[@dawdledev]

Awesome tutorial! I really appreciate that you both explain the shader and include a full view of the shader graph so it can easily be recreated! The struggle to recreate a shader using nothing but gifs of the finished product and maybe some code that doesn't work anymore is the worst part of game dev.

[@markscott6927]

Back in the day when I worked for a larger game publisher, central tech did a presentation on several shader options for the XBox and PS3. What they called a ' depth shader' is what we have here. This was ~2004. After playing with all our nice new shaders we were immediately informed that they were too expensive to use. And such is the life of a game artist

Things like that are what makes game developing so much interesting and fun to mess with these innovations are so interesting to come up with even in smaller scales. it does make it more difficult than challenging to accomplish but it adds more magic to it and makes everything so interesting.

i made a new playlist just because of this video called "stuff i should put in a game" Just seeing a practicle demonstration of this helps understand ideas that are within ones grasp. Thank you for reminding me of that.

I was today years old when I realised Spiderman didn't have rooms rendered behind those windows. This is an amazing technique, and one which I would love to make use of in future projects!

It took me a year to find a time and watch this video saved in my downloads. I do not regret that since I am learning shaders in details and I can better understand how powerful this trick is. Thank you for another great video!

[@avatar098]

I'm a software developer by trade, but video game developers have always inspired me. Y'all are literally the intersection between art, story telling, and computer science. So I've been dabbling a bit in video game development, and man, what you guys do is NOT easy. Much respect for content creators like yourself!

[@alexpaww]

Sadly, professional video game developers are chronically underpaid and overworked. Not a great industry to work in.

[@KentHambrock]

There's free drop in resources on the Unity Asset Store for this, but I love that you built it from scratch and showed the process for those of us who want total control over the process.

[@coderious4568]

That is true dedication, great job!

[@timothysnave]

That's really cool. Just a note - the pacing in these sandbox videos is, IMO, way better than your other videos (from what I've seen so far). Sometimes I can't keep up visually in your other videos. This weird concept exploration format is gold, though.

[@connoraustin22]

Great tutorial as always, you have some of the highest quality game dev content on youtube. Another suggestion that I would think would be helpful, and go along with your strategy/city builder game theme that comes up in some of your videos, would be a tutorial on how to create a 3D based grid map system, Where buildings/units/roads are snapped to a grid when placed. This would be a great niche to hit, as the current tutorials for this on youtube are either poorly made or use an inefficient method to create this. Cheers

[@RoseIllo]

Fun fact! One of the examples you gave for blackout windows, Cities Skylines, does actually use a technique similar to this, with the exception that it only shows the floor inside the window, that fades into the distance. So you have interiors, but the interiors are all empty wooden floors and nothing else.

[@AaditDoshi]

Great video! I appreciate your efforts! I just wish you went into a little bit more detail about why something went wrong, and how changing it fixed it, an example is around the 4:15 mark

[@tajaloe]

My brain: render out a room in one image with a depth map. Use those textures on a model and use inverse camera mapping to displace using a parallax node. idk if that works lmao I haven't tried it, but someone should. Probably not as performance Friendly though, but hey, you get per object depth information at the sub pixel level, so that's cool I guess

[@KusalGunasekera]

That's exactly what I was thinking, we could improve the illusion of depth specially for the things that stick out. But then again, if you're using it for something that will whizz by at 250kmph then there's no point XD. Maybe for something like spider man, they can replace the faked room with a full 3d room once he gets close enough to the window

[@stan_p]

you can get a real struggle doing this, cauz you adding things you shouldn't. Depth map cant be baked on the UV of cubemap, so this is first problem to solve if you about to mix those pipelines.

[@lukabrasi001]

@@KusalGunasekera honestly, in Forza Horizon 5, the normal cubemap approach works really well, things look 3D enough with a little trickery

Really cool stuff. It would be cool to do some kind of comparison test with this way and the more traditional method. I'm curious to see the performance of this technique vs the simpler one.

I would LOVE to see a video on projection decal shaders. I know that HDRP has these built in, but I would love to have it decomposed in shader graph so I could do some more custom processing on the texture that gets projected.

[@damiangonzalez_esp]

Excelent video! Thank you for sharing this knowledge

[@javimania111]

In 2005 this technique was used in a game called Trackmania Sunrise, in buildings in the bay enviroment. The effect didn't look as good as in current games, but it's still quite surprising considering the time.

[@YognaughtAce]

wow, that is incredible

[@juanquireyes6703]

must be nice to be a genius like you

[@Bobby_Go]

Do you still need to flatten the objects along the walls after you negated the tiling values at 6:56? Wouldn't that also fix the skewing of any objects in the room, like at 6:08? Or will that always be the nature of this type of projection?

[@Jewalify]

This is so cool. It only works in 2D. In VR this wouldn't work, you would be able to tell that it's a flat surface but it would still kind of look like it had depth

[@freeju2001]

Fantastic video, thanks so much!

[@mohammadsadeghlavaie5560]

[@MarcelGrolms]

Amazing! Would also be interessted in how the script works to get the cubemaps for the rooms. I already learned so much from your videos, thank you!

[@GameDevGuide]

It's literally the editor script shown in the video. That's all there is to it. It uses the default Camera.RenderCubemap feature as I mentioned.

[@AlexTuduran]

Nicely done.

[@julienheijmans]

Really nice video ! I was thinking that something that could be cool and give it a sense of increased fidelity would be to display some curtains that are displayed with a smaller parralaxe offset in front, on the sides of the windows. That would give the illusion that the player can see what is behind the curtains. (Said curtains should then be in a different texture, not integrated in the cubemap, of course)

[@swagguy47]

The Crew 2 does this effect really nicely.

[@SirFency]

Well done sir.

[@senaesul3128]

Because light from the sun is much brighter than any light coming from the rooms, it would be cool to see the textures darken in certain conditions that involve competing light sources. Side note: I really feel like total reflection on windows (when viewed from a steep angle) is super unused. There were many cases in the video where I thought, "In real life, that would probably be impossible to see into because of the reflection".

[@AL2009man]

Geez, imagine a combo of procedure generated rooms and this shader. It would be amazing!

[@piromansadran]

bruh thats amazing

[@adamking816]

nice work !

[@njebs.]

Really cool video! As a followup, could you potentially create a system that automatically randomises each room for every iteration of the cubemap, just to add that extra bit of variation?

[@GameDevGuide]

Yeah, there's a lot more you could do with it. In theory, you could expose the Cubemap properties in the Shader and set them on an instanced material using a script for something like that.

[@Bolt6265]

You could also use a texture array for the cubemaps and sample from it using some simple rng to make it less tiled. Idk, food for thought.

[@jakeecake]

This is really cool, was wondering if you could plug in an animated image and have a person in some of the rooms? maybe someone on their computer making minute movements so they don't break that depth illusion

[@chuukoart3869]

I'm pretty sure you can just use a reflection probe to bake a cubemap from a scene as long as the objects are static. That's what I did for a game I worked on and it saves as exr which I could just open up in ptohoshop and edit

[@Doomness2k]

Wouldn't using a orthographic camera instead of a perspective camera to capture the cubemaps work better and fix the whole "having to squish things down"?

[@DARK_AMBIGUOUS]

1:29 how did the room change???

[@Daedalus29]

Gotta try this with spaceship windows, I hope it will bring a better sense of scale compared to the drawed windows on huge ships

[@sanderoneil6998]

this tripped me out bro

[@lukezhou6349]

I guess how the interior mapping shader works is by intersecting camera rays with imaginary cubes behind the plane. Moreover, I think that by pulling the camera out of the window and un-squishing all the geometry may produce better results (which means that you can't simply use a cubemap anymore).

[@zig8925]

Hi Matt! This video is just awesome, the only thing I can't seem to understand how it works is the cube you made in blender with the rearranged UVs. How did you do it? Thank you so much for all the work you do!

[@YVZSTUDIOS]

That looks awesome! Do you perhaps have any tips on how to do the opposite? An interior scene with windows as walls that have nice reflections? I've tried out reflections probes with cube projections, but the illusion breaks if I'm change my position. They look like flat textures instead of real relfections.. I'm literally at the edge of just copying my geometry (like how they used to fake mirrors in the old days) Any help on theat would be awesome (from anyone actually) 😭🔥
