I just tried this in Max

I just tried this in Max 2014, and am sorry to report it doesn't work :(

I know it's early days but is there anything I can to to fix this? I'm totally lost without PT in the unwrap window, I can't figure out what to do as they are in encrypted files.

I get this error when trying to run the polyunwrapper.mse directly.....

-- Error occurred during fileIn in #C:\Users\ooo\AppData\Local\Autodesk\3dsMax\2014 - 64bit\ENU\scripts\PolyUnwrapper\scripts\polyunwrapper.mse; line number: 284
-- Error occurred in anonymous codeblock; filename: C:\Users\ooo\AppData\Local\Autodesk\3dsMax\2014 - 64bit\ENU\scripts\PolyUnwrapper\scripts\polyunwrapper.mse; position: 12432; line: 284
>> MAXScript FileIn Exception:
-- Compile error: Duplicate struct member name:  value <<

and I get this error when trying to repair/uninstall.....

Anyway, just a heads up...thanks.

Hey man, regarding EricChadwick's request for smoothing-by-uv-shell, maybe you could check out how renderhjs did it in TexTools, there's an option under "Tools" (?) which I use all the time.

Amazing script! Like a breath

Amazing script! Like a breath of fresh air! Everything is simple and logical. Thank you!

My wish for the following versions: Hot keys. Support groups embedded in 2012 or create their own groups for functions rescale clusters. Will be a good addition the window of parametric moving, rotating, scaling.

Good luck in development!

Additional area

Hi, great script ! Could You add second area in "Transform" window for define a "Units"? I mean there should be two areas, one for "Units" and one for "Pixels", it would be more usefully - I think so ;). For example, we can use one "page" as "formula", so when we select some faces etc we could simple past into formula and then move it onto another pager using "Units", but after change page in different way, we could also change grid, using "Pixel", but for 8 grids, we must type-in 0.125 < and this take some time, when we must do this many times, it gets boring :/.


Sorry for my English.

Enable UV Soft Selection

I have uploaded a small script that will allow you to work with Soft Selection without unloading PolyUnwrapper.

At the moment there are no Macroscripts, but I will try to create a small installer so you can hook them to some key or menu.

Soft Selection Toolbox

 Thank you!

Two little additional tools

Hi guys,

I have uploaded two prototype helper tools featuring some functions I would like to integrate to PolyUnwrapper in the future.

As they are not final versions, many bugs are expected to occur, including script crashes, so use them with care and try them with testing models before you decide to use them in production.

They are standalone Script and can run them by dragging into the Max Viewport or from MaxScript Menu -> Run Scrip.

Normalize UVs
This is an extension of the Normalize found in PolyUnwrapper and it allows you to use custom Texel Density to normalize the UV Shells. So you can pick up the Texel Density from one model and use it in another model as well as manually modify the Texel Density and Texture Size.

Send UV Selection
This little tool will send the current selection from the Unwrap UVW Editor to the Base Model or Edit Poly Modifier. The selection can be Vertices, Edges or Faces, and it supports only Editable Poly at the moment.

There is no additional help for these tools, so you will have to experiment a little. Please don’t hesitate to send me an email or leave a comment with ideas, questions or bugs.

Both tools should run fine in Max 2008 and above.


Thank you all!!

It might be me clicking over

It might be me clicking over and over again just to increase reads counter :-). After all, perhaps the tool is not as useful as we think it is.

Regarding the videos, I too would like to create them, but I actually have not much time right now, and the little time I have to work on these stuff, I am trying to add new features to PolyUnwrapper and also finish another tool that will allow to copy UVs from one model to another (with same topology) and also between model elements.

Thank you for your words, I even didn’t know how many view this script had until I read your post.

Approaching 14,000 reads and

Approaching 14,000 reads and only 8 votes, it's a damn shame, this is top of the list in anyone's book.
I'd still love to see a video showcasing the functions, this tool has totally transformed my approach to uv-ing, but I bet I'm still missing a trick or two :)

haha okay, however in my test

haha okay, however in my test it worked alot better :D

Never get low & slow & out of ideas

Thank you so much guys...

Thank you so much guys for all your comments and ideas.

At the moment I have no plans to add the Soft Selection functions, but may include them in the future. Remember you can always unload PolyUnwrapper and get the 3ds Max tools at any time if you need to work with Soft Selections.

Great set of features. 1 and 2 I thought to implement, although 2 is quite hard.
Would you mind elaborating a bit more on the last point “Snapshot UV grid in clipboard”, because I don’t understand what it would be?

This is in fact a pending task, which I have been working on some prototypes, but could not get it working as efficiently as I want. There is a function in Max to get the Selected Geometry Edges from the UVW Modifier, but it is broken since Max 2009 (perhaps in 2008 too), so the whole task needs to be implemented via MaxScript, which makes it painfully slow. So I am in the way to find a workaround that works fast and reliable.

I am actually using the standard 3ds Max Pack algorithm.
