Yes! You can bake the texture channel of an object to an image and then save the image. However this output is not seamless, it is a static image (Blender just bakes what is visible) so once you bake it, you cannot procedurally change the size anymore.
Anti-tile works with any engine that uses cycles nodes for materials.
Currently this includes:
- Cycles (2.79 + 2.8)
- Eevee (2.8)
The Anti-tile script to create Anti-tile textures is only guaranteed to work within blender. Therefore if you wish to use it in other engines you will need to apply Anti-tile in blender and then export out the material.
Since Anti-tile makes use of procedural noise and complex mapping, the final result can only be seen in rendered view. Textured view will still display regular tiling.
