What you are asking is not exactly my area of expertise, but I’ll try to help you as best I can. If you want to use a polyhedric base mesh and create a sphere out of multiple arranged meshes, you could do it the same way I do it with a flat grid. I use some pretty basic math to calculate the position of each tile. Basically I multiply the X index of an array item by the X width of a tile to set its X location and multiply the Y index with the Y length of a tile to set its Y location (UE4 does not support 2D arrays so I fake this with a 1D array which makes it a bit more complicated). Hexagonal grid are a tiny bit more complicated, mostly because each row needs to be offset by half a tile width. You could do the same thing, the only thing being different is the formula you use for calculating the location and rotation of each tile in 3D space. The formula for this is more complicated, of course, but the concept is the same.

As noted earlier you would need to rewrite a few other things to get this working properly with the toolkit once you’ve got the meshes aligned properly. How to determine which tile index can be found at what location vector is one of these (you would have to do something similar to what you do when setting the location of each tile, just in reverse). Setting up which tiles share edges with other tiles (can be moved between) is something you would also need to do. To achieve this you would need to modify the Add Viewport Terrain to Arrays function in BP_GridManager. You would also need to change how visibility is calculated, as the current solution has some in-built assumptions about the structure of the grid. There are surely other things that also need to be changed (setting the rotation of units while moving comes to mind. This one should be simple, though), but these are the main obstacles I can think of.

Like I said, this is no small task, but it is achievable. I’ll be looking forward to seeing your progress. Feel free to post questions in this thread at any time.

Thank you - I’m going to do a bit more research. I’ll get back to you when I’ve made some progress!
