tries to bring the relative lengths of edges in UV closer to the relative lengths of edges in 3D, resulting in a UV unwrap with less distortion across edge boundaries.

Примечание

All brushes use the Airbrush Stroke Method; they continue to act as long as you keep LMB pressed.

Спад#

The Falloff allows you to control the Strength falloff of the brush. See Painting Falloff for more information.
