Sorry, back when I answered, I edited the CMS but it seems saving failed. I've fixed that now.
As for an "installer", I'm not quite sur3 what you are refering to. We can't publish our plugin on the Epic asset store as they don't allow our license. As with other plugins, you thus have to either copy the files to your project (which is the better option) or to the engine installation. I don't see a way around that. If you know of one, please link to the respective documentation describing the process. I'm coming up empty in the UE docs.
