I am creating a model to be rendered with a number of different wallpapers. The problem is that for each piece of paper on the walls, a small offset is needed to make the pattern in the wallpaper to match.
I therefore model the walls as a number of planes that are as wide as the wallpapers are (53 cm) and as high as the wall is (3.5 m). I then texture each plane with a wallpaper image that is square (512x512 pixels).
The etxture repeats good in the V direction (up), which is exactly what I wanted (using OrCo:s and SizeY to 6.6) The problem becomes visible when I try to offset the texture of the second plane:
As You can see, the textures also repeat in the U direction (sideways) and therefore (because of filtering) causes some of the texture on the left side of the texture to wrap around and also be visible on the right side.
I would therefoe like to use Extend in U direction and Repeat in the V direction, but that is not possible since You only set it once and it applies to both U and V.
What can I do? Am I missing something? Does anyone understand whatI amt trying to achieve ? .
