Is there a way to blend with two 3d object without the background color

Every scene has a background in threejs. But now , I just want to create a blending effect between two 3d object and get ride of blending the background color . Is that possible to achieve the blending effect ?

I don’t think this statement is correct. Scene.background is null by default. If you don’t specify a color or texture, no background is rendered. This can easily be demonstrated by applying alpha: true when creating the instance of WebGLRenderer. You will then see the background color of the HTML’s body element.
