A Blender add-on for building tile based low-poly scenes with paint/map editor like tools · By Jeiel Aranal
Yeah, as what the title says :). how big can my tiled world be? As big as Blender allows it? I'm thinking of creating backgrounds with this.
Yep, it would be the limits of Blender and the 3D engine if you're exporting to somewhere else. There may be performance issues with higher polycounts since Sprytile uses raycasting but I haven't really put it through a stress test.
