$checkuv

$checkuv is a QC command available in Source 2013. It checks the UVs of meshes and prints out messages if the checks fail.

Syntax

$checkuv <0to1> <overlap> <inverse> <gutter [res] [min]>

0to1

Checks that all UVs are in the [0, 1] range

overlap

Checks that all polygons in UV do not overlap

inverse

Check that all polygons in UV have the correct winding, i.e. the cross product of edge AB x BC points the right direction

gutter

Checks that the distance between edges in UV islands is a minimum number of pixels for a given texture size

Note:gutter does not function as it has not been implemented
