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
该选项控制画笔的半径，以像素为单位。F 允许你通过拖动鼠标和 LMB 交互式地改变画笔大小。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。
- Size Pressure
Brush size can be affected by enabling the pressure sensitivity icon, if you are using a Graphics Tablet.
- Use Unified Radius
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，然后移动画笔，再按下 LMB，来交互地改变画笔的强度。你也可以在 Shift-F 调整尺寸时输入数字。
- Use Unified Strength
所有笔刷使用相同的笔刷 强度。
- Relaxation Method
有三种方法来确定边缘加权：
- 拉普拉斯
经典的不连续拉普拉斯算子应用于UV图。每条边都有相等的权重，从而产生类似蜂窝状的三角形，或排列成方形网格的四边形。
- HC
与拉普拉斯类似，HC方法使用等权，同时试图保留网格密集区域和边缘较少区域之间的梯度
Note, this method uses the The "Humphrey's Classes" operator as described in the paper: "Improved Laplacian Smoothing of Noisy Surface Meshes".
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.
