Objeto de fluxo de fumaça

Panel:Physics ‣ Smoke Type:Flow

Smoke Flow objects are used to add or remove smoke and fire to a Smoke Domain object.

To define any mesh object as a Smoke Flow object, add smoke physics by clicking Smoke in Properties ‣ Physics. Then select Flow as the Smoke Type. Now you should have a default smoke flow source object. You can test this by playing the animation Alt-A from the first frame. If your source object is inside your domain, you should see smoke.

Settings

Panel:Physics ‣ Smoke ‣ Settings Type:Flow

Tipo de fluxo

Fogo

Emit only fire. Note that the domain will automatically create some smoke to simulate smoke left by burnt fuel.

Fumaça

Emite somente fumaça.

Fogo e fumaça

Emit both fire and smoke.

Escoamento

Remove smoke and fire. Note that the shape of the outflow will use the object’s bounding box.

Fonte de fluxo

Fonte

This setting defines the method used to emit smoke and fire.

Malha

Create smoke/fire directly from the object’s mesh. With this option selected there two additional settings, Surface and Volume.

Superfície

Maximum distance in voxels from the surface of the mesh in which smoke is created (see voxel). Since this setting uses voxels to determine distance, results will vary depending on the domain’s resolution.

Volume

Amount of smoke to emit inside the emitter mesh, where 0 is none and 1 is Note that emitting smoke based on volume may have unpredictable results if your mesh is non-manifold.

Sistema de partículas

Create smoke/fire from a particle system on the flow object. Note that only Emitter type particle systems can add smoke. See Particles for information on how to create a particle system.

With this option selected, there is a box to select a particle system and one additional setting, Set Size.

Configurar tamanho

When this setting is enabled, it allows the Size setting to define the maximum distance in voxels at which particles can emit smoke, similar to the *Surface* setting for mesh sources.

When disabled, particles will fill the nearest voxel with smoke.

Velocidade inicial

When enabled, smoke will inherit the momentum of the flow source.

Fonte

Multiplier for inherited velocity. A value of 1 will emit smoke moving at the same speed as the source.

Normais

When using a mesh source, this option controls how much velocity smoke is given along the source’s normal.

Valores iniciais

Densidade absoluta

Maximum density of smoke allowed within range of the source.

Densidade

Amount of smoke to emit at once.

Diferença de temperatura

Difference between the temperature of emitted smoke and the domain’s ambient temperature. This setting’s effect on smoke depends on the domain’s Temperature Difference.

Cor da fumaça

Color of emitted smoke. When smoke of different colors are mixed they will blend together, eventually settling into a new combined color.

Taxa de chamas

Amount of «fuel» being burned per second. Larger values result in larger flames, smaller values result in smaller flames:

Example showing two fire sources. The object on the left has a Flame Rate of 5, while the one on the right has 0.3.

Sampling Subframes

Number of subframes used to reduce gaps in emission of smoke from fast-moving sources.

Example showing two fast-moving sources. The object on the left uses 0 subframes, while the one on the right uses 6.

Grupo de vértices

When set, use the specified Vertex Group to control where smoke is emitted.

Texture

Type:Flow Panel:Physics ‣ Smoke Flow ‣ Texture

When using a mesh as the Flow Source, you can use these settings to control where on the mesh smoke can be emitted from. These settings have no effect on outflow objects.

Usar texturas

When enabled, use the specified texture to control where smoke is emitted.

Exemplo

These settings are useful for effects like this:
