CINEMA 4D R11 Quickstart – Thinking Particles
The particles should be created on the surface of the polygon. In order to do this the setup has to be extended
a little. Give the “Pstorm“ node a “Particle Birth“ output. This output contains various particles generated by
the emitter that will be “processed further“.
Next we need a “PSurfacePosition“ node (XPool / System Operators / Thinking Particles / TP Helpers). This node
creates random positions on a given polygon object. It has an “object“ text field in its Attribute Manager. Drag
the emitter surface into this field. You will also find a menu in the Attribute Manager that determines if the
particles will be emitted from the face, edges or points of the polygon. Leave the setting on “Face“ because we
don’t want the particles to be emitted only from the corners.
This node lets you arbitrarily select a polygon object as an emitter. It’s only important that the parametric object
is first made editable. Just for fun, try to generate snow emitting from a sphere.
We need another node which will tell the particles to orient themselves according to the “PSurfacePosition“
node’s position. This is what the “PSetData“ node is for (XPool / System Operators / Thinking Particles / TP
Standard).
