Thank you Paul.
Hm, I have two problems:
1. Multitexture workflow.
2. Probably real-world map sizes
I can't open your file at the moment but I`m guessing what have you done.
I`m thinking about splinting corners in two and use Segments Box mapping but as I remember it will not orient according to the transform rotation.
This will force me to use 2 sub materials but then this will probably break my Multitexture workflow.
Can we expect some improvement in RC color map as Browser Input and not just limited field inputs? I guess this is the major reason why people avoid it.
And some more control for randomization as "Randomise on Start/Segment/Section...."
