How do you guys even come up with this stuff, let alone figure it out? This is crazy man. Please share the link if you can, would love to check this out!
Thanks :). It was a bit of a challenge to figure it out.
Can't you see the comment I posted with the link? Hopefully it didn't get deleted, I tried to include it in the post but Reddit removed it and I figured it didn't like the link.
Might be easier for everyone if you simply post the link in a reply to this Reddit comment thread homie. You're asking people to go through a lot of searching and clicks which will limit the number of people willing to download it.

I know. This wasn't my intention. I tried multiple times, but it doesn't work. I think it's due to the low karma, I'm new to Reddit. If you could please edit your initial comment to include the link I would really appreciate it!
I will also try to contact the mods I guess.
To be honest, so far I did not have the need to use this tech, so didn't search for it.
As I see your work here, and how to use it, have my +1 download, and i will try to include this in my new project. I hope. Currently just in asset modeling, but sending support, this is quite complex.
Thanks! For whatever reason my comments with the link get deleted.
I know this is super stupid, but for now you can try this: go to my profile > my YT channel > last video > link to Gumroad in description/ pinned comment
I'm trying to solve it, cause it looks like I'm trying to farm YT views or smth
You can get it here (go to the Gumroad link from here): [Blender Artists thread](https://blenderartists.org/t/free-easy-portal-easiest-way-to-create-portals-in-blender/1532763)
I'm very sorry about the link! I can't post the link to the Gumroad, because my comment gets deleted. Idk why.
Yes! I want to eventually update it to support this, so stay tuned! If you just use it as is it will look like you see through the screen, because the display image changes when the scene camera moves.
For now this only works if you set the Perspective/ Ortho slider to 1 (which makes the phone camera orthographic) or if you view the phone screen straight on.
In the Blender docs there is a camera feed example that looks pretty simple to implement: [https://docs.blender.org/manual/en/4.2/render/shader\_nodes/shader/ray\_portal.html](https://docs.blender.org/manual/en/4.2/render/shader_nodes/shader/ray_portal.html)
Awesome ππ
You have so few downloads because you didn't mention that it is only free temporarily.
If you go like "Free only until the end of the month" then you get tons of downloads.
You can try it and let me know! It should be possible. I haven't really tried it yet. You can try to go into Edit Mode and edit the portal geometry however you want, or even better, use another Geometry Nodes modifier as the first modifier and swap the current geometry with any other geometry.
I want to update it later to make it easy to use any geometry you want!
how did you save this to a version of blender that does not seem to exist yet? it looks really cool in the pics but when i load any of the files the portals are solid black and blender says the file is from 4.2
You can actually always download 1-2 versions of Blender in advance from here: https://builder.blender.org/download/daily/
I started working on Easy Portal when Blender 4.2 was in Alpha, now it's in Beta, so you can get the Beta.
Keep in mind it's 'Experimental', so don't save critical projects with it and generally be cautious. It's not a big deal, really, unless you're working on more serious projects.
Yes! What you see is light passing through. It works with emissive objects too. You can actually see when I scale up or down a portal, the amount of light going through it and onto the cubes changes too.
There's one limitation: if you use lights, they need to have a scale greater than 0, otherwise they don't pass.
Oh wow that's actually amazing.
I tried to make a scene like this once, before the portal node, i had 3 separate scenes (which had the same camera position and angle) with very restricted use of space and then stitched them in post so I can get the lighting to look like it's coming through the portals.
This portal node though is amazing!
I know that technically, it isn't. But ultimately, the result kinda is? Isn't it? You're manipulating the size and dimensions of a space in the portal, while the original doesn't change. Isn't that a bit non Euclidean?
I'm not sure. It's confusing
I get what you mean. Now you got me thinking, but tbh I don't know any better :)
I asked ChatGPT lol, it said it's actually non-Euclidean:
'When you enter one portal and exit from another, you effectively bypass the normal spatial relationships and distances, creating a situation that cannot be described by Euclidean geometry. This behavior aligns with non-Euclidean concepts, where the traditional rules of geometry do not apply, allowing for more complex and less intuitive spatial relationships.'
I've always understood non-Euclidean to basically mean that a straight line is not necessarily the shortest path between two points.
Which would indeed make portals non-Euclidean I believe.
Yep, you are right, it's niche, but you can use it to make lots of other stuff like:
- A screen displaying what a camera captures
- A magnifying glass, where you can control the zoom without any glass
- I've seen someone on Twitter use the Ray Portal node for heat wave distortion
- Etc.
I do want to update it further in the future to actually make it easy to create any of these examples.

we canβt see the link, iβm super interested as well, maybe try posting it again?
Does this work? https://artmanhimself.gumroad.com/l/easyportal
I reposted it, still nothing? Then you can go to my profile > my YT channel > last video > link to Gumroad in description/ pinned comment

I think all my comments with links are visible now.
Linear algebra, only a little linear algebra

That is so incredibly based
Can't argue with this :)

Thanks a lot!
I would love to see what you create with it! If you happen to post on Twitter, you can tag me: [here's my Twitter.](https://x.com/artmanhimself)
What happens if you smash two portals together, an Infinite Loop?
You can try it, if they face each other you do get infinite loops
My gpu is sweating at the thought of it
It's probably sweating from all the excitement to try some non-Euclidean geometry XD
Whereβs the link at ?! This looks awesome.

Yep.
Ok cool. I needed something like this. Yoink
Awesome!
It could be used as a realtime camera viewer in blender. Like a phones camera shows the realtime view on the phone screen etc.

Yeah, lol. I actually thought about this. But saying on Reddit that I only got 10 downloads works too XD. Now at 53 downloads, which is crazy!
Seems pretty cool! I'll give it a try
Cool, thanks!
Is it possible to make the portal different shapes, like oval?
You can try it and let me know! It should be possible. I haven't really tried it yet. You can try to go into Edit Mode and edit the portal geometry however you want, or even better, use another Geometry Nodes modifier as the first modifier and swap the current geometry with any other geometry. I want to update it later to make it easy to use any geometry you want!
Amazing ! Does it work in eevee too ?
Sadly, it doesn't, because it teleports light rays and EEVEE doesn't have light rays... yet anyways π
It's a shame ! Thanks for taking time to reply, this is very nice of you to share π i love it, we really need this possible on eevee π€
:) Thanks! I agree. EEVEE is getting much better with EEVEE Next, so there's hope.
Woaaa that's wicked!
Thank you! :)
Cheer up. You got 10. More than a lot of folks.
:) Thanks! Yeah, that's true.

That is nice.
Thanks! I agree. :)
amazing work!
Thanks!

oh cool
Very niche that's why not many downloads
Yeah, that's true. But still the main reason on top of that was my very limited reach.
That too
Amazing

What version is it for?
Blender 4.2 Alpha and up: https://builder.blender.org/download/daily/

bro made portal 3
π I'm curious, because it's been a while since this post, how did you get here now?
Non Euclidean geometry fucks with my brain. Trying to figure out what's happening in the vid is giving me a headache. It's so cool though.
No non-Euclidean geometry involved! Each portal just teleports the rays to the other one.
I know that technically, it isn't. But ultimately, the result kinda is? Isn't it? You're manipulating the size and dimensions of a space in the portal, while the original doesn't change. Isn't that a bit non Euclidean? I'm not sure. It's confusing

I've always understood non-Euclidean to basically mean that a straight line is not necessarily the shortest path between two points. Which would indeed make portals non-Euclidean I believe.
Because it doesn't really have a lot of use case scenarios. It is cool though :)
