i don't know why that weird triangulation in the spines shows up in the render; hoping it won't be an issue in-game

Convert your quads to tris and see if it shows up in blender, if it does it's likely to show up in-game as well. Probably because your quad isn't actually flat so when its converted to triangles it has to choose somewhere to place the fold.
The easiest fix for this that I know of is just to take the quad with triangulation and smoothshade then separate it from the rest of the mesh, that way the shading still looks pretty much like its flat and you don't get any pesky triangulation.
