How to make one clear object invisible inside of another clear object? So for my animation, I have water draining out of a clear sphere. Unfortunately, through the sphere, the flow of water is visible when I don't want it to be. I only want the flow to be visible when it exits the bottom of the sphere.  



I still want the sphere to be translucent to the point where the viewer can see over to the other side, I just don't want to hide the part of the inflow inside the clear sphere.

Does anyone know a way of using a translucent object to hide a section of another object while keeping the former object see-through???

I'm trying to avoid masking it out in post.

A link to my project can be found down below.
There is a trick that worked very well for me:

You can make the object "invisible" inside of the clear sphere by adding another sphere just slightly smaller inside of it, adding a Boolean modifier to both the water inside the sphere, and itself. Then set the Boolean sphere to fully transparent so you do not see it. Now the water inside of the sphere should have disappeared. Make sure you do not apply the modifier at all, as that would apply it to the vertices, and change the simulation.
