Particle System ‣ Emission

The Emitter system works just like its name says: it emits/produces particles for a certain amount of time. In such a system, particles are emitted from the selected object from the Start frame to the End frame and have a certain lifespan. These particles are rendered default as Halos, but you may also render this kind of particles as objects (depending on the particle system’s render settings, see Visualization).

The buttons in the Emission panel control the way particles are emitted over time:


The maximum amount of parent particles used in the simulation.


Blender uses this as starting point to produce random numbers during the simulation.

Quadro inicial

The start frame of particle emission. You may set negative values, which enables you to start the simulation before the actual rendering.


Quadro final para a emissão de partículas.

Tempo de vida

O tempo de vida (em quadros) das partículas.

Lifetime Randomness

A random variation of the lifetime of a given particle. The shortest possible lifetime is Lifetime × (1 - Random). Values above 1.0 are not allowed. For example with the default Lifetime value of 50 a Random setting of 0.5 will give you particles with a live span ranging from 50 frames to \(50 × (1.0 - 0.5) = 25\) frames, and with a Random setting of 0.75 you will get particles with live spans ranging from 50 frames to \(50 × (1.0 - 0.75) = 12.5\) frames.




Particle System ‣ Emission ‣ Source

Emit From

Defines how and where the particles are emitted, giving precise control over their distribution.


You may use vertex groups to confine the emission, that is done in the Vertex Groups panel.


Emits particles from the vertices of a mesh.


Emits particles from the surface of a mesh’s faces.


Emits particles from the volume of an enclosed mesh.


Your mesh must be Manifold to emit particles from the volume. Some modifiers like the Edge Split Modifier break up the surface, in which case volume emission will not work correctly!

Usar a pilha de modificadores

Take any Modifiers above the Particle Modifier in the modifier stack into account when emitting particles, else it uses the original mesh geometry.


Note that particles may differ in the final render if these modifiers generate different geometry between the viewport and render.


These settings control how the emissions of particles are distributed throughout the emission locations when emitting from either Faces or Volume.


Particles are placed at jittered intervals on the emitter elements.

Partículas por face

Número de emissões por face (0 = automático).

Montante de tremulação

Quantidade de tremulação aplicada a amostragem.


Particles are emitted from random locations in the emitter’s elements.


Particles are set in a 3D grid and particles near/in the elements are kept.

Inverter grade

Inverte o que é considerado objeto e o que não é.


Uses a hexagonal-shaped grid instead of a rectangular one.


Resolução da grade.


Adiciona um deslocamento aleatório para as localizações da grade.

Random Order

The emitter element indices are gone through in a random order instead of linearly (one after the other).

Not available for Grid distribution.

Distribuição uniforme

Particle distribution is made even based on surface area of the elements, i.e. small elements emit less particles than large elements, so that the particle density is even.
