"In portal maps, you can create portals on walls. Such portals can be entered to end up in another world. "
"The portals are 'immersive', that is, you can see through the portals. In the current implementation, "
"the immersive view works only in the raycasting mode, for rendering walls -- so any other objects will not "
"be rendered. (You can turn raycasting off to see the world without any portals.) As a consequence, "
"there is no HyperRogue game in a portal map -- you can only move the camera around the scene. Pick "
"'set recommended settings' in the manage portals menu to optimize settings for this.\n\n"
"To create portals between different geometries, you need to create a map in the other geometry and save it "
"(using the map editor), then in your portal map such a world can be loaded to be added to the scene "
"(in the manage portals menu). Such portals work correctly when their intrinsic shapes are equal (including the "
"curvature), their extrinsic curvatures match, and are actually implemented; see the video 'Portals to "
"Non-Euclidean Geometries' for some portals that work.\n\n"
