Seamless Portals - An easy to use asset for creating seamless portals in your game

Community Showcases
1

This script allows you to easily create seamless portals in your games.
This is great for creating more fluid gameplay as well as making your game look cool.

There is minimal setup required to get the portals working but there are configurable settings for a more versatile system.

You can apply a mask and background texture to your portals if you would like to overlay an effect, such as a border or window panel effect
On top of this you can disable teleporting for the portals so that they are just ‘windows’ into the other world that cannot be walked through.
The portals can be configured to teleport:
-The player camera
-The player camera’s parent
-An arbitrary GameObject which can be used as reference for more complex player controllers
for more info on this, check the documentation

As well as the documentation, you can hover over any of the settings in the configuration panel and a tooltip will give you short description of what that setting is for.

For examples of how this tool can be used, check out the included screenshots and video.

And here is a little video to show the sort of things that can be done

Is this possible in Unity ?

Looks good!
Can this asset be used in an AR setup?

By AR I assume you’re talking about the issue of having two cameras.
If that’s the case then yes it is possible but you will need to have two sets of portals - exact duplicates but with each set configured and visible to only one camera/eye.
Hope that makes sense, if not I can help more

No, not VR - Augmented Reality.
The camera renders the phone camera view and then the meshes.

That would work?

So you would want a portal to render in the camera view as though it would be there in real life, but what would you want to render inside the portal?

The portal is just a cube/plane with a fancy texture so if you want a portal to gameworld that renders as though it was in the realworld (via a camera) then yes that should be possible

Cool! A portal in the real word, entering a pure 3d world would be it!

Thanks!

Yeah I would say that is definitely possible, if you have a simple AR demo setup you could send me I could add in the portal to test and show you first, or alternatively I would be happy to refund you if you bought it but couldn’t get it to work for your purpose

Just assembling potential ideas to come to life, nothing ready yet. Tba

Alright no problem, let me know if you have any other questions :slight_smile:

Do you know if this would work for PSVR?

Hi - great asset.

Can the portals be created on the fly?
And can the portals be moved after created?

12

Hi sorry for the late reply, The portals could potentially be created and removed with a script.
Thinking about how they’re setup, you may have an issue if you have more than one pair of portals (but only if they can ‘see’ each other, otherwise should be fine)

The portals can be moved and they will continue to work :slight_smile:

Can you add support for VR?

14

I strongly second this. Every project I find with seamless portals (that still works) doesn’t support VR, and contains descriptions on how to modify the existing setup to achieve it, which they say is “easy.”

I’m not a new dev, but I’m fairly new to VR. Multiple cameras, frustrums and rendering to single “eyes” never seem to work correctly when I try to set them up for my Vive.

Another thread just brought up the idea of non-Euclidean levels. Could you do that sort of thing with this asset? I assume the 3-rooms-connected-as-if-they-were-4 trick is pretty easy, but what about things like scale transformations?

16

Just bought this asset. Pretty happy with it so far, except for one thing: I didn’t realize it only supported one pair of portals.

I can design my layout so that you can’t see one portal from another, but I still need a total of four pairs… how would I set this up?

17

Also… a lesser issue, but: this portal is double-sided. All my portal needs are single-sided. That is, I should see and be able to use the portal when I approach from (say) the south, but if I approach it from the north, I don’t see it and it shouldn’t bother with its offscreen rendering.

Any idea how I could go about making these one-sided?

Hi

First up, just to let you know that the best way to contact me is by emailing me at josephpatrick2013@hotmail.com as I don’t always check the forums too often :smile:

So thanks for buying the asset, while you currently cannot link more than two portals together, you should be able to have multiple pairs of portals, you will just need one PortalConfig script for each pair - though you may find each pair needs it’s own material.

The portals are double sided by choice by using flat cubes, if you would like single sided then just use planes instead.

Hope that helps

Really like this asset and have been able to easily set up multiple portals to move around the world. I have been trying to use this asset for a VR game but there are some issues with the camera. It is related to the question about VR/AR above and the configuration with duplicate portals.
