There's a lot of things to love and try to understand about RimWorld but the thing that's really got me thinking lately is the tile map. Now there are a few posts around about tile maps but I haven't found anything that really sheds any light so if anyone can I'd be very greatful. Some things I don't understand/want to know: Rimworld's tiles don't have a single texture that repeats on every tile of the same type. They appear to use larger textures that are spread accross multiple tiles (if not all tiles of the same type in the map). How is this achieved? Rimworld's tile textures blend and merge together. They have a soft transition where dirt and stone meet, for example. Is it using special textures that cover every possible transition or some other technique? There is no tearing/seams between the tiles in the tile map. RimWorld still suffers from this a little with it's wall tiles but the floor/ground tiles don't have any of this. Is this because of the previous thing? Personally I've implemented a very simple tile map. A custom mesh with 4 verts and 2 tris per tile, using the UVs to select various tiles from my tile atlas texture. This works but has issues with seams unless the tile images in the atlas are padded and doesn't address the blurring/merging or the textures spread across multiple tiles. I'm here asking for insight as I really don't know how to move forward on this so any help would be appreciated. Thanks.
