Has anyone encountered the issue of inverted meshes generated from pose? #202

Open zjutcaicai opened 1 year ago

zjutcaicai commented 1 year ago

When I generate meshes from the pose in the pkl file,the entire person is upside down.The overall y and z axes are reversed. How can I handle the pose to make it normal? I need to retain the pose for some reasons. thank you.

If you are using the following to generate the mesh from the pose in the pkl file, you can comment the 2nd line that uses the rotation_matrix. 

out_mesh = trimesh.Trimesh(vertices, body_model.faces, process=False)
        rot = trimesh.transformations.rotation_matrix(
            np.radians(180), [1, 0, 0])
        out_mesh.apply_transform(rot)
        out_mesh.export(mesh_fn)

Thanks!I already know this code. I hope to rotate the pose instead of the final obj. This is very difficult for me, because it seems to involve Euler angles
