I'm bringing some cool features

Improved LOD Mesh Generation:
The algorithm was greatly improved to produce much higher quality LOD's with fewer number of triangles than before. The model on the right has 50% triangle reduction, with no visible quality loss.
   

Theater Mode:
Preview all assets at the same time.
   

Material Atlas creation:
Merge multiple materials together to improve rendering performance.
   

Thanks for your feedback
Yes you can delete/unpublish the old files. Currently the editor keeps them as a backup in case you want to recreate the Atlas again using different settings.

Yes the newly generated object meshes automatically have the Atlas material set.

Just added a helpful commit to automatically handle remove/publishing of original elements.

Nice update!

Very nice update, there have been some nice performance based updates appearing recently which is great. Many thanks!
