as someone who has spent about 2,000 hours on gm_construct 13 i can safely say that the flat window textures in source 1 also use concrete for it's texturing, so at least valve is consistent.

[@hxgonic]

This effect was also used in some source 1 games too! Take the light strips in portal 2 for example, they are simply a flat image but they have this same effect applied to them to give them depth

[@LEDs]

Interesting... I've never used portal 2's version of the source engine, so I didn't know

[@elliejohnson2786]

Skyrim is well known for having many graphical limitations, but it also actually uses parallax on ice! Even in 2011, this technique has been used in games that released quite dated, so it's quite an old and still very effective technique by today's standards.

[@GraveUypo]

if i'm not mistaken, it's even in oblivion. i recall seeing this there.

[@rKaype.]

Certain the Concreate Texture has an Alpha mask baked in and used for the scuffs and scratches on the windows. The Curtain texture in which you were seeing a frame and trees are just artifacts from that part not being textured because they're using a mask to mask that artifacting out (The mask right below it). Would've possibly been cheaper and easier to have baked that mask into the Alpha channel of the Curtain Texture which is something I'm interested into why they didn't do that since POM is already pretty expensive to render.

[@Povilaz]

Very interesting!

[@RT-.]

Is that your cat?

[@StaleCroissant_]

Hey, VFX Artist (student) here! The way parallaxing works is by offsetting the UV's based on the angle on the camera in comparison to the vertex normal of the mesh. A parallax generally used "steps". For each steps of the parallax a certain area of the material gets masked out. It's kind if like how those paper calanders work, but with greyscale images. Ussually parallaxing is pretty expensive since the ammount of layers you need to get a detailed effect can get pretty high. That's why more games are leaning towards depth refection (at least for this type of effect), rather than parallaxing.

[@LEDs]

This video here is a fantastic resource for understand parallax mapping: kzbin.info/www/bejne/mX6ag517qb96ftksi=JEC2PipBAI1vF7lr

[@gamejoker977]

I think the same or similar windows were used in Half-Life Alyx in a few instances. This has given me some inspiration to create some possible trippy textures with some cool depth in vr, wish me luck on my experiments!

[@craftablescience]

weird that no one's mentioned it yet, but Source 1 has a material editor too! it looks like the source 2 version of the tool is based on it you have to launch in tools mode to open it, its called "Material Editor" just like source 2 and is in the same place the particle editor, commentary editor and ActBusy tools are located

[@LEDs]

Interesting

[@leaf_up]

Wow, this is my favourite part of texturing! Ok you've convinced me, I gotta make a CS2 map! Never played the game though

[@stevethepocket]

You might try hunting down places where map makers hang out online and ask around if anyone needs texture work done. I have no idea how map makers and asset makers find each other in this age of impersonal social media, but clearly they do because you never see maps get adopted that are all just stock assets that shipped with the game anymore.

[@Galko655e]

The reason concrete texture for glass is to imitate the dirty window. It's easy to setup from concrete to glass: set color to alpha & select primary color of concrete.

[@Wilzzub0b]

This is the first video I've seen from you and the quality and attention to detail is impressive. I checked your other CS2 videos and they were just as good. Great content man, hope you keep exploring CS2 more!

[@minerkey682]

its a good use of the effect, rather than simply adding parallax-occlusion mapping to everything and having to use like 20 steps to get it looking good. Some GPUs don't tend to handle shaders like this very well, so it makes more sense to use it sparingly

[@666nevermore]

Parallax is everywhere. Sometimes displacement isn’t affordable. It’s a famous technique used to do building windows, it’s not a valve technique at all. It’s actually quite simple, the UV of the texture is deformed based on the camera tangent space. It is honestly used for a lot of things other than faking depth on windows, it’s a little bit expensive to iterate in a loop in the graphics card, so it’s not used lightly

[@LEDs]

It's not simple at all. You just happen to (supposedly) understand it. There are different types of parallax mapping, each with its pros and cons. The version in CS2 only uses three steps, so it's not expensive, but true parallax occlusion mapping is.

[@666nevermore]

@@LEDs in computer graphics or graphics programming this is the standard since many years. The very basic concept of parallax was even present in old 2d games, websites etc. Then there are more aggressive algorithms (should be linear: the higher the steps the more expensive, I think it is O(n) linear in general but I could be wrong). Anyway I have nothing against you or whatever I didn’t want to pass this vibe sorry, just that in my opinion it sounded like you were complimenting valve for a very standard practice while they actually do some incredible stuff that only valve does

[@JarvisDezvoltator]

Your videos are so relaxing and interesting at the same time I really love it thank you

[@LEDs]

[@ferenccseh4037]

Knowing I made a shader that does this and also fills the space in between in godot makes me feel pretty intelligent

[@chyza2012]

Parallax mapping isn't actually that fast on modern gpus, they're great at rendering tons of geometry but comparatively slow at accessing memory quickly, and parallax shading requires multiple dependent texture reads (meaning a texture access depends on a previous result so has to wait for it and can't be done in parallel). Depending on a bunch of factors tesselation (aka displacement mapping) can actually be faster. I'm pretty sure the effect used on the windows is different than regular parallax mapping though, it being distinct layers rather than a single texture controlling the displacement makes it much faster, and that's why valve used it instead of extra geometry.

[@HenrichAchberger]

for brick textures you only need one layer, but uv offset amount is driven by height texture, that creates continuous surface. however if tat is not enough and creates artifacts you need to use parallax occlusion mapping which is more fancy -layered version of same effect I didnt spend 2000 in csgo but I spent 12000 hours as tech artsit

[@LEDs]

There is no parallax occlusion shader in CS2. This three layer parallax shader looks to be steep parallax mapping limited to three steps.

[@perify_]

In Half-Life Alyx, there is a particular brick texture that uses the parallax effect. I can't refer you to the name of said texture but you can definitely make convincing parallax non-transparent materials in source 2. (I'll have a look for it and if I come across it I'll leave it here) Edit: I managed to find the texture. It is "brick_2a_parallax". If I'm wrong about my suggestion please be free to correct me.

[@bengregg2632]

YESSS, I was gonna comment about the same thing. The odd thing about that brick texture is that I don't recall it ever being used anywhere within HL:A... makes me wonder if it was just made to test the shader and the devs decided "nah, let's not use this shader for [insert development/performance reason here]"

[@LEDs]

Is it a 3-layer parallax shader or full-on parallax occlusion mapping?

[@bengregg2632]

@@LEDs I THINK it's a proper parallax occlusion shader, but the way it renders is VERY similar to the 3-layer parallax shader (just a series of layers, except with a near-infinite number of layers and each layer is dictated by a depth map). idk if that's how parallax occlusion shaders work in other game engines

[@bengregg2632]

@LEDs the parallax shader (in HL:A) is called "Vr Parallax Occlusion", if you want to toy around with it

[@Mici1]

"This is LED switching off" wait that outro kinda goes hard

[@PumpkinHook]

At 3:05, you talk about how the material uses a Normal Map with seemingly no detail Looking at the texture in the file explorer we can see it has an Alpha Channel, meaning there is likely more information stored through just the alpha, although I cannot say what information as I havent explored the CS2 materials myself personally. Edit: Thinking on it and seeing how replacing the normal map with a blank one changes the effect; it is possible the alpha texture is some form of bump map texture? Although that is an assumption built from the lack of information seen.

[@LEDs]

That could be true
