True but I added the support loops to try and get rid of the errors, I get the same results without the support loops. On the original model, the side table, I want to avoid adding support loops (on the legs and frame) as it will almost triple the vertex count.
Ok, I finally worked it out. The problem was that I had the smoothing of the low res mesh set to 0 degrees. Apparently because of that the angle was too big for the normal map to handle. I had two versions of my side table, the original one and one with the sharp edges beveled. With the original one having a smoothing…
