Install

Requirements

• Blender 4.5.1 LTS or 5.0.0 (currently validated in CI)
• Windows recommended for training backend integration
• Optional: conda environments for training backends

Addon Installation

Use the packaged addon zip named gs_capture_addon-<version>.zip. Do not use GitHub's auto-generated repository source zip (blender-synthetic-data-capture-*.zip), because Blender reports Modules Installed () and no addon entry appears.

1. Open Blender.
2. Go to Edit -> Preferences -> Add-ons.
3. Click Install... and select gs_capture_addon-<version>.zip.
4. Enable Blender Synthetic Data Capture.

Optional Backend Preferences

Open Edit -> Preferences -> Add-ons -> Blender Synthetic Data Capture.

Set paths/env names only for backends you plan to use:

• 3D Gaussian Splatting
• Path to repo containing train.py
• Conda env name
• Nerfstudio
• Conda env name
• GS-Lightning
• Path to repo containing main.py
• Conda env name
• gsplat
• Path to gsplat/examples containing simple_trainer.py
• Conda env name

Verify Installation

1. In 3D Viewport press N.
2. Open the GS Capture tab.
3. Confirm capture panels load without errors.
