“Frosty” shows how to get things into the Bifrost graph and back out again using the inputs and outputs.
One of the foundational concepts behind Bifrost in Maya is getting data in and out of the graph. While Input and Output nodes are simple things to grasp, both of those go much deeper than you’d think.
Check out this new tutorial from Youtuber “Frosty,” covering everything you want to know about input and outputs in Bifrost in Maya. The tutorial shows which things you can drag and drop into Bifrost and how you can manually create inputs via the node editor.
Also of note is how you can use the Bifrost Geo to Maya node to get things purely into the Maya viewport.
