As you can see in the image, I have a wall, and the opening on that wall is covered with another wall, kind of like a hidden passage. When the user gets close to that “opening” the small wall disappears and opening appears. Before the user gets into the proximity of the “hidden wall”, I would like to see no difference between the two walls, it should look like one. Even though I’ve adjusted the the texture size, and the brightness of the material, you can still tell there is something there.
What am I doing wrong? Or any suggestions?
