An animated cube with its motion path displayed.¶
The Motion Paths tool allows you to visualize the motion of points as paths over a series of frames. These points can be object origins and bone joints.
To create or remove motion paths, it is necessary to first select the bones. Then:
To show the paths (or update them, if needed), click on the Calculate Path button.
To hide the paths, click on the Clear Paths button.
Ghi chú
Remember that only selected bones and their paths are affected by these actions!
The paths are shown in red for the section in the past and green for the section in the future. These colors follow the user preference options "Before Current Frame" and "After Current Frame", which can be found in the 3D Viewport section. Each frame is displayed by a small dot on the paths.
The paths are automatically updated when you edit your poses/keyframes, and they are also active during animation playback. Playing the animation affects the paths only when using the Around Frame type.
Các Tùy Chọn (Options)¶
The Motion Paths panel in the Armature tab.¶
- Loại Đường Chuyển Động (Paths Type)
Loại phạm vi để hiển thị các Đường Chuyển Động.
- Quanh Khung Phim (Around Frame):
Display paths of points within a fixed number of frames around the current frame. When you enable this button, you get paths for a given number of frames before and after the current one
- Trong Phạm Vi (In Range):
Display paths of points within specified range.
- Phạm Vi Tính Toán (Calculation Range)
The range of the motion path. Only active when "Loại Đường Chuyển Động" is set to "Trong Phạm Vi". Changing this option only takes effect when updating the path, via the "Cập Nhật Đường Dẫn" or "Cập Nhật Toàn Bộ các Đường Dẫn" buttons.
- Toàn Bộ các Khung Khóa (All Keys):
Generate a motion path ranging from the first keyframe to the last. Only the keys of the active object / bone are considered.
- Các Khung Khóa được Chọn (Selected Keys):
Same as All Keys except that it ranges from the first to the last selected keyframe.
- Phạm Vi Khung Hình của Cảnh (Scene Frame Range):
Use the start & end frames of the scene, or the preview range if active.
- Đặt Phạm Vi Thủ Công (Manual Range):
Đặt khung bắt đầu và kết thúc một cách thủ công.
- Phạm Vị Khung Hình Khởi Đầu, Kết Thúc (Frame Range Start, End)
Starting and Ending frame of range of paths to display/calculate (not for the Around Frame type).
Although the start and end frame are always editable, updating the motion path will change these according to the Calculation Range setting. To ensure your chosen frame range is maintained, choose Manual Range there.
- Phạm Vị Khung Hình Trước, Sau (Frame Range Before, After)
Number of frames to show before and after the current frame (only for the Around Frame type).
- Bước (Step)
Allows displaying one point for every n frames on the path. Mostly useful when you enable the frame number display (see below), to avoid cluttering the 3D Viewport.
- Bake to Active Camera
When enabled the motion path is calculated in screen space for the active scene camera. Note that the resulting motion path will only be useful for that single camera. Switching cameras using markers is not supported. It will only bake to the camera that is active when the bake was started.
- Bộ Đệm Nhớ/từ, tới Bộ Đệm Nhớ Xương (Cache/Bone Cache From, To)
These are the start/end frames of the range in which motion paths are shown. You cannot modify this range without deleting the motion path first.
- Tính Toán (Calculate)
If no paths have been calculated, Calculate Paths will create a new motion path in cache based on the options specified in the pop-up menu or the Điều Chỉnh Thao Tác Trước Đây (Adjust Last Operation) panel. Note, if the current context is an Armature calculating the objects motion paths, and not the bones, this operator will calculate the motion paths for all the bones within the armature as well.
- Khởi Đầu, Kết Thúc (Start, End)
These are the start/end frames of the range in which motion paths are shown. The start frame is inclusive, so if you set Start to 1, you will really see the frame 1 as starting point of the paths...
- Vị Trí Nướng (Bake Location)
Which point on the bones is used when calculating paths. Only available for bones while in Pose Mode.
- Đầu (Heads):
Calculates the path position of the bone's heads.
- Đuôi (Tails):
Calculates the path position of the bone's heads.
- Cập Nhật Đường Chuyển Động (Update Paths)
In the case a path has already been calculated, this operator will update the path shape to the current animation. To change the frame range of the calculated path, you need to delete the path and calculate it again.
- (Clear Paths)
Clears paths on all objects/bones or just the selected ones when holding Shift.
- Cập Nhật Toàn Bộ các Đường Dẫn (Update All Paths)
Recalculates the motion paths for all visible objects and poses.
Hiển Thị (Display)¶
- Số Khung Hình (Frame Numbers)
When enabled, a small number appears next to each frame dot on the path, which is of course the number of the corresponding frame.
- Các/Số/Khung Khóa (Keyframes)
When enabled, big yellow square dots are displayed on motion paths, showing the keyframes of their bones (i.e. only the paths of keyed bones at a given frame get a yellow dot at this frame).
- + Khung Khóa chưa Nhóm (+ Non-Grouped Keyframes)
For bone motion paths, it searches the whole Action for keyframes instead of in groups with matching name only (this is slower).
- Số Khung Khóa (Keyframe Numbers)
When enabled, you will see the numbers of the displayed keyframes, so this option is obviously only valid when Show Keys is enabled.
- Số/các Đường/Dòng (Lines)
Toggles whether the lines between the points are shown.
- Độ Dày (Thickness)
Độ dày nét cho đường chuyển động.
- Màu Tùy Chọn (Custom Color)
Use custom color for this motion path. The custom color can be modified for time before and after the current frame.
