How to Edit 3D Scenes with Instruct-NeRF2NeRF

Welcome to your guide on utilizing Instruct-NeRF2NeRF for dynamically editing 3D scenes using intuitive instructions! Whether you’re a hobbyist or a professional, this article will walk you through the installation steps, usage, and troubleshooting tips in a friendly manner. Let’s jump right in!

Installation Steps

For getting started, you’ll need to set up Instruct-NeRF2NeRF which builds on the foundations of Nerfstudio. Here’s how to do it:

1. Install Nerfstudio Dependencies

Instruct-NeRF2NeRF requires several dependencies. The most vital ones are:

• PyTorch
• tinycudann

To set up your environment, follow the instructions here up to the installation of tinycudann.

2. Installing Instruct-NeRF2NeRF

Once the dependencies are in place, install Instruct-NeRF2NeRF using the command below:

pip install git+https://github.com/ayaanzhaque/instruct-nerf2nerf

If you prefer to work with the code directly, you can clone and install the repo with the following commands:

git clone https://github.com/ayaanzhaque/instruct-nerf2nerf.git
cd instruct-nerf2nerf
pip install --upgrade pip setuptools
pip install -e .

3. Checking the Install

To verify your installation, run the command below and check that in2n is listed:

ns-train -h

Using Instruct-NeRF2NeRF

Now that you have everything set up, let’s dive into how to edit a NeRF!

First, you need to train a regular NeRF scene using your own dataset:

ns-train nerfacto --data PROCESSED_DATA_DIR

After training, the model checkpoints will be saved. You’ll need to locate the nerfstudio_models folder. For editing, use the command below:

ns-train in2n --data PROCESSED_DATA_DIR --load-dir outputs/nerfstudio_models --pipeline.prompt prompt --pipeline.guidance-scale 7.5 --pipeline.image-guidance-scale 1.5

Ensure that your PROCESSED_DATA_DIR remains consistent with the path used during the initial training.

Training Notes

Here are a few things to keep in mind while training:

• Use images with a resolution not exceeding 512 to avoid out-of-memory (OOM) errors.
• Using multiple GPUs can speed up training; assign InstructPix2Pix to a different GPU.
• Experiment with different memory configurations based on your GPU capabilities.

Troubleshooting

If you find that the edits aren’t turning out to your satisfaction, it may be due to the limitations of InstructPix2Pix with your images or prompts. Here are a couple of troubleshooting strategies:

• Try editing one of your training views in 2D first using Instruct-Pix2Pix available at this link.
• Take a look at more tips for good edits found here.
