Osg mesh how to add LOD

[brunomartelli]

add the LOD helper, set it to the origion of model, call your LOD meshes LOD01, LOD02 etc. put them into the slots. The max min numbers indicate when the LODs will switch. so first would be say 0 - 500, second 500 - 1000 etc. The number is distance to viewer. empty slots will show up nothing, so you can make the mesh completely disappear

Select all the models and the LOD helper. export osgb, in export options select Export Helpers.

IDK how to change the LOD swap distance in Vizard (i woould love to know)
