User Manual

You can also attach the following types of nodes to a pEmitter node to deeply customize a
particle system:
 Attach a 2D image to a pEmitter node to create highly customized particle shapes.
Make sure your image has an appropriate alpha channel.
 Attach a Shape3D or other 3D geometry node to a pEmitter node to create a more
specific region of emission (by setting Region to Mesh in the Region tab).
Customizing pEmitter nodes using mesh geometry to define regions and 2D images to define particle shape.
The above examples assume that you’ll output 2D renders to combine into the rest of a 2D
composition. However, because particle systems are fully 3D, you also have the option of
outputting your particle system in such a way as to be used from within other 3D scenes in your
composition.
Connecting a particle system to a Merge3D node so the particles
are subject to lighting and shadows within a 3D scene.
The Output Mode of the pRender node, at the very top of the controls exposed in the Inspector,
can be set to either 2D or 3D, depending on whether you want to combine the result of the
particle system with 2D layers or with objects in a 3D scene.
