Usage

Reading Mesh

Command Line

python3 RBXMesh.py ExampleMesh.mesh

Python

from RBXMesh import FileMeshData, read_mesh_data

with open("ExampleMesh.mesh", "rb") as f: 
    meshBytes : bytearray = f.read()

meshData : FileMeshData = read_mesh_data( meshBytes )

Exporting Mesh

Command Line

Supports exports in Mesh V2 and V3

python3 RBXMesh.py ExampleMesh.mesh 2.0

python3 RBXMesh.py ExampleMesh.mesh 3.0

Python

from RBXMesh import FileMeshData, read_mesh_data, export_mesh_v2, export_mesh_v3

meshData : FileMeshData = read_mesh_data( meshBytes )

with open("ExportedMesh.mesh.v2", "wb") as f:
    f.write( export_mesh_v2(meshData) )
with open("ExportedMesh.mesh.v3", "wb") as f:
    f.write( export_mesh_v3(meshData) )
