Worldbuilder’s particle engine can produce some extensive redraw times. To save ourselves some time, let’s adjust one of the Waterfall’s Settings variables before proceeding.

In the Property Tree, select Settings.

Change the Particles per Frame value from 100 to 1. This will reduce the amount of calculations Worldbuilder will have to perform every time it updates its display in response to a given changed variable.

(As an alternative to resetting the Particles per Frame variable, you can also disable/enable the draw in wireframe mode feature; this will make the particles invisible until render time.)
