Mesh/Upload Model UI reference
Use the Upload Model window to upload COLLADA (.dae) files to Second Life. This window includes three tabs and preview section that is always visible.
The Preview area displays a preview of the selected model at various levels of detail. Use the standard camera controls to pan around and zoom your view of the model.
|Name||Name of the model being uploaded.|
|Level of Detail||Select a level of detail at which to preview the model.|
Weights and fees
Displays the model's calculated download, physics and server costs, its prim equivalent cost, and the resulting upload fee.
Level of Detail
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.
Select Level of Detail
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:
- Green - No problems detected. Ready to upload.
- Red - Too many vertices at this level of detail. Models at each level must have fewer vertices than the level above them.
Select from the Source dropdown how you will specify your model's LOD:
- Load from file
- Use LoD above

This tab is the second step in the model upload process.
A model's physics shape defines how it collides with other objects, and is typically simpler than its visual appearance to reduce computational cost. For example, a complex vehicle model might have a square physical box shape. NOTE: Models meant to be used as vehicles must not have a physics weight higher than 32.
Step 2: Analyze and Step 3: Simplify are not mandatory for creating a physics shape for your model, but can significantly decrease your model's physics weight.
After you make selections in this tab, click the Modifiers tab.
Step 1: Level of Detail
|Choose one...||Select a level of detail to automatically generate a physics model based on an existing visual level of detail:
Lowest or Low are adequate for most purposes and incur a relatively small physics cost.
|From file||Select this option to upload your own physical model from a .dae file. This gives you the greatest control over the model's physics shape. Click Browse to select a file.|
Step 2: Analyze
Select options in this section, then click Analyze.
|Method||Select a decomposition method for the model. Each method is best suited to a particular type of shape, because it will return the most accurate and least costly results for models of that type:
|Quality||Select how much combining and overlap reduction is performed on the hulls at the decomposition stage. High returns the best simplification results, but requires the most time to process. If you experience performance problems, try Preview setting first to confirm your smoothing and select Close Holes, then switch to High to get the best simplification results.|
|Smooth||Set the tolerance to which coplanar triangles are merged. The value is the angle between adjacent triangles for which merging is permitted. A value of zero allows some angle between triangles, resulting in gently-curving surfaces being flattened.
A lower Smooth setting results in a lower physics cost for objects with curved surfaces.
|Close Holes (slow)||Select to fill any holes in the physical representation of the model (if possible) to fix minor errors in the model. Selecting this option will also close intentional openings in objects: do not use for models that have intentional openings, such as door frames.|
Step 3: Simplify
Select options in this section, then click Simplify.
|Method||Select a simplification method:
|Passes||Increase this value to create results with fewer overlapping hulls and more accurate overall representation of your model's physical shape.|
|Detail Scale||Reduce this number to preserve more fine detail in your model during the simplification process. Larger values result in a decreased physics cost, but lower accuracy in the physics model. For many models, most of the simplification takes place at very low values, between 0.0 and 0.3, after which the physics model is reduced to a single hull.|
|Preview Spread||Move the Preview Spread slider (below the Preview pane) to explode your view of the hulls that comprise your physical model. Make sure the Physics box below the Preview pane is also checked. On objects with many hulls, this can help you to find and examine hulls that would not otherwise be entirely visible.|

This tab is the third step in the model upload process, in which you specify additional features on your model, such as textures.
When you have specified all the information you wish to on this tab:
- Click Calculate weights & fee, then review the resource weights, prim equivalent cost, and Linden dollar cost of your model.
- Click Upload to upload your model to Second Life.
