Unwrap UV2 of each selected object

[Vinc3r]

[Vinc3r]

at least two options :

• classic unwrap (user have to make sure that seams correctly assigned) followed by packing
• smart unwrap

now that Blender 2.8 have multiple objects edition availabled, maybe just a button to check/fix if some objects doesn't have UV2

import bpy

# create UV2
for obj in bpy.context.selected_objects:
    uvChans = obj.data.uv_layers
    if len(uvChans) < 2:
         uvChans.new(name="UV2")

# remove UV2
for obj in bpy.context.selected_objects:
    uvChans = obj.data.uv_layers
    if len(uvChans) > 1:
         uvChans.remove(uvChans[1])
