I’m trying to add the following plugin to Unreal Engine 5.6
But pressing the plus while in the fab window in a project doesn’t add the plugin, and tutorials reference the fab tab in the epic games launcher which no longer exists.
If you add it in the Epic Launcher, there should be a “add to project” option there.
On top of the comment above, you could also try downloading the asset manually from the website, then put the plugin in the Plugins/ directory in your project.
It’s not ideal but might at least be a temporary solution to this problem.
