Install requirements using following scripts.
git clone https://github.com/modelscope/RichDreamer.git --recursive
conda create -n rd
conda activate rd
# install dependence of threestudio
pip install -r requirements_3d.txtwe also provide a dockerfile to build docker image or use our built docker image.
sudo docker build -t mv3dengine_22.04:cu118 -f docker/Dockerfile .
# or use our built docker image
sudo docker pull registry.cn-hangzhou.aliyuncs.com/ailab-public/aigc3dDownload pretrained weights.
- MultiView Normal-Depth Diffusion Model (ND-MV)
- MultiView Depth-conditioned Albedo Diffusion Model (Alebdo-MV)
Or your can download weights using the following scripts.
python tools/download_nd_models.py
# copy 256_tets file for dmtet.
cp ./pretrained_models/Damo_XR_Lab/Normal-Depth-Diffusion-Model/256_tets.npz ./load/tets/
# link your huggingface models to ./pretrained_models/huggingface
cd pretrained_models && ln -s ~/.cache/huggingface ./if you cannot visit huggingface to download SD 1.5, SD 2.1 and CLIPs, you can download SD and CLIP models from aliyun and then put $download_sd_clip file to pretrained_models/huggingface/hub/.
mkdir -p pretrained_models/huggingface/hub/
cd pretrained_models/huggingface/hub/
mv /path/to/${download_sd_clip} ./
tar -xvf ${download_sd_clip} ./Make sure you have the following models.

If you using above script to download SD and CLIP models, you do nothing, if you download via huggingface api, in first run, you need to set TRANSFORMERS_OFFLINE=0 DIFFUSERS_OFFLINE=0 HF_HUB_OFFLINE=0 in *.sh and it will connect hugging face and automatic download models.
# Quick Start, Single A-100 80G
python3 ./run_nerf.py -t $prompt -o $output
# Run from prompt list
# e.g. bash ./scripts/nerf/run_batch.sh 0 1 ./prompts_nerf.txt
# We also provide run_batch_res256.sh to optimize using high-resolution rendering images to achieve better results, but it will consume more memory and time.
bash ./scripts/nerf/run_batch.sh $start_id $end_id ${prompts_nerf.txt}
# If you don't have an A-100 device, we offer a save memory version to generate results.
# For single GTX-3090/4090, 24GB GPU memory.
# e.g. bash ./scripts/nerf/run_batch_fast.sh 0 1 ./prompts_nerf.txt
# or e.g. python3 ./run_nerf.py -t "a dog, 3d asset" -o ./outputs/nerf --img_res 128 --save_mem 1
bash ./scripts/nerf/run_batch_fast.sh $start_id $end_id ${prompts_nerf.txt}
# or using:
python3 ./run_nerf.py -t "$prompt" -o $output --img_res 128 --save_mem 11. Rendering High-resolution:
We found that optimizing a high-resolution DMTet sphere directly is more challenging compared to the NeRF method. For example, both Fantasia3D and SweetDreamer require 4 or 8 GPUs for optimization, which is difficult to obtain for most individuals. During the experimental process, we observed that optimization becomes significantly more stable when we increase the rendering resolution of DMTet, such as to 1024. This trick allows us to optimize from DMTet using only a single GPU, which was previously not feasible.
2. PBR Modeling:
Fantasia3D offers three strategies for conducting PBR modeling. If you Do Not require generating models that support relighting and only aim for enhanced realism, we recommend using the sampling strategy fantasia3d_2. Otherwise we suggest you to use fantasia3d strategy_0 with our depth condition albedo-sds.
# Quick Start, Single A-100 80G
python3 ./run_dmtet.py -t "$prompt" -o $output
# Run from prompt list
# e.g. bash ./scripts/nerf/run_batch.sh 0 1 ./prompts_dmtet.txt
bash ./scripts/dmtet/run_batch.sh $start_id $end_id ${prompts_dmtet.txt}
# If you don't have an A-100 device, we offer a save memory version to generate results.
# For single GTX-3090/4090, 24GB GPU memory.
# bash ./scripts/dmtet/run_batch_fast.sh 0 1 ./prompts_dmtet.txt
bash ./scripts/dmtet/run_batch_fast.sh $start_id $end_id ${prompts_dmtet.txt}This work is built on many amazing research works and open-source projects:
Thanks for their excellent work and great contribution to 3D generation area.
We would like to express our special gratitude to Rui Chen for the valuable discussion in training Fantasia3D and PBR modeling.
Additionally, we extend our heartfelt thanks to Chao Xu for his assistance in conducting relighting experiments.
