Hello, I have tested it, and it appears to be correct in the documentation. qpos[0] Is the x coordinate qpos[1] is the y coordinate ```py import gymnasium import numpy as...

Hey, @onnoeberhard sorry for taking a while to respond, I had to study how Quaternions work :-) all material on quaternions I could find denote them as $a + bi...

Here is the relevant documentation page in the latest version of MuJoCo Library (3.1.3) https://mujoco.readthedocs.io/en/3.1.3/programming/simulation.html#data-layout-and-buffer-allocation you are correct, the order is `(w, x, y, z)` The affected environment's documentation is...

see https://github.com/Farama-Foundation/Gymnasium/issues/842, this will be worked on after 1.0 release

Observation is already returned by step()

The problem with your suggestion is that it is not JITable. ```py def mjx_get_physics_state_put_version(self, mjx_data: mjx._src.types.Data) -> np.ndarray: """Version based on @btaba suggestion.""" data = mujoco.MjData(self.model) mjx.device_get_into(data, mjx_data) #data =...

@RedTachyon check the above comment Thanks

Assuming the Environment which used `gymnasium==0.29` is not broken from the `gymansium==1.0` update, it should just work without any additional compatibility work in SB3

i tested this: (from https://stable-baselines3.readthedocs.io/en/master/guide/examples.html#record-a-video) ```py import gymnasium as gym from stable_baselines3.common.vec_env import VecVideoRecorder, DummyVecEnv env_id = "CartPole-v1" video_folder = "logs/videos/" video_length = 100 vec_env = DummyVecEnv([lambda: gym.make(env_id, render_mode="rgb_array")]) obs...

Does the issue persist with `gymnasium==1.0.0a1`? (note: `metaworld` may break though)
