So I’m working on remastering some old models and I want to increase their texture quality. Using photoshop only makes it blurry and it loses detail. My question is, Is there any AI software, or app, that can increase texture quality for free? I know let’s enhance exists, but the 5 pics limit makes it a no-no.
Also, my pc died and I’m stuck with a mac for now. So hopefully it works with a mac, or i can emulate it with one. I’ll go back to windows after that.

but there is no way around creating proper high res textures by hand

So you want to create more information from nothing, while doing nothing, for free.

No you fucking retard, that's not how it works.
If you want more quality you have to put some effort into it.

just use sharpen and contrast. it will looks more modern

Interesting. I wonder if it would give good results for skin textures.
>>
>>656700
It tends to look OK for environment or landscape textures, but it messes with seams on UV mapped textures.

It can also introduce some strange haloing and noise patterns, depending on the general features in the texture. You probably have to correct a lot by hand afterwards.
>>
>>656692
Thanks man, I’ve seen that one in /v/ and i dont know if i can get it to run a mac
>>656694
i dont plan to just dump it there and call it a day you dingus, i will fix seams and errors that come up.
>>656697
Doesn’t that kill a lot of detail?
>>
>>656691
Have you tried waifu2x? Name aside it actually does a good job.
>>
>>656752
As far as i know and tried, it was trained with animu pictures, wich is why it works best with non-shaded flat ilustrations. I don’t get a big difference, maybe I have to do something else

That still doesn't add information to an image when you're scaling up. You can't just take a thumbnail and blow it up to 1080p, or any other resolution bigger than the source, and expect it to not be a blurry mess. There's not enough information in the thumbnail to make an HD image from it. Same as your textures. The reason they turn out to be a blurry mess is because, fucking plot twist, there's not enough information. They're not losing detail when you scale them, they never had that detail to begin with. The reason they look good small is because they were made small.
If you want remastered textures, you have to make them at the resolution you want them to be by yourself. Plain and simple. No amount of resizing algorithms or ai is going to give information that wasn't there in the first place.

Get the offline version, it'll save you a bit of time and give you a little more flexibility. Take the upscaled result and give it a simple Sharpen pass. It won't necessarily be more high quality, but it'll definitely give you cleaner and better defined textures.

>>656774
Here's your 128x128 source passed through waifu2x-caffe. Magnification set to 8.375 so it returns a 1080x1080 result. Sure, it's far from clean and far from what I'd deem usable, but it's much different from regular scaling.
You aren't supposed to be upscaling further than like maybe 2-3x anyway. Causes a lot of mess since the NN can only interpolate that much.

In addition to what above just said, I hope to god you are not doing YET ANOTHER HALFLIFE ENHANCED LOL HDDDDD TEXTURE PACK.

That shit has not only been done to death but there are many old packs that not only did that but did proper recreations and not running textures through some shitty upscaling filters. Seriously, you at best are going to wind up with the kind of garbage seen in FakeFactory.

Oh one other thing, if you are really working on upscaling goldsrc models, many things like Waifu2X fuck up on Dithering which will make your upscales look even WORSE. If you want to "remaster" old models, learn to create textures from scratch properly or else you are going to wind up with GameBanana HIGHDEFTEXTURE PACK no 579670467#.

Here, if you want to match the old era but make some better detail this video matches that early style:

This is what I mean you idiot, use the same original pic and pass it trough AI, Its faithful to the original and better looking.
Are you retarded or something?
>>
>>656789
I’m not going to remaster Half Life. It’s just that the model has a similar quality to the ones I’m working on. Almost same era, and it looks kinda GoldSrc.
>>
>>656775
Right, but Waifu2x is meant for flat shaded stuff like the pic related. Of course it'll scale that better since it's trained to. If OP were to scale the texture in his OP image, it'd have a hard time doing that without it being a weird-looking mess. My example wasn't about whether or not it'd scale correctly in Waifu, but as scaling in general. Results just aren't going to look as good if it's not done right.

I think at max, most textures in HL are probably about 256x256 (I could be talking out of my ass here but whatever), while HD is 1024 at the very lowest and above. Even scaling that is going to have some problems. You're just not going to get details that aren't there no matter what algorithm you use.

That shit is scaled backward you double nigger.

Scaled down right side (ERSGAN) to 1/16th the size, then resized up to original using nearest neighbor filtering.
Both sides are nearly identical.

For the most part, waifu2x handles anything handpainted (without an alpha channel) really damn well. It's only when you start throwing things like dithering into the mix where it begins to falter.
But true, true, you're not going to get detail out of nowhere unless you add it in yourself. For that other anon, the ERSGAN results just _look_ detailed because a lot of these approaches throw in a lot of noise to simulate high detail. They're not necessarily detailed themselves. I'd say the results are "good enough" though.

Yeah no doubt it handles hand drawn stuff well. I've had some good results when I've needed to scale some stuff up that fit the bill, but anything photographic turned into a mess. Which is expected. The only problem I have with Waifu is once it gets past a certain point a lot of details and stuff tend to get really muddy. That and anything with somewhat more than flat shading tends to fuck up, which you said.

ERSGAN seems to work off of a dithering process more than anything else. I guess it's the same as throwing samples at a render. Though the results get finer and finer. I've seen results from it that look terrible though, because it bases things off of a realistic sense. Starts to add fur to metal and skin to water and other weird shit like that. NN has come a long way but it's not really at the point where it's more than just a novelty or something to use in very specific circumstances.

Don't worry, opengl fucks it up plenty fine on its own.

Trash in > trash out, actual texture files would work better, however there's no upscaling fucked models so it'll look shit either way.

>>656789
There are alternatives to waifu2X but the public ones are all kind of bad looking outside of certain things (what it was trained on, which is not what most retards are using it for).

try
gl_round_down "0"

Op not putting you down or anything, but to an oldfag like myself that model is ALREADY the hd remastered one, heh.

Just do what everyone else does.
