So how to hide front-facing polygons while rendering, and show back-facing ones?
Recalculate the normals to the inside so that the front facing polygons are facing backwards.
That will mess up physics simulation.
As you will mess up your Phys Sim you could try camera clipping.
Set you start to be the centre of your object then adjust to cull further
into object or further out.
Hope this Helps?
But blender devs should add option to do front-face culling as well.
You should probably take your setup for backface culling and reverse it. I would use the node based approach.
