But you can edit **by default** multiple objects since Blender v2.8 right? Why still using this addon?

ok! (I've forgot to mention I've play with some exporter options too), thanks for the clarify. So wait&see :)

low priority

check how gltf exporter works, it use autosmooth conversion

checkbox to enable/disable this filter idea: when detecting an instance (users > 1), removing all objects using this user, then add the current selected

```python import bpy uv_chan = 0 for obj in bpy.context.selected_objects: if len(obj.data.uv_layers) == 2: uv_chan = 1 obj.data.uv_layers.active_index = uv_chan bpy.ops.object.mode_set(mode='EDIT') bpy.ops.uv.select_all(action='SELECT') bpy.ops.uv.seams_from_islands() bpy.ops.object.mode_set(mode='OBJECT') ```

yep it doesn't detect these data yet. no idea when i will have the skills need for this :)

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

```python 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)...
