Texture mapping

[Jaco van der Molen]

The logo on the brick is 4000x1200 pixels.
The belt is 4000x1000.
These should represent the dimensions of the planes on which they must be mapped.
Brick 1x4 is 80x24 LDU, Tile 1x4 80x20 LDU.

For use with your own custom stickers, this is fine. However, for use in an actual part, it is not a good way to do things. The texture mapping parameters can be adjusted to make the texture map smaller than the geometry it is mapped over. So texture images in official files should always be cropped to not contain any empty space around the edges.

I don't understand this. If I scale 4000x1200 pixels tot 80x24 LDU it is a perfect fit. Not?
