Suy Giảm Dần [Falloff]¶
The Falloff is a curve that determines how the strength of the brush decreases with increasing distance from the center. You can set up a custom curve or choose a predefined one.
Brush falloff example.¶
- Sắp Đặt Sẵn của Đường Cong (Curve Preset)
- Tùy Chỉnh (Custom)
Shows a Thành Tố Điều Khiển Đường Cong (Curve Widget) for configuring a custom falloff. The left side of the curve corresponds to the center of the brush while the right side corresponds to the edge.
- Predefined
The predefined falloff curves look as follows:
- Hình Dạng của Suy Giảm Dần (Falloff Shape)
Determines how the falloff distance is calculated.
- Hình Cầu (Sphere):
The falloff is calculated using a sphere in three-dimensional world space. If two points on the mesh appear near each other in the 3D Viewport but are far away in the world, painting one will not affect the other.
- Dự Phóng (Projected):
The falloff is calculated using a circle in two-dimensional screen space. If two points on the mesh appear near each other in the 3D Viewport, painting one will also affect the other, no matter their distance in the world.
Texture Paint Mode does not have this option -- it always uses Projected.
- Normal Falloff / Front-Face Falloff
Weakens the brush strength for faces whose normal points towards the screen edges instead of the camera.
This feature is not available in Sculpt Mode.
- Góc Độ (Angle)
The minimum angle between the face normal and the viewing direction for the falloff to start.
