Question Nested transparent spheres - Can't visible the core

Hi all,

I'm trying to create layered spheres around a cube. Normally it should be transparent for each layer, but as the layers increase, the cube is not visible. How do I ensure the transparency of each layer equally? I just want the layers to be clearly visible but at the same time, I want to increase the visibility of the centre.

The button you see in the picture adds a layer each time and the central cube loses its visibility a little more each time.

Thanks.

 

If you make the spheres inside-out, then it would look about the same, but the cube would be perfectly visible.

Also, normally transparent objects render after opaque, but I think you can change when it renders in the material, so you might be able to set the cube's material to render later in the queue. Then the cube will render in front of the spheres.
