Creating textures


As many textures in texture archives have licenses which are not compatible with the ISC licence we will use for OpenClonk, you will have to create many textures on your own. But don't worry, it's quite easy and there are some really good tutorials on how to create quality textures from photos:

There are different methods how to create seamless textures, that's why you will find many tutorials who tell it differently. A rather good one is the tutorial on Game Artist: Create Tilable Textures. The basic procedure is to first find an eligible photo without any too noticeable inconsistencies at the border or changes in lightning / color and cut it to a square. After that, press Ctrl+Shift+O (in GIMP) to displace the image from the center. Now all you got to do is to make the seams go away, preferably with the clone brush.
Another good one including tips for how to photograph right is From photograph to normal map, how to....

Texture archives


Free / Public Domain
That the libraries are without copyright is without engagement. Most of these just don't mention any copyright, even to American law this does not (anymore) mean it is public domain. To ask the author about the license would be a good idea. So please double check by yourself.


Free with License
The most and the biggest free texture archives offer the textures free for any purpose, but it is not allowed to redistribute them as a texture pack. So, in all cases, we would need to print the license with every redistribution, in few cases where the texture comes from. As this license differs from the ISC, 3D models created with these can not be licensed with the ISC as a whole (with the textures). Thus, a OpenClonk package containing textures of these archives can not be redistributed with the ISC as a whole but has to mention these exceptions.
So if we want to make use of these textures at all is something we need to discuss. I don't see a too big problem there, though.

Nothing against this, but the "seamless tiles" function from PSP is much faster and also high qualitative.

Do you have some examples? My photoshop doesn't have this options (or I didn't find it). Is it more than duplicating the picture twice, mirror it (horizontally and vertically) and mix everything (as I saw in Gimp)?
If yes it's more or less useless. But anyhow like in most graphic issues you get more detailed and precise results by doing it manually.

PSP means PaintShopPro, not Photoshop, IIRC.

I didn't test anything with PSP. With GIMP, there are two methods: The plugin Texturize and the function Resynthesise. Both work good with textures with small random patterns like gravel, plaster, sand or ground. However, they don't produce quite as convincing results for bigger regular patterns like (roofing) tiles, bricks, wickerwork, pavements etc. as already seen on the website of the Texturize-plugin (some strawberries have become mutants).
Another example is in the attachment (first one: resynthesise, second: texturize). Original is here.

Additionally, for a high resolution (from my camera), it takes a lot of time to calculate this (up to 5 minutes on my computer) while the manual method takes about the same time when you did it a few times.

Always, there is a Programm named "Texutrehelper.exe" somewhere in the Internet, which can make seamless textures in 3sek. or faster.

Ok, this is really hard stuff =(
It's not looking good after using the effect... but is it seamless reziseable the way you mentioned above from Game Artist? It's one of the images you can't make seamless tileable.
