Is it possible to create a Loop map?
and if yes: HOW??? 
Whats a loop map? Define it.
for example you are in a little room with a door on the right and a door on the left…and if you walk through the door on the right you’ll come out of the door on the left (i know that my explanations are not that good^^)
another example: a dessert…if you’d mapp it its only a small map…but you can walk and walk and walk…and you’ll never reach the end of it
Sure, you could make a square or rectangle of seamless 3d model with seamless textures (so if you tile it, there’d be no seams! ) and then if you have pro, set up walls on all four sides, and four cameras on each wall facing inward (perpendicular from the walls) with a renderToTexture to set the texture of the other opposite wall. then set the walls’ colliders to isTrigger… and have it so that when a player gets close enough to a side, transform.position = new Vector3(); where that new Vector3 is on the opposite side of the map where he might be if you tiled the map.
I would make a prefab out of your tile, and create a pool of them which could be activated/deactivated at the locations around your current tile, as you walk towards them.
Or you could use the Prey Portals scripts that someone posted, which would make you essentially be teleported back to the other side of the room.
mhh ok thx guys
i’ll try it^^
