how did you do this

i can tell its viewports on surface guis

because of the shadows

but what data are you sending

is it as simple as giving it the entire world?

[deep osprey]

or only give it the current stage or something if your making a game out of this

[next vine]

yeah it’s only the current level in the viewport

Woah how tf ??

U can put live holes in walls?

i mean you can using csg, but this isnt using that.

the level isnt being modified at all, the portal surface is a Part with a SurfaceGui with a few tricks!

[next vine]

theres 3 main parts to what is seen here;

• portal renderer
  -- the level 'inside' of the portals that get updated
• placement algorithm
  -- shooting the portals at a surface and finding a valid position for it
• portal physics
  -- disabling the collision of the world for the player while inside a portal and teleporting the player at the right time

separately these 3 are pretty simple, its just a matter of syncing them all up to give a convincing result

[lyric nacelle]

its super cool

neveer seen it before

good job

[vernal birch]

simple when u think about it though

plop the entire world into a viewport frame

align it with the lookvector of the part it was projected onto

Done

[next vine]

actually no

that would leave you with a flat, image of the world
