Hi.

I need more free seamless textures, but don’t know where to get them.
If you can help me out, please do.

Thanks, but that’s not quite what i meant.
I need seamless textures as a single jpg or png, with all the properties and colors in one file. For use on web pages as tiled background, as part of my free framework GitHub - nicerapp/nicerapp: this is a revolutionary and constantly evolving, well-maintained repository of HTML, CSS, JS and PHP code with which you can build websites that use a tiled image, photo or youtube video as site background for information and apps that are put over that background in a semi-transparent way.
Is there a way to do this for the link previously mentioned in this thread? I’m new to 3D tools like blender.
