The Mesh Preview window allows meshes to be viewed in one of the following ways:

Shaded

A simple shaded preview of the Mesh.

When the mesh has multiple sub-meshes, they are tinted with unique colors. The colors are listed in the top inspector part for each submesh:

UV Checker

Previews a Mesh with a checkerboard texture applied. You can use the slider next to UVChannel dropdown to adjust the tiling of the texture.

UV Layout

Previews unwrapped UVs. Any UV Channel can be previewed, if available. The view can be zoomed and panned, and initially shows 0..1 UV range.

Vertex Color

Previews Vertex Colors of a Mesh.

Normals

Preview Mesh Normals. We've opted to not displays normals as tiny vectors poking out of vertices, since it feels like without full-on navigation inside the preview window, they would just be a mess for non-trivial meshes.

Tangents

Preview Mesh Tangents. We've opted to not displays tangents as tiny vectors poking out of vertices, since it feels like without full-on navigation inside the preview window, they would just be a mess for non-trivial meshes.

Blendshapes

Preview Mesh Blendshapes. An additional drop down is displayed when this option is selected where you can choose which blendshape to display.
