FixAnything is a single generalist video model that repairs rendering artifacts from any 3D representation — 3DGS, NeRF, meshes, or sparse point clouds — by repurposing a pretrained video diffusion model with minimal modification and finetuning.

Model

This repository holds the FixAnything weights: a rank-64 LoRA on top of Wan2.1-I2V-14B-480P.

File	Description
`fixanything_lora.safetensors`	LoRA weights (rank 64) for the Wan2.1-I2V-14B DiT

The Wan2.1-I2V-14B-480P base model is required and is downloaded separately (see the code repository).

Usage

bash

git clone https://github.com/kvuong2711/fix-anything.git && cd fix-anything
# ... install (see README) ...
huggingface-cli download kvuong2711/fix-anything fixanything_lora.safetensors --local-dir checkpoints
python scripts/run_inference.py --input examples/dl3dv_3dgs/input.mp4 --output_dir outputs/dl3dv_3dgs
