While this asset looks amazing, the demo scene is almost impossible to use.
Most of the world geometry is joined to the mesh "Tomato.016" and they are over 1800+ materials. Godot has a limit of 256 materials per mesh. Please use the same material for the same color instead of making a new one each time, and name them individually, every material being 'Material.#' makes it impossible for me to merge unless I do it manually.
I spent 5 hours working on this to get it in game for my gamejam project and gave up.
