How to see the inside of a solid. (VC Orb)

[Akiritto]

Hello,

I'm using VC Orb Plugin to make a sphere surrounded by animated rings(1), for them I use another sphere with a masked solid(2) as the texture that repeats on the Y-axis.

My problem is that the inside of the sphere isn't rendered(3), have you any ideas on how to do it?

PS sorry for my bad English, hope images make it clear.

Thank you!
