Learn how to apply a directional force to a liquid.
- [Voiceover] We want our fluid to push through the doorway…and into the room here.…Currently, if I press play, we'll see…that the fluid is simply falling under gravity.…We can imply a lateral velocity here,…using an accelerator node.…I'll press stop, rewind,…and we just need to have some polygon object…to act as the accelerator.…It's perfectly okay to use the same object…that is currently our emitter.…And that is the emitter doorway mesh.…Simply select that object,…and then also select the domain solver container.…
That's the top level container here,…Bifrost liquid one.…Hold down control, and click on that,…then go into the Bifrost menus,…you'll see there's an add section,…we want to add an accelerator, click on that.…Now, there is an accelerator props node…listed here in the outliner.…Select it, and open the attribute editor, control-A.…Because the geometry is flat and planar and has no volume,…Once again, we need to change the conversion type to shell.…
Down below that, we have the acceleration attributes.…And under geometry influence,…
