Hi, I’m trying to apply a material to an imported 3d model. I made the material using 2 1024x1024 textures (diffuse and normal) but its low quality is obvious when you look it from a short distance.I saw a lot of mods that convert crappy textures in 4k huge quality textures (look at skyrim or GTAV). Is there a way to make it look like a next gen texture (The textures are from a 2008 game)? I’m quite new in this topic so I hope I’m not saying bull**** and thanks in advance for your help 
first of all you are not allowed to use/rip textures from other games in general. secondly you cant increase the quality of that hand-painted unique UV texture. so if you want a better skin, then you have to redo it and then you can have any resolution you like.
not to mention you are not allowed to share them.
Yeah, there’s no magic add detail option when trying to increase texture resolution, and textures from a 2008 game aren’t going to look good in a modern game engine, they were designed for a different time. Any automated way of up-rezing textures and adding detail, and making them UE4 ready is going to take a lot of work. There’s a GDC talk talking about what they had to do with Halo 2 assets to make them look good for the updated engine and Halo 2 Anniversary.
Oh I’m really sorry I didn’t know about that 
Thank you.Sadly I don’t have experience in this area so I think I’ll stick to tutorials to learn how to do that.
