Spatial &amp; Physics LoRA (MiniMax-H3)Spatial reasoning and physical logic LoRA, trained on MiniMax-H3 (Comfy-Org/MiniMax-H3). It enables the base model to learn spatial relationships and physical motion of solid objects (collision, stacking, falling, occlusion, etc.)This LoRA focuses strictly on object physics.It is currently in the training and testing phase. The LoRA remains somewhat unstable due to issues with some training footage and labeling. A retraining run is planned for the next phase to fix these problems. The LoRA is usable at present; it moderately enhances physical feedback on top of the base model. The latest retrained version is wushu_spatial_physics_clean_3000_pruned.safetensors.Video ComparisonsTests using this LoRA show improved realism and physical logic across generated videos, such as realistic feedback from object collisions. It also works well for fight scenes to achieve realistic character collision effects.Wushu fight clip with Spatial &amp; Physics LoRA (strength 0.3)Wushu fight clip without Spatial &amp; Physics LoRA (identical prompt)Other test videos (wushu_spatial_physics_v2_3000.safetensors)Usage Instructions (ComfyUI)Download the *.safetensors file and place it into ComfyUI/models/loras/Load via LoraLoader, recommended strength: 0.8~1.0Describe object motion using spatial and physical language in promptsKeyword Library (extracted from training data)① Subjects / Scenesseveral colored objectsrigid objectselastic objectsmetal objectsa ball / ballsbilliard ballsobjectson a tablein a synthetic scene② Physical Behaviorscollision / collidinga single collision between objectsbouncing / reboundwith visible impact and bouncewith minimal bouncerolling into a wallscatteringmomentum transferin motion③ Spatial Consistency Phrases (Critical!)clear spatial layoutvisible depthconsistent trajectoriesgravity-consistent / gravity-consistent movementgravity-consistent rebound trajectoriesobjects maintaining spatial relationshipsrealistic restitutionrigid collision with momentum transferRecommended Negative PromptNegative prompts were empty during training (no negative samples learned). It is recommended to only add quality/physical negative terms and avoid content conflicting with physical rules:blurry, distorted, low quality, jittery motion, objects passing through each other, objects floating without gravity, morphing shapes, inconsistent lighting, flickeringPrompt Examples (ready to use)Collisionseveral colored objects, a single collision between objects, metal objects with rigid, elastic collisions, clear spatial layout, visible depth, objects maintaining spatial relationships in a synthetic sceneseveral colored objects, objects colliding with visible impact and bounce, clear spatial layout, gravity-consistent trajectoriesobjects colliding with visible impact and bounce, clear spatial layout, gravity-consistent trajectoriesBounce / ReboundElastic objects bouncing with realistic restitution, clear spatial layout, gravity-consistent rebound trajectoriesobjects bouncing with realistic restitution, clear spatial layout, gravity-consistent rebounda ball rolling into a wall and rebounding with minimal bounce, clear spatial layout, visible depth, rigid collision with momentum transferMulti-object Scattering / Billiardsbilliard balls colliding and scattering on a table, momentum transfer between balls, clear spatial layout, visible depthseveral balls on a table, a ball striking the group, momentum transfer, balls scattering with realistic collision, clear spatial layout, gravity-consistentTrajectory / No CollisionRigid objects in motion with clear spatial layout, consistent trajectories, gravity-consistent movement and visible depthseveral colored objects, objects moving with consistent trajectories, no collision, clear spatial layout, visible depth, objects maintaining spatial relationships in a synthetic sceneFree Template (replace behavior keywords)a ball thrown across the scene, [parabolic arc / gravity-consistent trajectory], clear spatial layout, visible depthtwo balls colliding in mid-air, clear spatial layout, consistent trajectories, gravity-consistent rebound, visible depth
