I have tileable texture images, which currently are 512 x 512 pixels in size. I have a texture map I'm making for a computer game which is 2048 x 2048 pixels in size.
When I bring one of these textures into gimp as a new layer, of course it fills only a small portion of the map layer.
And it's the wrong scale, because if used as-is, each leaf on a bush texture would be 100 yards long once the map is in the game.
How do I apply a texture so it fills an entire layer, and at the properly scaled size for a map like this?
