Following the instructions in Cesium for Omniverse Quickstart – Cesium , the Cesium extension is not found in the NVIDIA or in the Third Party lists. This is a fresh install of Isaac Sim 6.0.0 on Ubuntu.
Hi Ted. Thanks for writing!
Isaac Sim 6.0.0 uses Kit 110.1.1. The current published extension (v0.28.0) was built for Kit 109. Kit 110 support has been added and will be included in the next release. This is usually the first or second business day of each month. Then it should appear in the Extension Manager. You can track the issue at cesium-omniverse #770.
Please let us know if you encounter any issues.
Thanks!
