    Hi everyone,

    I have created a model with Blender that is composed by different static objects. Some of these objects need to have LOD because of high number of polygons. To simplify my case, I have created a simple model to show you. It is an fbx (created with Blender, as I said) that has the following tree when a prefab is created importing it:

    The problem is that Unity, automatically creates a LOD Group for "ModelExample" and it is working for the whole model at same time. If camera is close to ModelExample then Cylinder_LOD0 and Sphere_LOD0 are showed, and when the camera is far to ModelExample, Cylinder_LOD1 and Sphere_LOD1 are showed, both at same time.

    I can solve the problem manually removing LOD Group from ModelExample and I creating one LOD Group for Cylinder and another for Sphere, adding manually also meshes LOD0 and LOD1 for each level.

    For this simple model is not a problem to do it manullay, but it is annoying in a model with a lot of objects that need to have LOD.

    Is there any way to do it automatically? Maybe I'm missing some nomenclature, project option or an option when I exported the model from Blender, but I was searching for a solution and I don't find anything.

    Thanks in advance
