Hi Team!
I created a custom node in Isaac simulator following these instructions
https://docs.omniverse.nvidia.com/prod_extensions/prod_extensions/ext_omnigraph/deforming_text_create_node.html
This node is available in the search bar for instantiation and interaction with other components.
But after reloading the simulator, custom nodes disappear in the search bar and cannot be reused.
I solve this problem by doing the following steps:
remove directory “omni.new.extension”
click “Populate Extension” button
copy source code to destination folder
