obj2mjcf 0.0.4

A tool for converting Wavefront OBJ files into MuJoCo sub-meshes grouped by material.

obj2mjcf

A tool for converting Wavefront OBJ files to multiple MuJoCo meshes grouped by material.

Currently, MuJoCo does not support OBJ files with groups or objects (i.e., o or g). Furthermore, only 1 material can be assigned per mesh. This tool is designed to split such OBJ files into sub-meshes grouped by material. The resulting sub-meshes can then be used as a drop-in replacement for the original OBJ file. The result is vastly enhanced visuals for your model:

Installation

The recommended way to install this package is via PyPI:

pip install obj2mjcf

If you additionally install V-HACD 4.0, this tool will create a convex decomposition of the mesh to use as the collision geometry.

Usage

usage: obj2mjcf [-h] --obj_dir OBJ_DIR [--use_vhacd] [--save_mtl] [--save_mjcf] [--verbose]

optional arguments:
  -h, --help         show this help message and exit
  --obj_dir OBJ_DIR  Path to a directory containing obj files.
  --use_vhacd        Whether to create a convex decomposition for the collision geom.
  --save_mtl         Whether to save the mtl files.
  --save_mjcf        Whether to save an example MJCF file.
  --verbose          Whether to print verbose output.
