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 最小化拉伸 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.
工具设置
笔刷
- 笔刷
在 数据块菜单 中选择预设笔刷类型或自定义笔刷。
笔刷设置
- 半径
该选项控制笔刷的半径，以像素为单位。F 允许你通过拖动鼠标和 鼠标左键 交互式地改变笔刷大小。在使用 F 时输入一个数字然后回车可以让你更改数字大小。
- 压感区大小
Brush size can be affected by enabling the pressure sensitivity icon, if you are using a Graphics Tablet.
- 使用统一半径
在所有笔刷上使用相同的画笔 半径。
- 强度
控制笔刷的每次应用对 UV 的影响程度。你可以通过在 3D 视窗中按下 Shift-F，然后移动笔刷，再按下 鼠标左键，来交互地改变笔刷的强度。你也可以在 Shift-F 调整尺寸时输入数字。
- 使用统一力度
所有笔刷使用相同的笔刷 强度。
- 松弛方法
There are three ways to determine the edge weighting:
- 拉普拉斯:
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".
- 几何数据:
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.
Note
All brushes use the Airbrush Stroke Method; they continue to act as long as you keep LMB pressed.
衰减
The Falloff allows you to control the Strength falloff of the brush. See Painting Falloff for more information.
