The emitter's basic properties can be changed here.

 

 

Simulation

The first entry is used to specify how a node contributes to a scene. The default option is “Active” and tells RealFlow that the currently selected node will be considered during simulation. “Inactive” disables it and the node is greyed out. “Cache” is of special importance, because with this method it is possible to read already simulated data from disk and use them in a new simulation pass. The cached item will not be affected by forces or other nodes anymore. On the other hand, a cached node is still able to influence other bodies. In the "Nodes" panel, cached nodes are displayed with a yellow font.

Position

Please bear in mind that this parameter only influences the position of the emitter's viewport symbol. The emitter itself is placed and scaled by the attached emission object. "Position" values are given in metres [m].

Rotation

In combination with Hybrido emitters, this parameter determines the direction of emission. An arrow at the emitter's viewport icon indicates this direction. "Rotation" values are given in degrees [deg].

Scale

The final size of the Hybrido emitter is determined by the attached emission object. “Scale” changes have absolutely effect on the emitter. "Scale" values are given in metres [m].

Shear

With this parameter it is possible to create a spatial distortion of a node. Hybrido emitters are not affected by “Shear”. "Shear" values are given in metres [m].

Parent to

Nodes can be bounded to other objects, forcing them to follow their motions and rotations. By default, the associated emitter object is parented to the emitter node.

Color

In many cases it is required to differentiate nodes in the viewport to avoid confusion. By simply applying a colour you can separate similar or equal nodes from each other visually. In Python, "Color" values are defined from RGB values between 9 and 255; RealFlow Graphs and C++ use a 16-bit notation with values between 0 and 65535 plus a 8-bit Alpha channel ranging between 0 and 255.
