How Isaac Sim and Unity work together

I’m currently working on a project that links Isaac SDK and Unity.
I am proceeding with reference to the following document, but I feel that the information is outdated.
So, I wonder if the development of Isaac SDK has ended?
Also, if development is finished, can you tell me about the latest ways to get Isaac Sim and Unity to work together?
It would be very helpful if you could provide us with specific steps for collaboration and URLs that may be helpful.

Hi @ntrkt

Since 2020, Isaac Sim is not based anymore in Unity… but in Omniverse.
For building virtual robotic worlds and experiments I recommend you to fully migrate your project to Omniverse Isaac Sim

However, if you want to connect Unity with Isaac Sim (for OpenUSD data I/O pipelines) you can rely on the Unity Connector
