If you unwrap all UVs for your 3D model's textures, it is recommended that you take the time to ensure that none of the UVs overlap. While this can be time-consuming on 3D models you've created previously, you can keep this in mind when creating new models. If you work for non-overlapping-UVs right from the start, you won't have a great deal of extra work to do.

By survey, many of our customers want non-overlapping UVs in their unwrapped UVs. Below are the results of a survey TurboSquid conducted among 3D model customers in December 2010.

With symmetrical 3D models or models with repeating textures, it's less work for you to use a smaller texture and overlap the UVs. However, overlapping UVs create problems for customers who:

• Export to other applications like game engines or sculpting programs
• Create variations on different parts of the model with dirt, wear, or graffiti
• Change the textures or colors on opposite sides of the model, such as pockets on one side of a pair of pants

What Our Customers Say

Here are comments from our customers about overlapping UVs:

• "Sometimes you would like to paint over one part of the model and leave the other as is. With overlapping UVs this is impossible to achieve."
• "Art directors have very specific needs. Non-overlapping UVs let me paint in whatever is required from the director."
• "For generating normal maps, it's very important to not have overlapping UVs or pattern textures."

How to Remove Overlapping UVs

Each software package that has a tool for unwrapping UVs also includes tools for dealing with overlaps. See the videos below for information on how to remove overlapping UVs in 3ds Max and Maya.
