This BSDF is so simple but utterly insane. I don't think the guy who casually dropped that into the code out of nowhere was quite aware of how much this allows us to do.

This is so so so useful: - This could be used for NPR lighting, portal from the complex geometry to a simpler mesh lit by it's own lights elsewhere in the scene out of view - TV screens without the need for packing video frames into a texture or post-render compositing - Fake deformation like the sphere in the video could be used to do that Inception effect of the city bending on itself without actually deforming tons of geometry for real - Cheaper character rig deformation by having low poly rigged geometry portal to a static high poly character

This looks like one of those things thats a game changer but I’m too dumb to know why.

wait a minute. you could literally plug in a height map into the vector math node you use to define the perspective. if you invert it, it will act as if the camera is looking "down" a different heights based on the displacement/height map.

9:48 To save everyone from the whole having-to-use-drivers-to-undo-object-rotations-business, you can just use Texture's Coordinate's Normal output instead of Geometry's.

Portals in Bkender is something I've wanted FOREVER, to get a similar effect like the portal games

I cannot wait to use this for building windows holy shit

finally it's possible to render a novel vantage point in the scene to a plane! You can make CCTV survelliance, portals and non-euclidian space illusions in a single render!

Now you're thinking with portals!

Losing my mind over this. Nodevember is gonna be a lot of fun

I was waiting for node like "image from camera", but this is so much better

honestly super exciting, not everyday that we are given such fundamentally mind-boggling different toy to play with

This would make it easier to animate 3D televisions without having to do separate rendering, saving hours... days... potentially weeks of rendering and post processing!

You are a freaking genius, thanks for being so curious about things and thanks for sharing your discoveries with us :)

I've been waiting for something like this for so long, genuinely awesome- Especially since it'll allow for SUPER realistic black hole visualizations (stacked planes w/ some """velocity""" data baked into the texture itself)

HOLY HELL, I almost jumped up when I saw the moving preview of this video. I was like "I NEED THIS" Edit: I have so much ideas, this unlocked so much things for my adhd brain

This is great for so many things. The first thing I thought of was I wonder how this compares to the parallax method (like what you were building) for things like faux 3D rooms in windows, like you see in video games and stuff. With this version, you could create 5 or so rooms that you keep somewhere out of view, and make copies of this node tree that's mapped to look into each room, and put those texture on the windows. You might also want to make copies for each direction the windows face, because then it'll capture the sun lamp coming through the windows as well. This way you'd get nice, accurate lighting and real depth in the rooms, but it's essentially instancing and only calculating the lighting once and multiplying that for each window. Would be interesting to see the difference in quality vs performance. Also, being able to have actual portal and stuff is fantastic.

Neat! Maybe this could be used to make lenses?

I can't even fathom the possibilities, this is insane

Alright, gonna have to watch this atleast 3 times

This is HUGE. Thanks a lot for the video. I've wanted to use this for so long but I didn't want to buy some add-on or get a PhD in Blender Nodes to get this effect.

I have been asking for exactly this for years. This is great.

Thanks Mr default, this is insanely cool

this is really cool im so glad i took the time to watch this

Great vid i actually understood what was being said most of the time keep up the good work👍👍

Mind blowing. Brilliant!

This is amazing. My question is how much does it help performance? Say I use it ith a building to replicate a 3d office on every single window of the building. Would it just process the one office and all the window polygons or would it also process the "new" offices that you can see with this node?

OMG this is stupid awesome! Thank you for sharing, I have so many ideas.

This would be great for CCTVs.

LETS GOOOOO

This allows for crazy fast sprite generation, if you consider the cube+negative normal example. If that cube then was unwrapped to look like a sprite sheet, you could render all angles of a given srpite, at once. And if you used something like a n-sided cylinder, you end up with even more angles, at once. Kinda wild

This is awesome!

I spent hours trying to fake this effect with the sky/environmental shaders. Since the old portal method with layers and composite tricks was lacking. But this is exactly what i needed.

1:13 I hope Eevee next could render this types of node

Woaw !!! Thx for this video !!!

Awesome, so brilliant

That's AWESOME!

Damn that's super cool!

I actually made an addon for architecture that depends on classic parallax techniques with some spice , this trick will be insane if you can hide viewlayers for example and drive the rooms with geonode and create fake interiors but in realistic lighting all across the town for example !!! , holy spagetti it will be insane 😀

the tensors are evolving!

Holy shit, this got so much potential!

insane.... thank you!

This also useful for create Forced Perspective 3D Billboards video content.

Cubemaps in blender, neat.

I would love to make a magnifying glass with this

In so early it's only available in 360p. :-) Great exploration of the new node!

It’s tardis time guys

Wait no fucking way this is amazing. I can do some INSANE stuff with this

Oh my god! I can finally do 5d space in blender. Yay!

this is HUGE for vfx.

OHHHH I'VE GOT IDEAS... 4:17 this just made me think not only could this be good for mapping images, windows or portals. it can also be a good way to create a TV effect where you have a monitor and have it display another part of the scene basically doing 2 things at once. (I don't believe in current versions for this to be possible however this Ray portal node will change SOOOO much)

you could plug a height map into the vertical offset instead of using a single value for some interesting results

BRO ive been wanting this for fucking forever!!

In LightWave you can use a sphere (or any geometry witha UV map) and project outwards to make an HDR map, can you use this for that? It was a very useful feature

Could you use an empty to control where this portal is viewing? Figure it'd make it very useful for animation this effect!

FUUUUUUUUUUUU!!!! thats a amazing!

Welp! Here come liminal spaces and holographic interfaces :D

You are the best

What a coincidence... I'm currently enjoying and at the same time finding it confusing to play with the parallax effect in Blender, and then this video came out.

OH MY GOD THIS IS AMAZING this will make my projects 1000x easier

I've been making pokemon cards with a 3D effect and it's been a nightmare and with this it's going to be a godsend

now we just need to wait for someone to make a tardis model with this node.

Thats's freakn great! I wonder if this works with blenders scenes? PooOOOOOOooower! 2nd demoooOOOOooo? 👌👌👌

I imagine this would make possible virtual cameras like we have in raster engines, where you can place a camera anyewhere in the scene and display what that camera sees on a surface, say a TV screen?

yay mirrors

Will be able to fill out skyscraper windows in no time now.

you could use this shader to create some really cool infinitely recursive things and i am SO hyped

just in time ☕

Now we're thinking with portals

Now we can make tv screen with broadcast😊😊😊

game changer

I'm just getting into Blender (literally just made my first donut the other day), but this seems like it'd be a really simple (cheap) way to do a fake water simulation, yeah? Something like applying an animated wave distortion to the Ray Portal BSDF (or the plane's geometry) and caustics to the original geometry? It'd probably never offer the same realism as an actual water sim, but it seems like it'd do well for smaller, calmer bodies of water viewed from limited directions

Can't we use this to make some sort of simulated camera inside blender? Then maybe use it to broadcast something else on a tv? better yet save said camera to use for all kinds of portal things? an empty as the center point, a plane as the end of the camera, and moving the plane would change the POV? Maybe probably?

Imagine if we can render lots of assets in a huge scene this way, hope it improves render times.

nah thats crazy bro

That Incoming to Tangent space converter is quite nice and exactly what I was looking for. So I got a plane which is basically always looking down no matter how I move and rotate it. I just cannot figure out for the life of me how to rotate this view so that the plane is always looking to the left or always looking to the right, no matter how I move and rotate it. I tried it with Vector Rotate etc. but it mostly gives only distorted results.

Bruh, I've got to make a snow globe now....

"Damn I wonder if it's going to be a portal"

I'm a developer, and I'm astonished by your skills in math (for an artist LOL)

genius

this is the most mathematical blender tutorial I have ever seen

It is really differend from parallax mapping anyway. You can't use this portal nodes for materials because image in the portal isnot affected by lights around the portal

maybe we can use it to make bootleg render-to-texture stuff for security cameras and the like

Oh boi the quick&easy pipe for making psychodelic/surrealistic mindfucking stuff just droped xd

Wow, it looks like those old-school “holograms”

I was literally wondering whether this kind of thing could be done in blender mere HOURS before you dropped this video wtf

So this is going to be a bit above the pay grade.. ❤

4:13 Getting some serious stalker vibes

This is sick. My brain can not process.

Could you theoretically create building windows with this, perhaps linking to a geonode based interior off to the side? I wonder how the performance would do rendering that many instances.

You don't need to use vector rotate + drivers, instead use the vector transform node, to transform from world space to object space. Edit: Or as another comment said, use the normal from texture coordinates instead of geometry, which is in local space.

6:28 What did you just call us?

Please make a use case video for this node, i don't understand what people are soo happy about in the comments.

wait... Did blender just achieved nDisplays from Unreal, but in Blender? This has a HUGE meaning for projection mapping and mapping shows if that s the case!

A GDC presentation on Quaternions dropped this week which helped me get an understanding of what/how/why they are useful. As you created your tangent space equation my brain woke up when you used the dot produce of each… I wanted to ask is the dot product -1 to 1 serving as your “weight” here?

When is that getting released in the main version?

Does this simplify the looking glass hologram type rendering at all?

headache button (also i love his content) >>>>

A lot of pain could be solved if they had an absolute/relative toggle.

You could just spawn a camera and use that camera as the object's camera
