THREE.JS: View geometry when inside a grid

Question

When entering a geometry, such as a sphere of a sphere, it acts as if the geometry does not exist. Color and texture are visible from the outside. But as soon as I zoom in on the grid, the properties disappear.

How can I make the color and texture of the mesh visible inside the mesh?

Answer 1

mesh.material.side = THREE.DoubleSide; 

or

 mesh.material.side = THREE.BackSide;
