So I’ve been trying to get things working for procedural map generation. My end goal is pretty simple. A top down game with a tile system (or hexagon?) I just want to use 4 or 5 textures to blend together and basically have a grid layout like this but having some height information to each tile https://www.youtube.com/watch?v=nGA7lAumQwU
my game and how it will play: tile based, top down shoot 'em up http://i.imgur.com/utt4x9W.png
How I’ve been trying currently is using a square 1 polygon tile and then applying a material with color, normal, height etc. that blends between the textures. So grass and dirt, etc. The problem with this method is that collision cannot be generated based on a height map.
What would be some workarounds for that? Or would there be an entirely better way to go about it? Because how I’m doing it now is a grid block system and it’s quite hard to get natural blending between each square tile.
Would I want to try out landscapes? Something like this https://www.youtube.com/watch?v=39uMosogVog would be perfect since it generates the colission but I have no idea where to start to get something like it
