InstaLOD for Blender uses InstaLOD Pipeline as backend for optimization operations.
InstaLOD Pipeline must be installed before you can start using InstaLOD for Blender.
Please refer to the InstaLOD Pipeline 2020 documentation on how to install InstaLOD Pipeline on your workstation.

InstaLOD for Blender supports authorizing licenses and displaying license info from within Blender.

Installing InstaLOD for Blender

Blender 2.82: Due to changes in script handling in Blender 2.82, rename ‘’ into ‘’ and copy the contents of the ‘InstaLOD’ folder directly into the addons folder.

On Windows: Copy the InstaLOD folder to your Blender addon user folder, normally found at C:\Users\<Username>\AppData\Roaming\Blender Foundation\Blender\<BlenderVersion>\scripts\addons.
On macOS : Copy the InstaLOD folder to your Blender addon user folder, normally found at /Applications/<BlenderVersion>/scripts/addons

Getting started with Blender

Once the integration’s script folder is copied to your Blender addon folder, you can start Blender.

To open the InstaLOD window go to the preferences panel and select ‘Add-ons’. Inside the add-ons panel search for InstaLOD and enable it. InstaLOD for Blender will now spawn inside the viewport in the properties panel (default keyboard shortcut ‘n’).
If you want to automatically initialize InstaLOD whenever Blender starts, go to the menu entry File > Defaults > Save Startup File.

On the first start of InstaLOD, it is necessary to point InstaLOD for Blender to the installation directory of InstaLOD Pipeline.
Click the folder button and browse to the InstaLOD Pipeline installation directory on your workstation.

If InstaLOD Pipeline was found in the specified directory, the window contents will change.
If your machine has already been authorized for InstaLOD you can start using InstaLOD for Blender now.
If your machine has not been authorized for InstaLOD yet you can enter your license information in the dialog to authorize your workstation.

Please refer to the InstaLOD Pipeline 2020 documentation for an overview of all features.

Optimizing a single mesh

To optimize a mesh select the mesh in the viewport or hierarchy. Select the OP-tab in the InstaLOD window and enter the percentage of triangles for the output mesh in the Percent Triangles text field.
Click the Optimize Selected Meshes button to optimize the mesh. Blender will export the geometry for InstaLOD and start the optimization.
Once the geometry has been exported, InstaLOD will execute the mesh operation asynchronously.

Both skeletal and static meshes are supported by InstaLOD for Blender.

The image above shows the UI of InstaLOD for Blender docked in the properties panel in the viewport.

Optimizing multiple meshes

Optimizing multiple meshes in a single operation with global optimization enabled allows the optimizer to consider all input
meshes when executing the operation. This results in the lowest visual deviation for the input meshes as a whole.
Global optimization is enabled by default, but can be disabled by unchecking the checkbox in the Advanced Settings found on the OP-tab.

Optimizing multiple meshes works identical to the optimization of a single mesh.
Select all meshes to be optimized in the viewport or hierarchy, enter the optimization target value, and click the Optimize Selected Meshes button to optimize all currently selected and visible meshes.

Creating batch operations

By clicking the Save as Batch-Profile button right of the mesh operation execution button, the current mesh operation settings will be saved as batch profile inside the directory of your InstaLOD Pipeline installation. On the Batch-tab saved profiles can be selected and executed on the current mesh selection in parallel. This is a great way to create a complete LOD chain with a single click.

Deleting batch profiles

To delete a saved batch profile, open the Batch-tab. Click the Delete Selected Batch Profiles button to delete all selected profiles.

Exporting settings and batch profiles for InstaLOD Pipeline

To export a profile that can be used with InstaLOD Pipeline without modification, configure your mesh operation and click the mesh Export As InstaLOD Pipeline Profile... button next to the operation execution button.
Another great feature of InstaLOD for Blender is the ability to create and export multi operation batch profiles for InstaLOD Pipeline.
To export a multi operation batch profile, open then Batch-tab and select all saved batch profiles that will be included in the multi operation.
Click the Export As InstaLOD Pipeline Profile... button and export the profile for InstaLOD Pipeline.

Profiles exported with InstaLOD for Blender have a hard-coded profile name of Blender. When queuing files with InstaLOD Pipeline, the profile needs to be specified:

InstaLODCmd -profile ExportedWithBlender.json -file Data/SM_Zetsuda_130k.fbx Build/SM_Zetsuda_Optimize.fbx Blender
