A building piece I keep wanting is a path or road, in order to liven up scenes created on the island. It would be a mostly flat square that could still interact with beans similar to the flowers. In order to handle directions, a horizontally and vertically repeatable dirt/cobblestone/… texture would probably be ideal.
We did actually have an idea to make a road structure that would sort of act as a conveyor belt!
But yeah, we do have some ideas for buildings like roads and trees to liven up the islands that people can make! We do need to think about the technical ways that it would interact though, like buildings roads between 2 tiles that have the road structure on them - or just that a road is a tiled texture, which is what you're saying, if I'm not mistaken!
Thank you for the suggestion!
