Bake Wire Image from UVs
|
|
|
|
Write a wireframe image from the UV coords and the the material color
|
|
|
|
This is usefull for laying out UV images on an unwrapped mesh.
|
|
|
|
Make sure your UV Coordinates do not overlap.
|
|
LSCM Unwrapper or archimap unwrapper work well to automaticaly do this.
