# Description

Previously, benchmark scripts were stopping the benchmark outside of the
global rank check and this occasionally causes issues on processes with
global ranks > 0. This change moves the call to be inside the if
statement such that it is only called on the rank 0 process.

# Description

This PR corrects the position of the method
`self._modify_action_space()` in the RSL-RL Wrapper, so that it is only
called after retrieving the dimensions of the environment, preventing
errors related to the use of uninitialized attributes when using
`clip_actions` in `RslRlVecEnvWrapper`.

Fixes the environment test failure for
Isaac-Stack-Cube-Franka-IK-Rel-Blueprint-v0. The env uses a custom image
observation term which tries to access an element in the recorder
manager. During env creation, the observation manager is initialized
before the recorder manager, thus causing an error in the observation
term. The custom image obs term has been updated to only try to access
the element in the recorder manager if it exists.

# Description

To support creation of managers before the simulation starts playing (as
needed by the event manager for USD randomizations), the MR in #2040
added a callback to resolve scene entities at runtime. However, certain
class-based manager terms can also not be initialized if the simulation
is not playing. Those terms may often rely on parameters that are only
available once simulation plays (for instance, joint position limits).

This MR moves the initializations of class-based manager terms to the
callback too.

Fixes #2136

# Description

Certain scene-level randomizations (such as randomizing the scale) must
happen before the simulation starts playing. To this end, the MR adds a
new event mode called "prestartup," which gets called right after the
scene design is complete and before the simulation is played.

Since the scene entities cannot be resolved before the simulation starts
playing (as we currently rely on PhysX to provide us with the joint/body
ordering), the MR adds a callback to resolve the scene entity
configurations separately once the simulation plays.

This MR replaces the prior implementation in #1165

# Description

Currently, the actions from the policy are directly applied to the
environment and also often fed back to the policy using the last action
as observation.

Doing this can lead to instability during training since applying a
large action can introduce a negative feedback loop.
More specifically, applying a very large action leads to a large
last_action observations, which often results in a large error in the
critic, which can lead to even larger actions being sampled in the
future.

This PR aims to fix this for RSL-RL library, by clipping the actions to
(large) hard limits before applying them to the environment. This
prohibits the actions from growing continuously and greatly improves
training stability.

Fixes #984, #1732, #1999

# Description

This PR adds an interactive demo script that runs inference on a trained
H1 rough terrain locomotion policy and allows selection of environments
through clicking on a robot and controlling it with keyboard inputs.

Additionally, a minor hyperparameter is updated in the SKRL training
config for slightly better policy behavior.

# Description

Sometimes users want to import a USD file which doesn't have any
collider meshes. This MR allows having such USD files in the terrain
importer for visualization purposes.

Additionally, the MR removes the storage of warp and tri-mesh based
meshes inside the class. These are stored into the USD and are read
directly from there whenever needed. Their intended use-case for having
them inside the terrain class is not needed.

# Description

There was a lot of code duplication happening inside the `Articulation`
class. This MR takes a step towards untangling some of the confusion
that gets caused by default and non-default data attributes inside the
class.

The MR includes the following changes:

* Removes operations where we set the data to "torch.zeros" and in the
next function assign them the value from PhysX. This made the code
bulkier and complex for no reason.
* Adds docstring clarifications to make it clear what is what. The
default values are now whatever the user configures from their
configuration of the articulation class.
* Updates the `soft_joint_pos_limits` when the user writes the joint pos
limits to the simulator.
* Renames parameters for a consistent nomenclature:
* ``joint_velocity_limits`` → ``joint_vel_limits`` (to match attribute
``joint_vel`` and ``joint_vel_limits``)
* ``joint_limits`` → ``joint_pos_limits`` (to match attribute
``joint_pos`` and ``soft_joint_pos_limits``)
  * ``default_joint_limits`` → ``default_joint_pos_limits``
* ``write_joint_limits_to_sim`` → ``write_joint_position_limit_to_sim``
  * ``joint_friction`` → ``joint_friction_coeff``
  * ``default_joint_friction`` → ``default_joint_friction_coeff``
* ``write_joint_friction_to_sim`` →
``write_joint_friction_coefficient_to_sim``
  * ``fixed_tendon_limit`` → ``fixed_tendon_pos_limits``
  * ``default_fixed_tendon_limit`` → ``default_fixed_tendon_pos_limits``
  * ``set_fixed_tendon_limit`` → ``set_fixed_tendon_position_limit``

# Description

The RayCasterCamera test checks that the vertical aperture should match
the value specified in the config. However, the config's vertical
aperture is not set. This PR updates the test to check against the
default computed vertical aperture value instead.

# Description

In the Isaac Sim 4.5 release, ``TiledCamera`` produces incorrect
semantic and instance segmentation outputs when using instanceable
assets. With scene instancing enabled, only the first tile generates
correct outputs while other tiles produces blank data. This change
introduces a workaround for the issue by disabling instancing on the
assets when semantic segmentation and instance segmentation data is
required from ``TiledCamera``. This workaround introduces a small
slowdown in performance, but it's not significant when running with
smaller scenes, which is normally the case when using rendering.

Fixes #1946

# Description

This is a documentation only change that adds instructions for updating
pytorch to the nightly build when running with 50 series GPUs to avoid
CUDA issues. In addition, we added the v2.0.1 release notes and an extra
note for the v2.0.0 release for a breaking change in the semantic and
instance segmentation outputs when using tiled cameras.

Fixes #1888
