Check: UV Map Count

Version:

PreviousCheck: UV Map RangeNextCheck: Mesh Triangle Count

Last updated 2 years ago

Severity: Warning

Error message: Meshes must only have 1 UV map. Found <n> UV maps instead.

Description

More than 1 was found for the mesh.

This is not compatible with Ready Player Me assets and can lead to unexpected results.

Even though glTF files and the WebGL renderers support 2 UV maps, we currently only utilize one. Not all WebGL renderers adhere to the official glTF 2.0 specifications when it comes to UV maps.

Leaving out unnecessary UV maps keeps the file size low.

Ready Player Me supports requesting avatars with combined materials via a texture atlas which can have unexpected results when more than 1 UV map is present.

Automatic Fix

There are no automatic fixes available at this time.

Manual Fix

Remove any additional UV maps in the .
