Modo Editar Partículas
Using Particle Edit Mode you can edit the keyed points (keyframes) and paths of Baked Hair, Particle, Cloth, and 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.

Truco
Only Frames Baked to Memory are Editable!
If you cannot edit the particles, check that you are not baking to a Disk Cache.

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.
Captura de la simulación
Once you are happy with the general simulation, bake the simulation from Object Mode. The simulation must be baked to enable editing.
Edición de la simulación
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.
Truco
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.
Selección
Single: LMB.
Todo: A.
Linked: Move the mouse over a keypoint and press L.
Marco de selección B.
Selección de Círculo C.
Lazo de Selección Ctrl-Alt-LMB.
Root/Tips: .
You may also use the Select Menu.
Truco
Selecciones
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.
Seleccionar aleatoriamente
Randomly selects particles.
- Porcentaje
Percent of particles to randomly select.
- Semilla de aleatoriedad
Seed value to use for the selection.
- Acción
Select random can be either used to select or deselect particles.
- Tipo
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.
Modos de selección
Los modos de selección.
- Ruta
No keypoints are visible, you can select/deselect only all particles.
- Punto (o Apuntar)
You see all of the keypoints.
- Diámetro Punta
You can see and edit (including the brushes) only the tip of the particles, i.e. the last keypoint.

- Herramienta
Peinar
Moves the keypoints (similar to the Proportional Editing tool).
- Deflectar emisor
Hair particles only – Do not move keypoints through the emitting mesh.
- Distancia
The distance to keep from the Emitter.
Suavizado
Parallels visually adjacent segments.
Agregar
Adds new particles.
- Cantidad
The number of new particles per step.
- Interpolar
Interpolate the shape of new hairs from existing ones.
- Intervalos
Amount of brush steps.
- Teclas
How many keys to make new particles with.
Longitud
Scales the segments, so it makes the hair longer with Grow or shorter with Shrink.
- Crecer / Contraer
Sets the brush to add the effect or reverse it.
Soplar
Rotates the hair around its first keypoint (root). So it makes the hair stand up with Add or lay down with Sub.
- Volumen soplado
Apply puff to unselected end points, (Helps to maintain the hair volume when puffing the root.)
Cortar
Scales the segments until the last keypoint reaches the brush.
Influencia
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…
Opciones en común
Below the brush types, their settings appear:
- Radius F
Set the radius of the brush.
- Intensidad Mayús-F
Set the strength of the brush effect (not for Add brush).

- Auto-Velocity Emitter
Recalculate velocities of particles according to their edited paths. Otherwise, the original velocities values remains unchanged regardless of the actual distance that the particles moves.
- Simetría en X
Enable mirror editing across the local X axis.
- Preservar
- 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.
- Root Positions
Keep first key unmodified, so you cannot transplant hair.
Cut Particles to Shape
- Shape Object
A mesh object which boundary is used by the Shape Cut tool.
- Cortar
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.

- Path Steps
The number of steps used to draw the path; improves the smoothness of the particle path.
- Children Hair
Displays the children of the particles too. This allows to fine-tune the particles and see their effects on the result, but it may slow down your system if you have many children.
- Particles Emitter
Displays the actual particles on top of the paths.
- Fade Time
Fade out paths and keys further away from current time.
- Fotogramas
How many frames to fade.

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 rekey 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.

It may happen that after mirroring two particles occupy nearly the same place. Since this would be a waste of memory and render time, you can use Merge by Distance from the Particle menu.

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.
