2.1. Smallest Feature
This is by far the most important parameter with regards to the resulting Umbrafied model. The number in brackets (0.125 in this picture) is an approximation of the smallest geometric detail Umbra tries to preserve in the processing. It's relative to the Unity scale in units.
Please see this section to learn in depth how to use this parameter for best results.
|Number of LODs
The Auto-value generates an LOD hierarchy which ensures that the maximum number of visible triangles at runtime is capped, for any given scene.
Specify the number of LOD levels to compute. The most detailed LOD level will capture the smallest feature parameter that has been set, and subsequent levels of detail will capture the geometry at twice the previous level's smallest feature size. If you can get your scene to run at a satisfactory framerate with one level, there is nothing to be gained by computing and using more levels.
This changes the output texture resolution between preset values. Increasing texture size will slow down the computation.
|Enable Normal Maps||
Umbra can compute and include normal maps in the output geometry
|Enable Metal Glossiness||
Metal glossiness map can be used to define metallic surfaces in your output geometry. By toggling this option Umbra will take Metallic values from original geometry and generate optimized metallic textures for your output geometry.
If your scene has double-sided triangles, disabling this setting will be required to get correct results. Disabling this setting will also increase the output data size considerably.
This setting enables ambient occlusion in the computation. Ambient occlusion is baked into the diffuse texture. Note that this setting will significantly increase computation times, but has no effect on output size or runtime performance.
Optimize By Layer
Select whether to restrict optimization to specific layers. When enabled, Umbra ignores all objects that are not in the given layer. To learn about how to isolate objects into a specific layer in Unity, please see here.

The plug-in will not warn about overriding existing content in a view slot; you should always check before hitting Umbrafy that the view slot is either empty or has content you're happy to overwrite. This action cannot be undone.
Hit the Umbrafy button to begin export and upload. Refer to the project view on umbra.io to see Umbrafication progress before viewing content.
