You can set up 1st person view in the map note<mv3d>camera(,90,dist:0)</mv3d>It's already possible to assign custom textures to tiles. For example, to assign image.png to tile c,0,0 in the tileset note
<mv3d>c,0,0:texture(image.png)</mv3d>
Where do I store my textures to make them visible when using this tag?
