To use after installation in blender;

1) select all objects you want lods for (works on multiple objects at a time)

2) in the viewport go to the side panel menu under the tab "LODMOD"

3) choose how many lods you want

4) choose what ratio you wish to decimate them (lower value = less verts)

5) choose if you wish to apply the modifier stacks automatically

6) choose if you wish to add the _LOD0 suffix to the original object

7) choose if you want to offset the LODs so you can see them in a lineup (default offset 0)

8) choose if you want your lods in neat collections named after the original objects

9) press the "Create LOD's" button and you're done!
