A method includes: triggering rendering of an augmented reality (AR) environment having a viewer configured for generating views of the AR environment; triggering rendering, in the AR environment, of an object with an outside surface visualized using a mesh having a direction oriented away from the object; performing a first determination that the viewer is inside the object as a result of relative movement between the viewer and the object; and in response to the first determination, increasing a transparency of the outside surface, reversing the direction of at least part of the mesh, and triggering rendering of an inside surface of the object using the part of the mesh having the reversed direction, wherein the inside surface is illuminated by light from outside the object due to the increased transparency.
