Mix Studio can now turn one photo into an H3 orbit video and a Gaussian splat through Create → 3D, behind Experimental Features. The generation form uses the shared photo-picker and Balance/Quality styling; completed scenes stay with their normal Library item and generation settings, with a separate 3D thumbnail opening the dedicated viewer.

The local pipeline runs a roughly 12-second, first/last-frame-anchored orbit, RIFE 2× at 48 fps, COLMAP camera reconstruction, and Brush training. It preserves the orbit if reconstruction fails, scopes records to profiles and unlocked source items, reserves the GPU pipeline against competing app jobs, and verifies Windows dependency downloads. The viewer adds subject centering, distance clipping, separate-version further training, and documentation MP4 export with the source, orbit, and a real splat camera move. Generated geometry remains experimental.

This also adds optional native Comfy Kitchen attention for H3 and prepares v1.3.0 release notes, download-page copy, and authentic Qwen generation/editing and experimental 3D highlight media while retaining prior update cards.

Validation:

• Local suite: 1,336 passed, 2 skipped; BM Pro Windows suite: 1,334 passed.
• BM Pro app pipeline: 294 native frames → 587 frames at 48 fps, verified with ffprobe; 60/60 registered views; a completed 71,889-splat scene.
• Further training through the usual app: 5,000 → 10,000 steps, a separate 222,498-splat result, original PLY checksum unchanged.
• Exported and inspected a real 1280×842 documentation MP4, including the rendered splat camera move.
• Browser checks: normal gallery → dedicated 3D → return preserves gallery state and focus; 390 px mobile layout has no horizontal overflow.
• Same-seed camera LoRA comparison introduced more reframing/background changes, so no camera LoRA was added to the default pipeline.
