Regarding the .net errors

Sorry for getting back to you so late, the problem basically vanished when I reinstalled a fresh version of 3DSMax '12 on top of a clean Windows, the reason for that being a very likely corrupted Max install. So I'm happily using your script again - thanks for the support!

Hey Noors, Yes, it would be

Hey Noors,

Yes, it would be possible. If your model is a mesh, it's likely an inner (invisible) edge will be the longest one in a shell, although not always.

If your model is a poly you won't have this problem. But it is a good idea to look for the longest edge among the open edges only. Perhaps it could also be to look just in the selected edges.

I will see if I that can be added for the next release.

Thank you!

Hey Would it be possible to

Would it be possible to add an option (shift+click) on the "select longest sheel edge" so the edge is only searched in the outline of shells ? I'd use this for auto aligning all shells along their longest edge. If i have a rectangle made of 2 triangles, the longest edge will be the diagonal, and i'm not interested in aligning a rectangle along its diagonal, but on one of the border. I'm beeing lil messy here but i think u get the idea. Thanks !

.Net errors

Hi man, thanks for the quick reply! I'll check at work tomorrow, it might be an AV program. I'll also check that dll's file properties. Your script works fine on my private machine and I'd love to use it at work as well ;)

.Net errors

Hi cptSwing,

Thank you for reporting this. I am looking into this the issue, but so far I haven’t been able to reproduce it.

It looks like something in your system is preventing to load the “polyunwrapper.dll” library.
Do you use an antivirus, and if so do you have real-time protection enabled?

In case you are using an antivirus, and it is flagging the library as unsafe, you can safely allow it to read/write, as the only thing PolyUnwrapper needs to have is read/write access to the installation folder. It does not read or write data outside that folder.

.Net errors, script not installing (win7x64, Max12x64)

Hey, there seem to be some installation errors in Max '12.

After finishing installation, there's a Maxscript rollout error, 'openUtility needs RolloutClass, received: undefined'

After having installed, when I load Max, the following is being spit out:

Error in Anonymous Codeblock - C:\Users\1103\AppData\Local\Autodesk\3dsMax\2012 - 64bit\deu\scripts\startup\polyunwrapper_autoload.mse; Position: 633; Line:: 6

there is also a runtime error where dotNet complains that there's been an attempt to write to protected memory.

I'm left with a Polyunwrapper folder in Users/.. but nothing in Max.

Any ideas?

Is there any way to map all the tools? I'm interested especially in the align tools.
I have some scripts for aligning the vertices up,down,etc. but don't work on multiple unwrapped objects.
I noticed that this uberscript of your does that and even works with edges and polys. I'd like to use yours but i can't acces them to bind shortcuts :)

Hi headd, What Max version do

Hi headd,

What Max version do you use?

I have disabled the soft selection for Max 2012+ because they are already integrated in the Unwrap editor, and I thought it would be confusing.

Other tools are also present in Max 2012+ but PolyUnwrapper may offer some different settings.

Soft selection is grayed out, no matter what i select or do. Any idea ?
