Resolution of intersection texture in UC-win/Road is 1024 pixel by default,
and 2048 pixel when creating in high accuracy. Although the upper limit
is 4096 pixel, intersection in 4096 pixel cannot be made so much because
the data of a vast detailed terrain is easy to be the memory shortage
as well as affects the data capacity. In 64 bit version, users can use
high resolution textures without worrying about memory, and quality of
appearance will be guaranteed even at large intersections.
It is not possible to generate a texture more than 4096 pixel on the texture
editor screen, but textures of 8192 pixel is available by converting an
intersection to a 3D model.

High-resolution section texture
Road textures and textures used for road sections like guardrails and sound
insulation walls are usually set to repeat 1 to 2 meter square textures
or 4 to 10 meter vertical (horizontal) textures. However, some texture
patterns may cause a feeling of strangeness by being able to be recognized as
the same texture repetition. In that case, the appearance will be more
natural by pasting a very long texture of 60 to 100 meter long that does
not repeat the same pattern.
Quite a high-resolution image is required to keep the accuracy of appearance,
and the 64 bit version can support this without any problems.

High resolution textures are often used for terrain textures, aerial photos,
sky domes in addition to intersections and sections. In the case of sky
domes, a very detailed and delicate starry sky like the image below
can be drawn by creating a texture of 16384 pixel.
