Interface
The user interface appears in the parameters panel, on the right side of the
Particle View dialog.
Use At Caches particle motion when playing back in the viewports, or at
render time, or both. Default=Viewport.
IMPORTANT Choose the Viewport/Render option only when using the same
number of particles in the viewports and for rendering (see
Quantity Multiplier
group
on page 2832). Otherwise, unpredictable results can occur.
