SDF EmitterEmit particles that fill the volume of a mesh.
This node generates particles in a filled volume inside of an input 3D object. This requires that the input object is converted to a 3D signed distance field representation. Objects with animation or deformation are not supported. Useful for generating particles for fluid or physical simulations that need to be evenly spaced within a volume.
A 3D Object node must be connected to the Object Node input for this node to be effective.
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
|Position X||Move along the local x-axis.|
|Position Y||Move along the local y-axis.|
|Position Z||Move along the local z-axis.|
|Rotation Heading||Rotate around the local y-axis.|
|Rotation Pitch||Rotate around the local x-axis.|
|Rotation Bank||Rotate around the local z-axis.|
|Scale X||Scale along the local x-axis.|
|Scale Y||Scale along the local y-axis.|
|Scale Z||Scale along the local z-axis.|
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
|Position X||Toggle inheritance of the X Position from the parent.|
|Position Y||Toggle inheritance of the Y Position from the parent.|
|Position Z||Toggle inheritance of the Z Position from the parent.|
|Rotation Heading||Toggle inheritance of the Rotation Heading from the parent.|
|Rotation Pitch||Toggle inheritance of the Rotation Pitch from the parent.|
|Rotation Bank||Toggle inheritance of the Rotation Bank from the parent.|
|Scale X||Toggle inheritance of the X Scale from the parent.|
|Scale Y||Toggle inheritance of the Y Scale from the parent.|
|Scale Z||Toggle inheritance of the Z Scale from the parent.|
|World Position Only||Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.|
|Inherit Time||Toggle inheritance of time from the parent.|
These properties control the core behaviours of the node.
