VAM-Cross two-camera MimicVideo Video2World LoRA

This private repository contains the trainable-only Video2World LoRA checkpoint from iteration 200 of v2w_panda_level2_widowx_texture_2cam_hstack_from_widowx250_video_fused_f0cea76_lora_r256. The source run has termination status unknown; the selected four-component checkpoint set was verified before selecting the model weight.

• Source iteration: 1060

This is an adapter checkpoint, not a standalone fused model. Load the exact initial Video2World backbone above first and then apply this LoRA checkpoint. For fused_video2world_dit, the initial checkpoint already includes the earlier WidowX/Bridge LoRA fusion; loading the original Bridge backbone instead would be incorrect.
