Yingying covers the basics for working with LookdevX in Maya and the workflow for USD.
LookdevX is a new material authoring system within Maya that relies on Open Source standards to build procedural materials that work across multiple renderers. LookdevX allows you to graph shading networks and create materials for USD objects.
Here, Autodesk’s Yingying Z introduces LookdevX and covers essential distinctions in the workflow from other material graphs.
The latest versions of Maya currently have a technology preview in LookDevX. The graph environment is similar to the Hypershade authoring environment in Maya, but you can author materials feasibly to have them work across multiple content creation tools.
