blender_decimate_modifier

Decimate modifier script that decimates models in a directory and overwrites them after decimating to the given ratio.

Steps to decimate models

Note: Currently tested only on .dae models and using Collapse decimation type on bpy 3.6

1. Install python >= 3.10

2. Create a virtual environment (required only if you have multiple python version)

   python3.10 -m venv blender_ws

3. Source the venv

   cd blender_ws

   source ./bin/activate

4. Create directories scripts, wheels and download bpy 3.6 and place it in the wheels directory

   mkdir wheels

5. Then install the wheel in venv

   cd wheels

   pip install bpy-3.6.0-cp310-cp310-manylinux_2_28_x86_64.whl

Once you've completed the installation, place the decimate modifier script in the scripts directory.

Change the below mentioned variables according to your needs

decimate_ratio, min_number_of_faces, path_to_model_directory

decimate_ratio - The ratio in which the model must be decimated.

min_number_of_faces - The minimum number of faces a model should have if it's to be decimated (just to preserve the model's shape)

path_to_model_directory - The path to the directory containing the .dae models.

1. The scripts will search for all the .dae files in the given directory

2. Caution: The script overwrites on the same path after decimating the model so if you need your original models make sure you have a copy of it.

Running the script

1. Once above steps are completed go the the scripts directory and execute the following command.

   blender -b -P decimate_models.py

Once completed your models should be decimated and placed in the same location.
