This is weird! I have changed the texture of a wall from brick to stucco but the rendered image shows the non-selected brick texture. (It may actually be showing both textures, with the stucco showing through faintly - I can't be sure.) Q1. How can the render show a texture that isn't selected and which doesn't show in display mode? Q2. How can I delete redundant textures from the RenderMaterialsTexture-Map drop-down menu?
