As a generalist that was Maya I written expressions and a the script. So if you are a non-programmer enjoy me, what is the best place to begin studying programming in Bifrost. I decided a very simple saying would be a helpful starting point for a means to recreate something I was familiar with in Maya but would be used as a tool to reuse in other scenes and utilize the strengths Bifrost offers. This will get you interested in exploring some of the other nodes in Bifrost. There are lots of interesting nodes in Bifrost which are simple to get and utilize as outputs in Maya.
Here’s a great Autodesk Knowledge Network article on using sin in expressions as well as links to other math nodes.
