NEW UPDATED VERSION AVAILABLE! Scroll down a few posts.
I submitted a new user interface to the marketplace. It is quite flexible and would suite anyone who doesn’t have his own user interface or doesn’t know how to build one. It’s 100% blueprint. Everything can be entered into the floor plan blueprint that you place in your level. No blueprint knowledge is required. It works in 4.19 and 4.20 at the moment. Here is a link.
Or check out a page with a bit more detailed info about it than on the marketplace
Finally here is a user guide how to implement it to a project
Please let me know if you have any further questions about it.
