Fetch
particle node
Imports particle streams from other networks.
See also: Collect, POP Network
This operator lets you import particle primitives from other networks and merge them into the current stream.
Parameters
|
Transform Object |
The object to transform the imported streams relative to.
|
|
Align Events in World Space |
Events such as births and collisions of fetched copies will occur in the same world locations as for the original stream. However, the directional attributes such as velocity will not automatically be aligned (to achieve that, set Transform Object to “.”). |
|
Number of POPs |
Set this to the number of particle primitives you want to import. The parameter editor will show this number of fields for you to specify POP nodes to import. |
|
Enable Fetch # |
Turn this off to disable import of a POP node/network. |
|
POP # |
The path of a POP node or POP network to merge. If you specify a POP network is specified, the node with the cook flag set will be imported. A blank path is ignored. |
Local variables
Standard POP local variables

A collision for this particle was detected (for example, by the Collision POP) during the processing of this timestep (that is, this iteration of the particle simulation). This variable is cleared at the beginning of each timestep. Note that the collision POP actually detects any collisions which would have occurred the during the previous frame. |
