Hello,
I've recently got into AI upscaling, after trying out all the "free" ones alongside with some of the projects on GitHub, I've ended up using Let's Enhance, which is pretty pricy to be used for upscaling multiple UV textures, since most characters have atleast 3-4 textures per material, and around 6-9 material surfaces per character.
As a sample, I've upscaled Jenni 8's torso diffuse map from the default 4k to 8k and 16k, mega links here:
16K
8K
4K(Stock)The algorithm I used introduced some changes to the color, like the color becoming a tad darker, but it's more than useable for characters and props alike.
So point being, if you have an asset with low texture res, you might have a chance to make it look better than before, but do keep in mind; even AI can't make quality out of thin air.
Any thoughts? Good or bad?
looks good to me. but textures got super sharp and normal map is going to mess.
As you said this helps with low textures res. good work.@Aitha Obviously all of the maps will be upscaled if needed, it's not limited to only diffuse maps, if that's what you meant.
@cptalexx yeah, I know that. can you share 3d model render with 16k textures? I want to see the difference between 4k and 16k.
@Aitha I dunno if I can do that, takes multiple gigabytes of VRAM to render a character with only 16k textures, but I can do something small later today
In these samples I only upscaled all the face maps, I didn't touch the lips, in the stock 4k renders I think I accidentally added a normal map for the lips which seems to be missing from the 16k renders.
The resolution doesn't matter from longer view distances, might even make it look worse, but it's meant for closeups.
But like I said in my original post, it's mostly useable only on models with lower res textures, like 1-2k, instead of upscaling already good looking textures like 4-8k 🙂
@cptalexx thanks a lot and they look great. close up shots are awesome. but VRAM is going to cry. Thanks for your time. have a nice day.
