Notes#

The Asset Browser is in Beta and still have some limitations. Here are some known issues:

  • When searching, the Asset Browser will search for assets in the current category only. If you want to search for assets in all the categories, make sure click on the All category before typing in the search bar.

  • Try not to click on other categories while searching, as it will reset the search category and confuse the search results.

  • The Asset Browser is currently set to display only USD files. If you wish to see other file types, such as image or text files, you can switch to the Content Browser if you have Omniverse Nucleus installed. Or run the following snippet in the Script Editor to update the Asset Browser settings. Toggle line 6 and 7 depending on your preference. Consult Modify Carb Settings for more permanent ways to changing Carb settings.

  • For non-USD assets, the only available way to view them is to download it to your local computer for now. Use the Download button provided in the panel, or right click on the thumbnail to download.

11omni.kit.app.get_app().get_extension_manager().set_extension_enabled_immediate("isaacsim.asset.browser",False)
12omni.kit.app.get_app().get_extension_manager().set_extension_enabled_immediate("isaacsim.asset.browser",True)

Note

The assets are cached for faster loading, so when you change the settings and restart the extension, the browser will still show the cached assets at first. Clicking on each of the categories will trigger the browser to refresh, show the updated assets, and update the cache accordingly.
