Rendering object that is partially obscured by another

Hello guys.

I work on a VR object and i am making object handles for moving, rotating and scaling.

Currenty i am using two cameras and i am rendering the object handles always on TOP for easier use (if object is scaled way too big and obscures the handles, for example)

I want to make the object handle partially transparent when is obscured by the object>
NOTE: For the object handle i am using Sprite Renderer, so it is not a texture on a mesh.


Is there any easy way to do this? as the project time i have left is not so much i cant spent too much time writing shaders ? Is there any shaders free to use to achieve this effect or any other approach that is achievable within few hours ?

thanks !

I think this might be helpfull :
