# Shape Flow

# Installation

1. `cd custom_nodes`

2. `git clone https://github.com/avatechgg/avatar-graph-comfyui.git`

3. Install deps `cd avatar-graph-comfyui && python -m pip install -r requirements.txt`

4. Navigate to in your comfyui installation folder, open `comfyui/main.py` and add the following lines:
```py
def prompt_worker(q, server):
    e = execution.PromptExecutor(server)

    # This is a workaround since using blender as a python module, the bpy module has to be imported after in the custom thread, otherwise it will cause a segfault if imported in the custom nodes.

    # Add next line
    import global_bpy

    while True:
        item, item_id = q.get()
        # Add next line
        global_bpy.reset_bpy()
```

5. Restart comfyui

6. Run comfyui with enable-cors-header `python main.py --enable-cors-header` or (mac)`python main.py --force-fp16 --enable-cors-header`
