For an overviewe of mesh upload, see this page.
This tab is the first step in the model upload process, in which you specify levels of detail for your model. Levels of detail (LOD) determine how the model looks at various distances. As you get farther away from a model, it renders in less detail to boost performance.
Preview your model's automatically generated levels of detail on the Level of Detail tab by clicking High, Medium, Low, or Lowest. Notice how the object's complexity is reduced at each level.
After you make selections in this tab, click the Physics tab.
Click High, Medium, Low, or Lowest to preview and modify your model's various levels of detail (LOD). The status indicator color will show the whether your model is suitable for upload:
Select from the Source dropdown how you will specify your model's LOD:
Provides options for generating surface normals on your model, affecting its shading and appearance of “hardness” along edges between vertices.
Adjusts the smoothness of the model. Increase this value to soften the hard, “faceted” look of models with relatively few vertices.
