• Removes the use of body view inside the asset classes by @Mayankm96 in https://github.com/isaac-sim/IsaacLab/pull/643
• Renames SimulationCfg.substeps to SimulationCfg.render_interval by @Dhoeller19 in https://github.com/isaac-sim/IsaacLab/pull/515

✈️ Migration Guide

Renaming of SimulationCfg.substeps

Previously, the users set both omni.isaac.lab.sim.SimulationCfg.dt and omni.isaac.lab.sim.SimulationCfg.substeps, which marked the physics insulation time-step and sub-steps, respectively. It was unclear whether sub-steps meant the number of integration steps inside the physics time-step dt or the number of physics steps inside a rendering step.

Since in the code base, the attribute was used as the latter, it has been renamed to render_interval for clarity.

Removal of Deprecated Attributes

As notified in previous releases, we removed the classes and attributes marked as deprecated. These are as follows:

• The mdp.add_body_mass method in the events. Please use the mdp.randomize_rigid_body_mass instead.
• The classes managers.RandomizationManager and managers.RandomizationTermCfg. Please use the managers.EventManager and managers.EventTermCfg classes instead.
• The following properties in omni.isaac.lab.sensors.FrameTransformerData:
  • target_rot_source --> target_quat_w
  • target_rot_w --> target_quat_source
  • source_rot_w --> source_quat_w
• The attribute body_physx_view from the omni.isaac.lab.assets.Articulation and omni.isaac.lab.assets.RigidObject classes. These caused confusion when used with the articulation view since the body names did not follow the same ordering.
