Is there a way to render parts of an object on one side of the plane?

Hi everyone. I just recently started messing around in Unreal Engine 4 and I was wondering if it was possible to check for collisions in a material editor. What I’m trying to do is use a plane to check for these collisions; pixels that are in front of the plane will be rendered. Pixels behind it will be discarded. However, since it seems that it is a lot of setup to have Unreal use a custom pixel shader (and custom nodes in a material editor are essentially HLSL code) I’ve been looking into the material editor to try to have the same result. As of right now I’m a little stuck. Anyone have any ideas as to how I might be able to accomplish this?
