How can I remove the background image from the new rooms I create? I want a simple black background for now. Thanks

Is it currently possible to add your own background images for rooms etc or is it a planned feature?

Last news post was Jan this year showing off some new Map features, did this get updated into the engine? i haven't used it in a long while. But have been waiting until its nearly features complete etc..

What does this do exactly? when toggled on i see a large red retangle square in middle of screen and a small grey box to left of it and another above the main rectangle square.

Will it be possible in the future to host a coop game on your own machine rather than a dedicated server? friends connect to your machine. I know this can be tricky, back in the minecraft days getting friends to connect to your game was hairpulling. Still...
