I don’t know if I will be clear but what I’m trying to do is first:
Having a skybox and in the middle of the scene a cube. your camera is in front of the cube, so the front mesh of the cube will take what you see behind the cube, so the part of the skybox.
Then what I want is to keep this texture (as a screenshot) into the face of the cube and when you rotate around the cube the texture on the face is what we saw at the beginning.
Technically I want a little bit like this PG: https://www.babylonjs-playground.com/#UU7RQ#3
But I want to see what is behind the cube and keep it on the face I don’t want to see what it’s reflecting.
