Trig Functions in Maya without Third-Party Plug-ins
Jan 7, 2020 Maya Rigging Python
By default Maya does not ship with any nodes to calculate trig functions. If you want to use a plug-in, you can use the great plug-in Maya Math Nodes written by Serguei Kalentchouk. If you want or have to use default Maya, there is still hope. I recently added trig function support to dge, my library that converts string math equations to Maya node networks. Using math and trig knowledge, we can recreate these functions with the nodes that come with Maya.

Space Switch Using Offset Parent Matrix
Jan 1, 2020 Maya Rigging
Maya 2020 introduced the offsetParentMatrix attributes to transform nodes. This attribute allows transforms to be driven directly with a matrix and can cut down the number of nodes and connections in your set ups. In this post I'll show how to set up space switching using the offsetParentMatrix attribute instead of constraints and extra transform nodes. A parent-child relationship is a simple matrix multiplication and can be replicated with a multMatrix node:
