For the project to run, you’ll first need to install 2 plugins. Make sure to close the Unreal Editor before doing so. Use the NGC CLI to download these resources:

ngc registry resource download-version "nvidia/ace/ace-unreal-renderer-http-api-plugin:0.1.0"

ngc registry resource download-version "nvidia/ace/ace-unreal-renderer-stream-helper-plugin:0.1.0"

Then place these plugins in a folder named “Marketplace” under the Plugins-folder of the project (e.g. C:\<PATH_TO_YOUR_UNREAL_PROJECT>\Plugins\Marketplace). If the “Marketplace” and “Plugins” folders don’t exist, create them.

Note

Beware of nested folders when unzipping:

The plugins are written and built for Unreal Engine 5.3. If you are using a different version, you will need to build the plugins yourself. There is also a chance, that some interfaces changed, so you might need to adapt the code to the new interfaces.
