Bad shading on icosphere set to smooth I used an icosphere to model a part of a building, I have autosmooth enabled with custom sharp edges but I can't fix the bad shading. In Eevee it looks perfect, but in cycles I get weird shading that follows the edges of the tris instead of working like it should. Is it a problem from lighting (I'm using an hdri), from normals or should I just avoid using triangles and use quads? I already merged by distance so there aren't any overlapping vertices and all the normals are facing the right directions.
Terminator effect, only way to make it work is using more geometry.
