Currently it is released and tested on UE 4.15. If you or anybody else would relay like to test it, but needs a different version pleas tell us, we should probably be able to provide. (Also we have not tested this binary with other versions, it might be compatible as is)
We are currently interested mostly in receiving feedback from you guys! Than will see what are the most wanted features/enhancements and try to plan our relese schedule based on that.
For now, we know that there is a great interest for the Open Street Map integration, and we will be working on it.
So, please test usability of the plugin and then toss some comment or suggestion. We will be polishing things out in the following months going towards beta and full release.
@Nocturness Maybe I misunderstood - I answered regarding the release of fully featured plugin. But are you interested in buying (or downloading alpha version for testing) of this plugin on the marketplace specifically? If so, why? And would you consider getting it from our website or other place.
