Creating LODs manually is a tedious task that can be sped up by creating multiple LODs simultaneously and fully automated thanks to InstaLOD's asynchronous processes.
InstaLOD supports automatic LOD generation for both static and skinned meshes.
To produce a LOD chain, first, create a new mesh operation profile by navigating
New Profile. Then double-click the
Default entry in the
Mesh Operations window and rename it into
LOD1. The default mesh operation optimizes a mesh to 50% of its original polygon count, as viable in the
Mesh Operation Settings. By right-clicking, the entry in the list and selecting
Duplicate, a copy named
LOD1_dupe is created that contains the same settings. Rename it to
LOD2 and change its target polygon count to a lower value. This can be repeated for as many LOD entries as necessary.
LOD0 is created by adding another entry and setting
Percent Triangles to
100%. Any input meshes processed by such a mesh operation are preserved as they are. The entry
LOD0 can be dragged to the top of the list so that all meshes and LODs are ordered correctly.
To create a LOD Group, move into the
Profile Settings where
LOD Group Settings can be located. Applying the
LOD Group Attribute will enable proper LOD behavior in applications that support it.
Mesh Operations window, press
Start to run the optimization. Once it's finished, tabs for each LOD entry can be found over the viewport with
LOD0 being active. When hovering over the tabs, the viewport toggles between the LOD entries. Click on a tab to lock the visibility.
Right-clicking a mesh operation entry allows to duplicate or delete it. To set up a LOD chain quickly, first, configure the settings of one mesh operation, duplicate it, and only adjust the target polygon count of the copied entries.
