Output Mode (2D/3D)
While the pRender defaults to 3D output, it can be made to render a 2D image instead. This is
done with the 3D and 2D buttons on the Output Mode control. If the pRender is not connected
to a 3D-only or 2D-only node, you can also switch it by selecting View > 2D Viewer from the
viewer’s pop-up menu.
In 3D mode, the only controls in the pRender node that have any effect at all are Restart,
Pre-Roll and Automatic Pre-Roll, Sub-Frame Calculation Accuracy, and Pre-Generate frames.
The remaining controls affect 2D particle renders only. The pRender node also has a Camera
input on the node tree that allows the connection of a Camera 3D node. This can be used in
both 2D and 3D modes to allow control of the viewpoint used to render an output image.
Render and the Viewers
When the pRender node is selected in a node tree, all the onscreen controls from Particle
nodes connected to it are presented in the viewers. This provides a fast, easy-to-modify
overview of the forces applied to the particle system as a whole.
Pre-Roll Options
Particle nodes generally need to know the position of each particle on the last frame before
they can calculate the effect of the forces applied to them on the current frame. This makes
changing current time manually by anything but single frame intervals likely to produce an
inaccurate image.
The controls here are used to help accommodate this by providing methods of calculating the
intervening frames.
