frame in MiniMax gives fantastic results (Activity: 2263): A user shared a MiniMax-H3 LoRA for generating locked-subject 360° orbit shots from first/last-frame conditioning: pablodawson/MiniMax-H3-360-Orbit-LoRA. The prompt explicitly constrains the scene to a frozen instant—no object/pose deformation, no drifting, no continued action—so that camera parallax is the only motion source, targeting cleaner pseudo-volumetric outputs suitable for downstream reconstruction workflows.
