Vector Fields 1
Writing custom vector fields is pretty easy in VOPs. You can leverage the multiple noise functions Houdini offers, easily create vortices and whirling clouds, and with just a bit more effort bring in curves and use them as paths which the field can orbit around or follow along. Whip up an additive shader and you can get very nice results… or export the fields to use in Unreal or some other game engine. I plan on eventually offering a number of free static vector fields here on the site for game effects artists, but for now here are some basic test renders, cheers.
