Offering a look at the relationship between UV pixel density and texture resolution in Autodesk Maya 3D Generaist and Art Director Timothy Hanson shows how to maximize texture resolution in you projects by using a multi-tile UV workflow.

Paying close attention to pixel density and maximizing UV space, you can exponentially increase texture resolution for your texture maps

By comparing two spheres in a Maya scene, one with an 8k texture applied to it, and the other sphere has six 2k texture maps applied using a Muti-Tile UV workflow, Timothy easily demonstrates the benefit of having a multi-tile setup. Timothy also walks through creating a muti-tiled UV set up in Maya, providing some example shading network setups.
