A system comprises an encoder configured to compress and encode data for three-dimensional visual volumetric content. To compress the 3D visual volumetric content, a compressed mesh is generated as well as compressed attribute information. Also, texture coordinates indicating a mapping between the vertices of the mesh and the attributes are signaled. However, in some situations a resolution used for the texture coordinates and a resolution used for the attributes may differ, in which case the respective resolutions are signaled. A decoder determines how to adjust the texture coordinate to attribute value mapping to account for the differing resolutions.
