The recent release of LookdevX 1.3 has introduced the MaterialX data model. In this tutorial, Yingying will walk you through the MaterialX workflow and show you some of the new UI features. LookdevX is a material authoring plugin for Maya. It allows you to graph shading networks and create materials in both USD and MaterialX data model. With LookdevX, you can efficiently build materials that work across multiple renderers. The asset used in this tutorial were created by: Dusan Kovic (Surfacing) and Armando Sepulveda (Modeling) Link to the scene file and textures: https://areadownloads.autodesk.com/wdm/maya/files_for_MaterialX_data_model.zip

This is the second video of a 2-part series that introduces the procedural workflow for creating materials in LookdevX. This tutorial focuses on how to efficiently create various looks for a number of instances. Continuing from the stage created in part 1, Yingying will teach you how to create USD instances of the lamp, and how to automate the process of random material assignment. LookdevX is a new material authoring plugin for Maya. It allows you to graph shading networks and create materials for USD objects. With LookdevX, you can efficiently build procedural materials that work across multiple renderers.

This is the first video of a 2-part series that introduces the procedural workflow for creating materials in LookdevX. Using a paper lamp as an example, Yingying will teach you how to procedurally create a USD stage in Bifrost as a preparation for the material assignment, and how to create Arnold materials in LookdevX. LookdevX is a new material authoring plugin for Maya. It allows you to graph shading networks and create materials for USD objects.

This is the second tutorial of the Understanding Volumes series. In this video, 3D artist Yingying Z teaches you how to use an animated aero volume to drive particle movements in Maya’s Bifrost plugin. You’ll also learn how to set scales and colors based on voxel properties of a volume.

This is the first lesson of a series on volumes and their applications in Maya’s Bifrost plugin. In this tutorial, 3D artist Yingying Z teaches you the basics of Volumes, including voxels, signed distance and how to use them with fields and meshes to create interesting shapes and animation. 00:00 – Intro 00:27 – Voxels, fog density and signed distance field 06:24 – Volume & field: selective displacement 08:29 – Volume & field: animation 14:21 – Create texture from volume

Iterative constructs allow a computer to execute the same process repeatedly, which empowers artists to create scenes with a high level of complexity that can not be achieved otherwise. In this tutorial, 3D artist Yingying Z teaches you the basics of looping constructs in Bifrost, including auto-looping, for-each, iterate and do-while, and how to apply them to generate colorful animations.
