Solutions for a tile-based game on a polyhedron

Hello, I am making a tile-based game. Instead of using a flat tiling I want to make each face of a goldberg polyhedron a tile. I am having some technical difficulties regarding producing different configurations between games and change textures/tile-types at runtime. There seem to be a few possible solutions.

1. Polyhedron is a single object with one mesh, a texture atlas is generated procedurally and modified at runtime to change individual tile's textures. At the moment I have not found a way to do this, though I may experiment to see if this is possible.

2. Polyhedron is a single object but each face/tile is a submesh, allowing me to change textures at runtime. This is what I'm currently working with but I'm reading in some places that sub-meshes produce massive overhead, if anyone has insight on this that would be great. I am also having some issue regarding the positions of sub-meshes rekltive to their colliers but I think I can figure this out.

3. Each tile is a separate object, generated and arranged into the polyhedron at runtime. This seems like a needlessly complex solution but also like the one Unity is most suited for. I'd rather not have to figure out the math involved in constructing a goldberg polyhedron procedurally but I will if I have to.

Have any of you had similar dilemmas? What do you recommend? What do you know about the overhead of sub-meshes and modification of images/texture atlases at runtime?

Thank you for your time and help!

Edit: I apologize if I have posted this in the wrong sub-forum; I'm new.

 

Hi unity_zjCgQ21xcO2QTQ,
I'm facing the same problems as you.
Did you find a good solution to this problem?
Thanks!

 

I'm also interested in this solution. Did you ever achieve any success?

 

You are best to have multiple mesh objects, as the hex map also contains pentagons. If you did have the maths to produce this shape procedurally then you’d have no problem talking about specific faces. But the main problem is talking to specific faces. Which indicates to me that it probably would be easier due to the irregular pattern to be dealing with faces as individual objects.
