Help needed with maxscripting.

Hi guys!
I got huge difficulties to figure out how to write a script that can make pixel padding between the UV elements based on resolution in Unwrap UVW modifier.
I found one script from internet http://www.scriptspot.com/forums/3ds-max/general-scripting/maxscript-uv-pixel-padding which works perfect for one object selected but if I have multiple objects selected it works funny and does not keep "Normalize - off" in account.

I tried to contact the guy that made this script via email to ask if its a bug or not...I didnt got answer. I also asked almost everywhere and dont get any answer(kinda depressing), so Polycount is my last hope.
How do you guys figure out things like that? I tried to find out the logic the guy is using for the padding but I am getting lost with the variables and I cannot follow it...

Could it be possible for you guys to help me just theoretical how I could write something like that or where to eventually look for solution or examples.

Thanks in advance.

Mmh wouldn't you just have to specify the proper ratio in the unwrap.pack spacing ?
If you get the resolution of your map, let's say 2048, and want a padding of 8 pixels, set spacing to 8/2048 (0.004)

Also take a look at
http://www.polytools3d.com/polyunwrapper/index.html
It's a nice tool, and it packs by pixel. Not sure how it behaves on multiple selection tho.

It works but not always, Unwrap UVW pack is behaving very randomly, throwing the uv elements here and there.
Here is the code I am using, I am not sure if this is the optimal way to write it.

max modify mode
selObjsArr03 = selection as array
for o in selObjsArr03 do
(
select o
UnwrapMod = $.modifiers[1]
UnwrapMod.pack 0 0.004 false false true
)

Thanks for the "Polyunwrapper" suggestion but I would like to find out how I can write it. Kinda for experience too.

Anyone? I have the feeling that the array does not work well with the unwrap modifier because if I use the script on one object it works, almost but it works.

That's because you pack each object apart in your loop.
You have to share the same unwrap modifier then pack objects together.

(
max create mode
sel = selection as array
padding = 0.004
unwrap = Unwrap_UVW () --declare the modifier
for o in sel do addModifier o unwrap --add it to each object
max modify mode --force register
unwrap.pack 0 padding false false true
)
