Isaac Sim 4.5 is now available.
The 4.5 release offers a number of significant changes, including the following:
- Renaming Extensions in Isaac Sim: With the release of Isaac Sim 4.5, extensions have been renamed and divided to enhance modularity, facilitating end-users in building custom applications using these extensions, including Isaac Lab. Users should ensure their code is updated to reflect the new extension names. Learn more.
- A reference application template: Isaac Sim has been redesigned as a customizable reference application. A minimal template for faster startup and a full template with complete functionality along with all dependencies. Additionally, users can take advantage of templates designed specifically for Synthetic Data Generation (SDG) and Software-in-Loop (SIL).
- Improved URDF import and setup: User Interface has been simplified to provide a more streamlined process and align with how other formats are imported, making simulations more stable.
- Improved physics simulation and modeling: Define and configure various joint types between robot components, setting parameters like stiffness and damping to fine-tune joint behavior.
- New joint visualization tool: Enables you to inspect the physics properties of selected prims, including their position, rotation, linear and angular velocities, and accelerations.
NOTE: With significant changes to renaming and restructuring, users should ensure that the existing code uses the new extension names.
