Learn about enabling churn, curvature, and age.
- At this point in our work flow,…we've defined the initial conditions for the simulation.…Before writing a user cache, I want to show you…a few interesting fluid properties that are…disabled by default in this version of Maya.…They're found in the liquid properties container.…Select that from the outliner.…And in the attribute editor, scroll down.…And near the bottom you'll see optional channels.…Open that up.…And we have three switches here, curvature, turn, and age.…
Turn all of those on.…These are super cool attributes.…Once these are enabled, then curvature, the amount of turn,…or the age of particles can control any shader…property such as color or transparency.…We'll use this later when we look at bifrost channel nodes.…These switches need to be on before we write a user cache.…That's where to find those important optional…bifrost channels, and it finishes the chapter…on optimization and fine tuning.…
In the following chapter we'll work with caches and meshes.…
