The disclosed computer-implemented method may include (i) associating a planar element within a virtual environment with an alternate virtual environment and (ii) rendering the virtual environment such that (A) the alternate virtual environment is framed within the planar element, (B) at least one rendered element of the alternate virtual environment renders at a distal depth beyond a proximal depth of the planar element within the virtual environment, and (C) altering a viewpoint within the virtual environment relative to a position of the planar element within the virtual environment produces a parallax effect between the virtual environment and the rendered element of the alternate virtual environment due at least in part to the rendered element of the alternate virtual environment being rendered at the distal depth beyond the proximal depth of the planar element within the virtual environment. Various other methods, systems, and computer-readable media are also disclosed.
