[How to create lightest possible LOD4]

Thank you so much guys, it turned out I was too tired and in my LOD1 mesh there was a material not used with any triangles. That caused the problem. Now all works. Thanks

[How to create lightest possible LOD4]

Hello, I have build 13k triangle furniture set that i will be placing in my home. All works fine except I cannot get LOD4 low enough. Auto generating allows me only 670tris , no lower for some reason. Then I created simple LOD4 mesh so that:

- main LOD and LOD4 have exact same number of materials used;

- materials appear in exact same order in both (sorted alphabetically, checked collada, yes - they really appear in same order);

- faces in LOD4 model are not tiny, they make up whole bounding box of high poly LOD model.

 

Now, when I try to upload it as LOD4 - i get this error which has been circulating over and over in this forum: "Material of model is not a subset of reference model".

So how can i make smallest possible LOD4 if autogenerating stucks at 670 and this custom LOD4 approach doesnt work?

Thanks in advance
