Capture And Exports

Camera Controls

• Distribution: sphere/hemisphere/ring patterns
• Camera Count: total samples
• Elevation limits: minimum and maximum vertical angle
• Distance mode: auto or manual
• Focal length: camera lens in mm

Export Types

• RGB images: images/image_0000.png
• COLMAP: sparse/0/cameras.txt, images.txt, points3D.txt
• transforms.json: NeRF-compatible camera transforms
• Depth maps: depth/depth_0000.<ext>
• Normal maps: normals/normal_0000.exr
• Masks: masks/mask_0000.<ext> or GS-Lightning naming
• Proxy hulls: cleanup/proxy_hulls.json (for post-training splat cleanup)
• Validation report: validation_report.json (pre-capture + post-export checks)

Validation UX

• Capture Selected now opens a pre-capture validation dialog when warnings/errors are found.
• Scene Analysis > Validation Summary opens the same dialog without starting a render.
• Capture still blocks on validation errors, but warnings can be acknowledged and continued.

Blender 4.5 vs 5.0 Output Notes

Depth and object-index mask compositor outputs can differ by Blender major version:

Blender Version	Depth Extension	Object-Index Mask Extension
4.x / 4.5.1 LTS	.png	.png
5.0	.exr	.exr

transforms.json paths follow the captured output extensions automatically.

Alpha vs Object-Index Masks

• Alpha masks:
• Require transparent background in render settings
• Work with PNG/EXR image output
• Object-index masks:
• Set pass indices on objects
• Use Mask Source: Object Index

Coverage Analysis

1. Generate preview cameras.
2. Run coverage analysis or heatmap.
3. Increase camera count or adjust elevation if low coverage is reported.
