@DrKewp @tnculp @nimlot26 You can be both right? Available doesn't mean DLSS5 uses them? Nvidia confirmed it's using 2D output and motion vectors for temporal stabilization, but it's effectively an AI slop renderer 2D -> 2D.

@tnculp @nimlot26 The mistake you are making is right here. The G-buffers are always available in the rendering pipeline. They don't get "destroyed" at any point and can be referenced by later stages of the rendering pipeline. More...

People keep sending me Daniel Owen's video which basically states that DLSS5 is an instagram filter because it uses just one frame and a motion vector. While his questions were valid and he actually got the replies he needed, his lack of basic technical understanding took him to the wrong conclusion. A lot of you have a very hard time understanding the basics of how a frame is rendered in your game and what kind of information is available before postprocessing and straight up went to the idea is that a rendered frame is like the screenshot you saved on your disk. @ado_tan and his friends have some amazing breakdowns about how different games render stuff. I suggest you to dive on his blog and check all of them out. This way maybe you will understand a bit more about how games are rendered. Here you have an article he wrote about how GTA5 renders a frame. I'm sure it will be eye opening for a lot of you. Till you do your research...I'll just go and play Crimson Desert.

@kringobob @veilofashesgame @GhislainGir No you're absolutely right, ACES is still the de-facto standard. There's nothing wrong with ACES or UE5's implementation of it. The only time I would recommend AgX is when you're doing cyberpunk-ish stuff with bright and saturated neon lights.

@veilofashesgame @GhislainGir Interesting I come from VFX and so use ACES all the time. For me its just a color space, not a "look", so I'm curious how or why Unreal is using it in an undesirable way. I suspect something is not implemented properly or requires some additional setup? I might have to look at it

We replaced Unreal's standard ACES tone mapping with AgX and can finally achieve the grim and rainy lighting atmosphere we were aiming for. The constant battle against unnatural colors, washed-out highlights, and crushed blacks, especially in forests, is finally over!

@GorkaGames Bad textures can absolutely ruin a scene though. I've worked on projects where all albedo textures had baked in AO and non-PBR values (mostly too dark) because "it looked better". Ruined the PBR pipeline. No change in lighting could fix it.

If your scene looks “low quality”, it’s usually not the assets. It’s the lighting Good lighting makes average art look AAA Bad lighting makes AAA art look cheap Fix the order: Blockout → composition → lighting → THEN details

I'd wager those squares are all in one single mesh with vertex animation, it's how we did it at Ubisoft. To reproduce this effect in UE5: spawn a flat plane for each light with a Blutility, merge them into one mesh with Modeling tool, add the shader - voilà!

@KenneyNL @andkalysh Oh I thought it was a 3d software, you mentioned box so I assumed it was 3d

@pr4glik @andkalysh Huh? This is painted in an image editor, it's not a 3D model

I just learned something that I want to share; 1. Create an invisible box with an outer shadow 2. Create an invisible box with an inner shadow 3. Place randomly... TA-DA. Free depth in your texture!

@KenneyNL @andkalysh Wait if it's baked, why not extrude inward and outward for the exact same result for a fraction of the time? You could also literally paint that in an image editor...

@andkalysh It's baked in the texture, so it doesn't cost anything

This is quite disingenuous, you can achieve the same result with no extra verts using vertex painting. If your two top verts are black and the lower ones white, it'll create a gradient that, multiplied with noise, looks exactly like that.

Oh thanks, but I think that's pretty much the opposite of what this blender tool does? The effect isn't hand drawn, it's fully procedural and controllable in real time from within the editor

This is insanely cool, anyone knows if that would be possible to achieve in #UnrealEngine ?

UE Advent Calendar 2025 の7日目の記事を公開しました！ ウィジェット周りをよりスマートかつシンプルに実装できる「UMG Viewmodel」についての解説記事です。 かなり丁寧かつ分かりやすくまとめました！ #UE5Study #Qiitaアドカレ tsubasamusu.com/umg-viewmodel

@flassari Really useful talk!! Profiling GPU in UE5 is pretty difficult due to all the async compute spreading work on multiple frames, traditional profiling methods don't help as much as they used to...

I've been waiting on this one! See how to use our new and immensely powerful GPU profiler in Unreal Engine 5.6+, and how it helps you debug GPU crashes! #uetips youtube.com/watch?v=vnbARZ…

@SheriefFYI @valigo That LLMs alone can't do that? Oh yeah for sure. Thing is, depth perception is a solved problem (for a good decade). If you really want to involve an LLM, the best way to go at it is using LLMs as an interface to pilot pure logic executions under the hood. Don't generate images.

@pr4glik @valigo would you bet money on this?

what the fuck

@valigo @SheriefFYI Not really, it can't get better at this, it's not mathematically accurate and won't ever work in 3D. For it to work it should follow a world model and build upon an internal logic. That's the one thing LLMs can't do.

@SheriefFYI A lot of people are saying that it's not quite correct in these transformations. They are right, but also - this is as bad as it ever gets. And it will only get better...

@RedLadyJJ Yes. Someone struggling to maintain the game at 60fps will experience 57fps in this exact scenario. It doesn't "halve the frame rate", it increases render time from 1ms to 2ms.

I think it’s interesting people are kinda missing the point here. He’s playing on a pretty crazy setup, so if it’s causing frame drops for him, no matter how negligible visually, do you think someone who’s running the game at a much lower framerate is gonna be havin better?

@TipTopToad @DaluzLuciano That's not what they're asking, you're talking about details but they want to know if the normal map values are correct (normal directions). Can you apply it to a cube/plane/cylinder and rotate a light around it?

Good catch, I'll be fair with you. That normal map is does not have enough detail in it if you look at the stone cracks and some of the leaf crumbles but when you use a displacement, you can't tell the normal maps just adds extra hints of detail that react a little bit differently in real time gaming engines. However it's not broken, but you could say it's "insufficient" And in fact, you can just ask nano banana a handful of more times to specifically generate that normal map and not miss those details and it will do it right, like all the AI tools you gotta roll multiple times and deal with trash outputs

Nano Banana has ended 3D texturing. For best results, generate your albedo map first and then individually generate each map you need after that. It will generate any style you ask for, painterly, photorealistic, cartoon, anime.

@AcharaStudios @WillFaucherVFX Is full rough the cheapest option to plug on a depth fade or is there a simplified reflection path?

@WillFaucherVFX Oh no, what I mean is - the more reflective pixels you have on screen, the higher the Lumen Reflections gpu cost. So you can depth fade roughness by distance so that distant surfaces revert to full rough / simplified reflections (there is a separate threshold for detail refls)

A feature I notice many EasyRain users missing is the puddle material function that can be used on static meshes *and* landscapes (Example below is a landscape mesh) You can set the water depth, color, ripples, splashes, all controlled through the EasyRain blueprint. #UnrealEngine

@SebAaltonen The contrast between how large voxels look at your feet compared to far distance is so uncanny, I don't think I've seen this before! It would almost be worth tessellating those near voxels to keep detail consistency 😅

Just added shadows. Now it looks like this:

Didn't you always wish Minecraft looked like this :D

AAA need to stop optimizing for high end. Mass-audience gamers need 60fps stable at 1080p on a 3060. However, the 1080TI is nearly 9 years old and doesn't even support DirectX12... Does it really fit on the right of this graph?!
