I had the same Issue, but

I had the same Issue, but it's not related to this script.
Basically you just have to Assign another key to this command. Sadly Space doesn't respond well for shortcuts.

Autodesk bug - shortcuts

The bug related with hot keys in the unwrap window is old at least three years. I used to use spacebar to "Select By Element UV Toggle" a lot. But today in three last versions of 3ds it works only if you are out of unwrap window focus (click in the 3d viewport).

This bug as a present from autodesk slow down work a lot! Maybe everybody should report this to the autodesk and maybe in next update or next few years it will work again.

Thank you for such a great script!!!

Up/Down keys issue

Hi Headd,

I have run into this same problem and also received a few emails reporting the it.

It seems it is a Max related issue and has to do with how Max handle the Tab Controls, at least that is how it looks to me.

If you make the selection in the viewport instead of the Unwrap Editor, then the keys works fine, but as soon as you focus (click) on the Editor or a rollout (even in the Unwrap Modifier panel) Max takes control of the Up and Down keys and use them to tab between the different controls, similar to using the Tab key.

Unfortunately I do not see a fix for this, and would be glad to know if someone has a workaround.

Regarding the rotation, the current function does rotate around the center of the Shell, but what you mention makes more sense, so I will see if I can modify it to rotate around the pivot, and perhaps keep the rotation around center hocked to Ctrl key.

Thank you!

Great, saving settings and macro shortcuts are working :)

- A small problem, though, when I decided to assign rotate/mirror to ctrl+arrows.
The ctrl+up/down arrow doesn't work here, no action was recorded, as if nothing happens. Also happens if assing the script to plain up/down arrows, no modifiers (eg. ctrl)

- Another thought. Right now, the rotation is based on the selection center, not the actual pivot, because if i move the rotational pivot to a corner, the shells will rotate from the selection center.

Otherwise, congrats for the script. It's a must have.

Pixels per metre

Hi mawilbolou,

PolyUnwrapper does not have such a feature built in, but I have another tool that does what you are looking for, and also has a few other functions. Check it out here:


Note that the Texel Density is based on the texture size, so if you are using different textures sizes you would need to select the models separately. But you can select a group of models that share the same texture resolution and normalize all of them at once.

Pixels per metre

Hi there...

Cool script..

It would be great to select a bunch of geometry, apply the unwrap modifier,
Set the pixels per metre (EG 128 PPM) and unwrap it to that scale...
Is that possible with PolyUnWrapper?

If not it would be a amazing addition! and every game artists dream!

PolyUnwrapper v2.5.1 - Update

What's New

- Fixed MacroScripts not working in Max 2012-2014
- Fixed PolyUnwrapper Settings not saving properly

Unfortunately there is no fix yet for the slow down when Gamma/LUT is enabled or using 4k or larger textures in viewport.

Thank you all!

"Did you look under the PolyUnwrapper category?"

Weird, I don't see that either, I always thought it was controlled via the Maxscrit/Utilities dropdown in the Utilities Tab.

Just checked.....if you move ...

C:\Users\xxx\AppData\Local\Autodesk\3dsMax\2014 - 64bit\ENU\scripts\PolyUnwrapper\scripts\polyunwrapper.mcr


C:\Users\xxx\AppData\Local\Autodesk\3dsMax\2014 - 64bit\ENU\usermacros

then you should see the PolyUnwrapper Category, I didn't even realize they were their either.

cool :)

hope this helps.

Thank you guys for the feedback!!

Thankfully I was able to reproduce the bug you mention. As far as I could see, it only happens when switching between modes and if you have Gamma/LUT enabled. I could not see any general slowdown in other areas, but I will try to fix it soon.

Regarding the MacroScripts, I can’t reproduce what you are experiencing. The new MacroScripts are located in the same file as the MacroScripts that open the PolyUnwrapper toolbar “polyunwrapper.mcr”, so I would think if the toolbar is working, the MacroScripts should be visible. Did you look under the PolyUnwrapper category?

The other issue is something I have to do a quick fix. Actually, the “Save All Settings” should not close the Settings Dialog, but display a message instead, something like “Settings Have Been Saved”. The way they are working now is annoying and confusing.

Hope I can release a quick fix soon.
