Check out this cool new tutorial by Adrien Lambert, a CG Trainer and Lead Generalist at ILM. In this tutorial, Adrien shows how to make a setup that will allow you to make UV maps and layout them in 5 minutes max thanks to Houdini power. Adrien goes in-depth into transferring random color to geometry, partitioning the colored mesh into groups corresponding at one tile, converting the group into a name attribute, create a loop into every tile to unwrap and layout UVs, and more. According to Adrien, this tutorial is especially perfect for a Generalist workflow.
