I'm using the beach (modified plain w/ textures applied) as the canvas and another plain with an Ocean modifier as the brush. All is visible and seems to work in Solid View when scrubbing the Time Simulator of the Ocean modifier.
And, I can successfully render a single image (Dynamic Paint shows up) at any random time.
The problem is with key framing the Time Simulator on the Ocean modifier. Although the Dynamic Paint animation seems to work in Solid View, it disappears after the first frame upon rendering the animation.
I'm stumped and have no idea how to fix this. It leaves me wondering if I've missed something fundamental.
I'd greatly appreciate some help.
