For example: I need to make a horizontal portal that teleport you to a vertical surface. (like at the first pic)

But I built my house (or something else) contrariwise and I need to see the view from first pic from the other side

contrariwise

LOL

I think any rotation is possible with set_portal_rotation. Just try stuff until you get what you want? might need to type some square roots and things into google

If the reverse portal is generated by complete_bi_way_portal, it will use the inverse rotation to make space "connect". If not the teleportation will not be seamless

have you tried actually rotating the portal body around the Y axis? As in, rotate portal body, not set rotation

have you tried actually rotating the portal body around the Y axis? As in, rotate portal body, not set rotation

It do nothing

whoops, forgot rotating the portal body doesn't actually rotate anything else xD
uhh... maybe I could add a new command add_portal_rotation

Okay, I'll wait

Oh, okay

this is a valid issue

So, I think rotate_portal_rotation can help me now
