I'd like to combine multiple 2D meshes into one, then use as a sprite mask....

So if you could ignore what are clearly WIP visuals here, essentially what I'm doing here is procedurally generating more interesting ground / soil colors for my game.

https://store.steampowered.com/app/1826120/Hive_Defender is what it looked like before with prototype visuals.

Right now I'm blending all of the tiles together via alpha channels and perlin noise sprites, which works well -- but there's all this little bit hanging off the sides.



I have about 150+ 2D meshes in the shape of hexagons which use 6 triangles (7 points) each.

I'd like to somehow combine all of these meshes together into some kind of super mesh, and then use that mesh as a sprite mask such that only sprites within this big mesh are displayed.

I then intend to layer on ground texture, cracks, pebbles, etc... using the same method.

Any idea how to actually do this? I've been a few hours browsing the web, but I think there's probably a very specific term for what I'm trying to do but I can't find it.

 

You're welcome to check out my MakeGeo project for how to manipulate geometry in code.

If these are sprites however, I'm not sure there is any official way to even get the geometry.

Yeah the noise textures are sprites.

Maybe I can find a method to convert a mesh into a sprite, then combine all the smaller meshes into one big mesh, then turn that giant mesh into a sprite, then use that as a sprite mask.
