Emissão
Reference
- Panel
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:
- Número
The maximum amount of parent particles used in the simulation.
- Semente
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.
- Fim
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.

- Emit From
Defines how and where the particles are emitted, giving precise control over their distribution.
Dica
You may use vertex groups to confine the emission, that is done in the Vertex Groups panel.
- Vértices
Emits particles from the vertices of a mesh.
- Faces
Emits particles from the surface of a mesh’s faces.
- Volume
Emits particles from the volume of an enclosed mesh.
Dica
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.
Nota
Note that particles may differ in the final render if these modifiers generate different geometry between the viewport and render.
- Distribution
These settings control how the emissions of particles are distributed throughout the emission locations when emitting from either Faces or Volume.
- Tremulado
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.
- Random
Particles are emitted from random locations in the emitter’s elements.
- Grade
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.
- Hexagonal
Uses a hexagonal-shaped grid instead of a rectangular one.
- Resolução
Resolução da grade.
- Random
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.
