I have seams in my models. I created a 500x500x50 cube in blender for use as a building block and set everything to smooth shading with an edgesplit at 89 degrees so the edges would be sharp and exported it from blender to .fbx with face smoothing turned on and when I import it I have UE calculate the normals (since blender doesnt have a “tangents” option i dont think,only face normals) when I put my blocks together with no material or even with a seamless texture applied to the whole object I get visible seams. I’ve tried it in my main project with skydome etc. and in a blank project with nothing but a point light. Check out the pics. Any ideas? Edit: I also did recalculate lighting.
