Hi... I am new on this forum and came here just because I have encountered unsolvable problem with UVW unwraping.
Ive done this process a lot of times before but this time I have major problem.
Ill try to describe problem:
I have facade of building, with multiple objects attached as one (wall, windows, window glass....)
When I try to unwrap it with "Box" and align it, bounding box of unwrapper is off center (skewed) and cant find way to fix it.
If object (thing beneath every window )is Detached like in next photo and UVW unwrap is applied with "Box", same thing happens:
Whole building is built from rotated box because i had to match everything to camera (Im using photo as reference).
Had some bounding box issues in process that couldnt be fixed with "reset Xform" but only with script (which crates box using autogrid on object with bounding box problem and aligns its bounding box with with one of the box created - as I could understand it
)
I have deadline so I need help soon as possible. I could send *.max file if someone could help with it.
(sorry for bad english)

This facade is only 1/5 of front side of 1/5 buildings
I am planing of unwrapping separate objects because I have exterior/interior walls and generally lots of stuff (Im planning to render everything in glass material with vray)
I NEED HELP ASAP!
Is your object rotated in the world ? You need to get it aligned to the world axis then apply a Reset Xform.
If ever you've reseted xform after the rotation and have no longer the initial angle, you could snap an object to a face with autogrid to get the angle.
Wierd thing is, when I had single window, UVW align was still off axis but after copying windows, wielding vertices between them and again detaching one window I have regular aligment in UVW.
Also, diffuse map is different so as I see it, my only way is to unwrap one window, copy it few times, align them so there are no intersections and group them, align UVW map for whole floor. But I think that Ill have problems with seams on intersections so I dont know if I should wield vertices between windows after aligning. Will that destroy baked UVW map on every window?
p.s. i am familiar with UVW crap but never had big project like this, its whole street with 7 buildings including interiors.
