Learn about render points or an implicit surface.
- [Narrator] The Arnold renderer,…directly supports the liquid shape node,…also known as the bifrost shape,…so that we can render particles,…and implicit surface,…or a mesh, tessellated at rendered time.…In the Arnold section of the bifrost shape node,…we have some very cool options,…that allow us the visual fidelity…of classic bifrost meshing,…render times are about the same,…and we don't need to spend time and resources,…building a cache.…Behind the scenes, the liquid shape renders us…something called, the bifrost Procedural for Arnold.…
In this context, Procedural is a noun,…meaning type of Arnold primitive object.…Very importantly, these attributes,…for the bifrost shape node,…completely changed between the Maya 2018,…and the Maya 2018.1.…Make sure you're running 2018.1 or higher,…and M2A Arnold plug-in version 2.0.2, or higher.…You can check the current versions, in the menus,…under help, about Maya,…and Arnold, about.…
In this scene, I've prepared and cached a liquid simulation.…This scene picks up where we left off,…
