I see shadows scattered all over different tilesets, so it’s indeed hard to work with them. It also depends at which layer I put those shadows (ground level or above everything level).
I know James can do graphics. Can you or someone else create some good shadows?
In the REFMAP Buildings I still have room for 2 x 23 tiles. The tiles themselves are 32×32 pixels.
So if someone can make me maximum a 2 x 11 tileset, I can add them to ‘REFMAP Buildings’. That allows me to configure one of it on ground level, and one of it above everything.
If you look at ‘Inquisitor ground’, those tiles are ordered to support any combination (in the future I will use them for autotiling so you don’t have to pick them manually). Maybe the shadows should also be in this order? That would make them 2×7 tiles, and so would still leave room for 2×4 shadow tiles which are different, maybe such as the triangle tiles in the example above?
