I wanted to make an underground microdungeon with a realistic ore seam instead of little ore blotches, but I couldn't find any type of ore placeable in the tiled editor. Is it even possible?
Sorry, I did a bunch of looking, but the closest things I found were the files "distributions.config" and "oredistributions.configfunctions" in the folder "/biomes". But then, those are for biomes, and not even for dungeons. One would think there would be some way to place ores non-randomly... I suppose, potentially, you could make your own tile type that drops a specific ore when mined.
It uses modifiers, you can copy paste the box easily from the apex test facility dungeon. Modifiers can be found in assets/tiles/mods/- then enter into the "mods" box the desired modifier: (moss is the current one). this is also how to paint blocks, if you look at the ship dungeons, and add grass etc.
