How do i hollow out a sphere in blender

If I’m understanding correctly there are a couple of ways you can do that.

Either with boolean :

Blender Tutorial - Boolean Modifier (3D Modeling Essentials)

or choose face mode

choose the faces you want to delete

and press x and choose faces

Whit this method you will have to extrued the faces on the inside or use double sided faces on roblox otherwise they will be transparent

i actually inverted the normals of the faces so i got the effect i wanted, thank you!
