.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.

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.

one click stitch

Nice script! I have an idea request how to speed up basic stitch function. It would help a lot. Would it be possible to make stitch function working even if I stitch more than one group of polygons? Sometimes I have 60 or more pieces to stitch and only way to have best result is to stitch one by one by hand. Would it be possible?
