.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 ?

Currently, it is possible to render the different selected models, but rendering the elements of each model is not yet implemented.

Hi! I'm having trouble


I'm having trouble outputing an image that shows the uvshells with diferent colors for each model part.

What am I doing wrong?

stealthx, Thank for your


Thank for your suggestion. I have it actually under development.

The reason I did not release it in this version is because it is not working as it should, but I got several request to include a Stitch feature, so I included the basic version. Hopefully I will get the multiple selections Stitch for next release.

The algorithm I am working on does not support multiples shells though, but you can select several edges in one shell and stitch them at one.
