I am trying to make a perfect subdivision modifier dome shape (i.e. no surface distortion with subd enabled) that has 12 vertices at the bottom (i.e. where the dome connects to another shape I am modelling).
As you know the sphere given by blender doesn't work with subd, as the geometry at the top leads to distortions when combined with subdiv modifier.
Thats why I modelled a sphere using the following method (cube with subd that is adjusted with different method): https://www.youtube.com/watch?v=aRSVYFrRWeU
I only applied Subdiv lvl 1 and then cut the sphere in half. However that gives me 16 vertices at the bottom.
I need 12 (because the dome has to be connected to a shape that has only 12 vertices as connection points).
Is there a way to make a perfect subdiv dome with 12 vertices at the bottom?
