in hierarchy added a lodgroup with 3 lods to a cliff
reimported the cliff asset
in hierarchy added another lodgroup with 3 lods to a house
reimported the house
now simplygon keeps spawning jobs

it just ended, I know what is happening now for each mesh in the selection it is sending a job.
it would be good if the jobs were sent in // but I see they are sent sequentially
make them sent in // so the simplygon agent can process them concurently, I have 5 cores waiting for food ;)

on second thought, I think the way poly reduction is evaluated is causing problems: because each mesh's job is independent, there is no reference to the total % poly budget so a small polycount but important sphere will get decimated to a tetrahedron within LOD1 instead of remaining a sphere and eating polys elsewhere.
so there need to be an option to keep the meshes' in one job and let simplygon figure out budget like a big boy

How were you generating these LODs? It sounds like you are using the menu item to generate them?

And I'm not able to follow your example about total % poly budget. The quality is based on absolute quality from LOD0, so 0.5 is half the quality of that. The system isn't based on a poly count budget.

I took the liberty to rename this issue and mark it as a feature-request, since what you originally reported as bug was not actually the case.

yeah don't worry about that poly budget thing, that's what it does, sorta
