Chế Độ Biên Soạn Hạt (Particle Edit Mode)
Using "Chế Độ Biên Soạn Hạt" you can edit the keyed points (keyframes) and paths of Tóc/Lông (Hair), Hạt (Particle), Vải Vóc (Cloth), and Thân Mềm (Soft Body) simulations. (You can also edit and style hair before baking.)
Since working in Particle Edit Mode is pretty easy and very similar to working with vertices in the 3D Viewport, we will show how to set up a particle system and then give a reference of the various functions.
Quan trọng
Particle Edit Mode, specifically for hair is deprecated; please use the new Tóc Trống Rỗng (Empty Hair) object with its associated Sculpt Mode instead.
Cách Sử Dụng (Usage)
Mẹo
Only Frames Baked to Memory are Editable!
If you cannot edit the particles, check that you are not baking to a Disk Cache.
Cấu Hình hệ thống Hạt cho Tóc (Setup for Hair Particles)
Create a Hair particle system.
Give it an initial velocity in the Normal direction.
Kiến tạo một địa ranh.
Check the "Động Lực Học của Tóc" box.
Editing hair strands in Particle Edit Mode.
Cấu Hình hệ thống Hạt, mô phỏng Vải Vóc và Thân Mềm (Setup for Particle, Cloth, and Soft Body Simulations)
Use Emitter particles, or a cloth/soft body simulation.
Create a simulation by setting up objects and or emitters, set your time range (use a small range if you are just starting out and experimenting), set up the simulation how you want it, using Alt-A to preview it.
Nướng mô phỏng (Bake the Simulation)
Once you are happy with the general simulation, bake the simulation from Object Mode. The simulation must be baked to enable editing.
Biên soạn mô phỏng (Edit the Simulation)
Switch to Particle Edit from the Mode select menu in the header of the 3D Viewport to edit the particle's paths/Keyframes. You may need to press T from within the 3D Viewport to see the Particle Edit panel. Move to the frame you want to edit and use the various Particle Edit tools to edit your simulation. Work slowly, previewing your changes with Alt-A, and save often so that you can go back to the previous version should something happen, or that you do not like the latest changes you have made.
Mẹo
To be able to clearly see what you are working on:
Open the Options panel in the Toolbar.
Select Point select mode (see below) in the header of the 3D Viewport. This will display key points along the particle path.
Lựa Chọn (Selecting)
Single: LMB.

Linked: Move the mouse over a keypoint and press L.
Lựa Chọn A.
Circle Select C.
Lasso Select Ctrl-Alt-LMB.

You may also use the Select Menu.
Mẹo
Selections
Selections are extremely useful for modifying only the particles that you want. Hover over a particle path and press L to link-select it, hover over the next and press L to add that path to the selection. To remove a path, hold Shift and press L. To Deselect all press A.
The method to select individual points is the same as in Edit Mode. RMB to select, Shift-RMB to add/remove a point from the selection.
Chọn Ngẫu Nhiên (Select Random)
Randomly selects particles.
- Phần Trăm (Percent)
Percent of particles to randomly select.
- Random Seed (Mầm Ngẫu Nhiên)
Seed value to use for the selection.
- Hành Động (Action)
Select random can be either used to select or deselect particles.
- Thể Loại (Type)
Selects either hair or points. Here these terms can be confusing because hair/point does not refer to the particle type but the path/points of the hair/particle.
Chế Độ Lựa Chọn (Select Modes)
Chế độ lựa chọn.
- Đường Đi/Dẫn (Path)
No keypoints are visible, you can select/deselect only all particles.
- Điểm (Point)
You see all of the keypoints.
- Đỉnh (Tip)
You can see and edit (including the brushes) only the tip of the particles, i.e. the last keypoint.

Chải bằng Lược (Comb)
Moves the keypoints (similar to the Proportional Editing tool).
- Làm Lệch Hướng Vật Phát (Deflect Emitter)
Hair particles only -- Do not move keypoints through the emitting mesh.
- Khoảng Cách (Distance)
The distance to keep from the Emitter.
Làm/Mịn Màng (Smooth)
Parallels visually adjacent segments.
Thêm (Add)
Adds new particles.
- Số Lượng (Count)
The number of new particles per step.
- Nội Suy (Interpolate)
Interpolate the shape of new hairs from existing ones.
- Số Phân/Bước (Steps)
Amount of brush steps.
- Các Phím/Số Điểm Điều Khiển (Keys)
Số lượng điểm điều khiển sử dụng để tạo các hạt mới.
Chiều Dài (Length)
Scales the segments, so it makes the hair longer with Grow or shorter with Shrink.
- Kéo Dài/Thu Ngắn/Phình ra/Thu Lại (Grow/Shrink)
Sets the brush to add the effect or reverse it.
Làm Bồng Lên (Puff)
Rotates the hair around its first keypoint (root). So it makes the hair stand up with Add or lay down with Sub.
- Thể Tích Làm Bồng Lên (Puff Volume)
Apply puff to unselected end points, (Helps to maintain the hair volume when puffing the root.)
Cắt (Cut)
Scales the segments until the last keypoint reaches the brush.
Trọng Lượng (Weight)
This is especially useful for soft body animations, because the weight defines the soft body Goal. A keypoint with a weight of 1 will not move at all, a keypoint with a weight of 0 subjects fully to soft body animation. This value is scaled by the Strength Min to Max range of soft body goals...
Tùy Chọn Chung (Common Options)
Below the brush types, their settings appear:
- Bán Kính (Radius) F
Đặt bán kính của đầu bút vẽ.
- Độ Đậm/Sức Mạnh/Cường Độ (Strength) Shift-F
Set the strength of the brush effect (not for Add brush).

Enable mirror editing across the local X axis.
- Bảo Tồn (Preserve)
- Chiều Dài Sợi (Strand Length)
Keep the length of the segments between the keypoints when combing or smoothing the hair. This is done by moving all the other keypoints.

Cắt Hạt thành Hình Dạng (Cut Particles to Shape)
- Đối Tượng Chỉnh Hình (Shape Object)
A mesh object which boundary is used by the Shape Cut tool.
- Cắt (Cut)
This grooming tool trims hairs to a shape defined by the Shape Object. This is a quicker way of avoiding protruding hair sections from lengthening than using the Cutting tool. It works especially well for characters with extensive fur, where working in a single plane with the Cutting tool becomes tedious.

Di Chuyển các Điểm Điều Khiển hoặc các Hạt (Moving Keypoints or Particles)
To move selected keypoints press G, or use one of the various other methods to move vertices.
To move a particle root you have to turn off Keep Root in the Toolbar.
You can do many of the things like with vertices, including scaling, rotating and removing (complete particles or single keys).
You may not duplicate or extrude keys or particles, but you can subdivide particles which adds new keypoints .
Alternatively you can re-key a particle .
How smoothly the hair and particle paths are displayed depends on the Path Steps setting in the Toolbar. Low settings produce blocky interpolation between points, while high settings produce a smooth curve.

Hiding and unhiding of particles works similar as with vertices in the 3D Viewport. Select one or more keypoints of the particle you want to hide and press H. The particle in fact does not vanish, only the key points.
Hidden particles (i.e. particles whose keypoints are hidden) do not react on the various brushes. But:
If you use Mirror Editing even particles with hidden keypoints may be moved, if their mirrored counterpart is moved.
To unhide all hidden particles press Alt-H.
