After Open the LoD Manager and clicked on Recalculate, then clicked Create All.
Set the LoD#1-3 eg. 940/80%, exit the LoD Manager Panel and trying to save the mesh model.
I noticed that the reduced mesh models are saved as the original.

By the way, the Mesh Reducer works.

Thanks, I have not fully understood the problem but we'll look into this and check if there's an issue with the 940/80% setting.

Thanks, I've no problem with setting , but if I try to save any reduced LoD meshes (eg: LoD#1 80% LoD#2 40% LoD#3 10%) after creating.

The saved mesh model is exactly the same as the original model 100%

We've checked, but can not confirm the problem. Can you contact the support and send them the model that could not be saved with LOD meshes?

Strange, not needed because it happens if an primitives model was used, too.

I recorded a video what exactly happens.

I think you've misunderstood the concept, it works exactly as intended. The different LOD stages are saved inside the same file. The engine then automatically switches between the different meshes depending on the distance to the camera/ view, it's an awesome feature!

Thanks Superku, finally works, the problem is on my side.

For my models I used _0 at file name end and therefore I don't see the differences.

@jcl, Problem solved and Thread can be moved or deleted, thanks.
