UE 5 - Glass (translucency) and alpha problem

Good morning/afternoon/evening

We have a question regarding the behaviour of alpha and translucency in UE5.

We are working on a project with SceneCapture2dComponent through which we capture an image of an object + a glass (see attachments).

Image captured:

We remove the background from this image so that only the object can be seen, and that’s where the problem comes in, because as it is a glass and a solid, all the background behind the glass also disappears, so the glass can no longer be seen.

Image without the background (here we can see the problem since we can’t see the glass) :sweat::

Used to other sowftwares like Max in which there is an option regarding the alpha in the reflections and refractions to add it or not (you can choose to affect colour or colour + alpha), we wondered if there would be a similar option in UE5 so that the alpha of the glass is not ignored.

If this is not possible, any advice on how to achieve the desired result?

And, beforehand thank you very much for any possible help you can give us. :smiley:

(As you can see in the image below, the alpha of the glass is totally ignored (white))
