Forest floor materials

[MrBehemoth]

I have a question. How is the type of texture that can "repeat" called ? Like the floor/ceiling in amnesia or the one in the original post. I'd like to learn how to do that but I don't know what to research ;(

"Seamless texture" or "seemlessly tiling texture" are the words you're looking for.

What's the technique you use to make a texture tileable like that? To make it match with itself one next to another.

The best way to make it depends on what software you're using. Some image software can make tiles by blurring or mirroring, but to make it look decent you'll need to get creative with your painting/image manipulation.

Eg., I use a combination of Ps and Paint Shop Pro 9 (oldschool!). PSP has a "make seamless" tool, but it's always a bit fake looking and has glitches and artefacts, so I paint new features on top of it, copy and paste stuff, work with layers etc., until it looks right. You also need to be aware of the distribution of features. For example, if you had a big clump of leaves in the ground texture above, then you would easily see the repetition.
