The biggest advantage of UDIMs is texture resolution. Instead of forcing an entire asset into a single 0\u20131 UV space (and shrinking shells until detail is lost), UDIMs let you spread UVs across multiple tiles so each part can keep meaningful texel density. In this video, we cover a practical UDIM unwrapping workflow in InstaMAT Studio: separate parts by material section, unwrap clean UVs, then distribute each section into its own tile.<\/p>\n
\nWith more UV space available, you can allocate resolution where it matters\u2014hero surfaces, decals, and areas that need crisp close-up detail\u2014without compromising the entire asset. This is especially useful on complex models where a single tile would require aggressive downscaling to avoid overlaps.<\/p>\n
As a secondary benefit, UDIMs naturally keep layouts clearer (each section has its own space), which can make baking, painting, and troubleshooting easier\u2014but the core win is preserving detail through higher effective resolution.<\/p>\n
In this video, we\u2019ll walk through a practical UDIM unwrapping workflow in InstaMAT Studio using the Element Graph and show how to take a complex model with no UVs and unwrap it for the UDIM workflow.<\/p>\n
