Using render_smpl to visualize pw3d_test.npz

[SiriusNEO]

I try to use API render_smpl to visualize the mesh generated by the smpl model stored in pw3d_test.npz.
My method is:

• Get cam_params from the data
• Use get_KRT method to get the intrinsic and extrinsic matrices K, R, T
• Visualize it by calling render_smpl and passing K, R, T to it.

Here is my call:

render_smpl(
            poses=pred_pose,
            betas=pred_beta,
            K=K,
            R=R,
            T=T,
            projection='perspective',
            convention='opencv',
            in_ndc=False,
            output_path=pic_path,
            resolution=resolution,
            body_model_config=body_model_config,
            overwrite=True,
            plot_kps=True,
            frame_list=["tmp.png"]
        )

But my result is not so good:

What is the problem?
