How to cut-out parts of a sphere?

[NeilAgg]

I searched but could not find a tutorial on this. I assume there has to be one.

I am trying to create a sphere with cut-outs in it so I can see what is inside it.
I want there to be an outer sphere (a shell) which is solid but has portions removed so the user can see portions of a glowing sphere inside it.

Can someone point me to a tutorial on this?

There is no tutorial on this ( I would bet ).

You need Blender

I started doing a short tutorial about it, but it’s a bit of a fiddle if you’re not up to speed.

You basically have to

1. Make a sphere
2. Use a solidify modifier to give it depth
3. Cut the shape out
4. Assign a different material to the inside and outside
5. Import to Unreal
6. Put the materials on the mesh

Oh… Interesting. I did not realize I had to do that outside the engine. I have used Blender. I will play with it.

I doesn’t look much cop yet…

You can do some of it with the geometry mode, but not all of it…

[NeilAgg]

That is exactly what I want. Did you do that in Blender?

[ClockworkOcean]

Not this?

Turns out that having a hidden emissive mesh inside look better.

Turns out that having a hidden emissive mesh inside look better.

That is cool, but I don’t want to see inside the object. I think your first example is exactly what I want.

Ok that’s two materials then…

In Blender, make a sphere and give it thickness with a solidify modifier

and apply.

Use a boolean to cut out the port

Then go into face mode, and assign one material to the outside

and another to the inside.

Then just export as FBX and import to the engine. You can do all of it except the sphere thickness in geometry mode actually.

PS: In fact, I just figured out how to do a ‘thick sphere’ in the engine, but it’s more of a hassle. ( You have to make two, invert the normals on one, and merge them ).
