# How to combine multiple hemispheres into a single smooth mesh properly?

I am making an object which is made by combining one big hemisphere and four small hemispheres. Here is what I've done:

As you can see, one of the small hemispheres merges well with the big hemispheres while one merges not too properly.

Here is the mesh: This is the post I followed to make the object.

I made three spheres (one large sphere and two small spheres) first, follow the instructions to combine them, cut the upper half of the object and apply a mirror modifier.

However, when I tried to use Damped Track modifier on the second small sphere, the modifier align them in a way which the first small sphere overlaps with the second one. I think this is because I set the Damped Track Contraints to be Z for both small sphere, but if I set it to be other directions, the mesh will become what I've made above, which the second sphere cannot merge well with the big sphere.

• did you use a boolean operation? Commented Feb 6, 2018 at 18:22
• Yes, I used the boolean modifier to combine the spheres together. Commented Feb 6, 2018 at 19:06
• You will probably want to go with topology similar to this: imgur.com/kDLn4Uy It's 100% quad topology. I have used several different methods to achieve this and making an answer from it would be huge. Commented Feb 6, 2018 at 20:18
• I can make an overview of this particular creation and point you in the right direction. There are tutorials on every technique I've used there. Commented Feb 6, 2018 at 22:03
• also in the picture above, it looks like the small sphere centers are not aligned exactly with the center of the big one... or the section in half was not done exactly at the center. That leaves a lot of small faces to fill up. Making sure the objects are well positioned (snapping or manually entering coordinates) before boolean and bisecting would probably help.
