I have been designing easter eggs to be 3D printed with pattern textures on them and I have stumbled across an issue when adding a texture to the egg model. As you can see there are a lot of artifacts and pinching on the rounded corners. Is this due to the mesh not being uniform with quads?

Thank you very much in advance for your assistance.

    hello, it is rather a topology issue, please show the topology in wireframe mode, you probably need to clean that in Edit mode, see here: https://blender.stackexchange.com/questions/70810/how-to-avoid-the-wrinkle-at-the-poles-of-the-uv-sphere ... or do it in Sculpt mode as it looks like your topology is high-poly – moonboots Apr 01 '21 at 09:23
  • @moonboots Thank you very much, I appreciate this. – Tidus Apr 01 '21 at 10:08
  • in Sculpt mode you could enable Dyntopo and use the Smooth brush, but it looks like you've sculpted a texture? So maybe use it for the pole as well? – moonboots Apr 01 '21 at 10:09
  • @moonboots This was done through the Displace modifier, adding a texture through there. Smooth brush causes it to crash Blender unfortunately. – Tidus Apr 01 '21 at 10:14
  • oh ok so you should improve the pole topology instead – moonboots Apr 01 '21 at 10:15
  • @moonboots I shall give it a shot, thank you again for the link and advice. – Tidus Apr 01 '21 at 10:16

Intro

Spheres can be generated with multiple approaches. Every approach has its down- and upsides. It depends what you are trying to achieve.

Sphere from Primitive Sphere

The problem here is the vertex on top. enter image description here

After applying subdivision you will get some interesting topology, looks cool but it's maybe not what you are looking for. I call it the tomato topology.

enter image description here

Sphere from Icosphere

Subdivision can be done while you enter parameters for the icosphere. There will not be a tomato topology. But there is a catch, you can't do loopcuts nor loopselections. Also it can cause problems if you use it with boolean modifier. Short: The triangle faces are causing issues down the line.

Sphere from Cube

With this approach you will be able to have quad topology without tomatos. Loop selection is also possible.
