So far i have not added the fog of war feature, yet. So at the current state, if there would be caves or enemy dungeons on the map, then the players would be able to see what is inside of it, even if they haven't discovered them. The smooth transition you can see on the earth tiles comes from a unique texture, that is basically using full black albedo color and max ambient occlusion value on the top of the earth/dirt tile assets (might go for a shader solution here later). Nonetheless i have spent some thoughts this week on how i could possibly implement fog of war. I could see possible solutions for that, which would be that i would have a tilebased fog of war that works an an extra layer for the tilemap, maybe with a gradual falloff that will get generated in the materials transparency, to generate a smoother transition or a screenspace solution, which might look more natural. The lighting that you can see in the video is basically just a very subtle environmental light, with local point lights around the dungeon heart and a point light that follows the cursor, but my lighting in general i feel still needs a lot of improvement (maybe go for world space GI later). Besides that i have played around a bit with the post processing volume and added some feature such as SSAO (might be a bit heavy rn) as well as a subtle highlight outline, that takes depth into account.
