Transparent without backside ?

[clemense]

Hey everyone,
I'm currently working on a scene where objects in a cloner move along a spline towards the camera.
I'm controlling the transparency of the objects that are getting closer to the camera via plain effector so that other objects behind them don't get covered.
Unfortunately the transparency in cinema unveils the backside of the "close to camera" objects as well. This complicates the legibility of the scene.
I was wondering if there is a way to make objects transparent without showing their backside but still seeing objects behind them. Kinda like it would look in photoshop when you have 2 layers with objects covering each other
and lower the opacity of the upper one. I'm very thankful for any hints, thx in advance
