Yeah I didn’t quite fix it, but I found that making chunks with a size of 64^3 or 128^3 give me perfect results, but 256^3 gives me weird sine wave artifacts. I still have zero idea about texturing though, every example I’ve seen online does texturing by manually feeding the verts in idecies to a vertex factory. All of that completely bypasses the class Unreal has given us (which is nice and easy to use) and just makes things complicated. For now i’m just using vertex colors with the MaterialDensityPair.
