Let me get straight to the point.
I would like to know if there is any pipeline, or any method to be used in refurbishing low resolution textures. What I would like to do is: I have a few 512x512/256x256 resolution textures, and I would want to make them 2048x2048 or even 4k, of course with the added detail, not just resizing them in Photoshop.
Now I know the question is kind of a dumber, but still what steps would you take, if you wanted to do the same? I didn’t really find any good resource on this topic (which may be a sign there is no real way of doing this…).
PS: Some background: those are textures from an old game, and I am porting it to a modern engine.
An example of a texture I want to refurbish is one like this:
What approach would you take to make it 2048x2048?
Thanks for your input,
