Hello there! I would like to add a detail to manage expectations regarding Enscape's displacement mapping.
Our technique operates at screen space and doesn't alter the geometry. This means that we employ some tricks so that the surfaces of the displaced materials appear to have some depth but the geometry stays exactly the same. Even if you find a seamless texture with displacement, you will still have straight edges for the walls at their boundaries.
A seamless texture will help hide this when two surfaces with the same material are connected but it won't help when two surfaces with different materials are next to each other. In the image below I have emphasized the edges that stay straight with displacement maps.
Hope that helps!
