Hi, update: i'm now using another concept. (i think thats the one you recommended at the beginning of the thread)
instead of my original indexlist: 0, 1, 4, 2, 5, 3, 4, 0 which prevents me from assigning more than one normal per vertex, i'm using index swaps to "(re)visit" a vertex more than one time. this allows me to assign more than one normal per vertex without violating the triangle_strip rules. new indexlist: 0, 1, 4, 1, 4, 2, 5, 2, 5, 3, 5, 3, 4, 0 normalslist: W, W, W, S, S, S, S, E, E, E, N, N, N, N normals[]: {North, East, South, West} Thank you!
