Kit 107 composer fails to build with isaacsim.core.nodes

[stephen113]

In my kit 106.3 composer, I have been using: these dependencies:

“isaacsim.core.nodes” = {}
“isaacsim.code_editor.vscode” = {}

When I try to create a new composer from template with these dependencies, I get this error:

2025-04-18 20:48:18 [1,574ms] [Error] [omni.ext.plugin] Failed to resolve extension dependencies. Failure hints:

Yes that makes sense. This is not designed to work this way. Isaac Sim and the Kit App Templates are totally different. The two do not work well together. You “may” have some luck if you use the exact same version of kit. Isaac Sim 4.5 is based on kit 106.5.0 You can try on Kit KAT 106.5.0 But we do not recommend this approach. Isaac Sim is a different animal.

I’m surprised, I didn’t realize that. Can Isaac import omni dependencies?

I think I misspoke, my kit app is 106.5.

Can Isaac Sim import new extensions? Yes. You can do it from the normal Extension Manager. Or you add them to your kit file. But they would have to be specifically compatible with Isaac Sim. The right extension, the right version.
