[UV Packmaster] Efficient UV packing solution for Blender (C++ based, multithreaded)

I noticed there’s a Pro version now. How do users of Extended version update their addon to Pro? I may be missing something, but I haven’t seen any way to do that yet.

JoseConseco, I see, it turns out the UV geometry follows the different logic that the standard geometry. Anyway, we have a fix for your case and it is already available in the new version:


This release provides the new version of the add-on: professional.

The features currently available in the professional version:

Lock Overlapping: treat overlapping islands as a single island

Group By Material (Experimental): make sure islands sharing the same material are packed together. This feature is experimental: especially it can block when used together with ‘Pack To Others’ option in case no appropriate place is found for an island in the unit UV square. In such situation simply press ESC in order to cancel the process. For some UV layouts it is required to use the ‘Heuristic Search’ option in order to obtain a decent result from the grouped packing

Advanced Heuristic: use advanced methods during a heuristic search. With this option enabled add-on will examine a broader set of solutions when searching for an optimal one. As the number of solutions to check is much bigger it is recommended to use longer search times in this mode. Note that in many cases this method provides best results with ‘Rotation Step’ set to a large value (e.g. 90 degress) because such setting considerably increses the number of packing iterations which can be performed in a given time.

Why the professional version? Well, implementing advanced features for the add-on costs us a considerable amount of time. It wouldn’t make sense for us to work on this without a perspective of some additional refund. At the same time we are aware that there are a lot of people who simply don’t need such features. Forcing them to pay for something they don’t need is the last thing we would like to do. We think that introducing another add-on variant is a prefect solution to this problem :slight_smile:

And answering cadmus_sw question: in order to update from the extended version to the professional version you only have to pay the difference between what you already paid and the pro version price. So all customers who paid 15$ or more for the extended version get the professional version for free :slight_smile: Send us an e-mail with a update request and we will send you back a discount code. Make sure you send a request from an e-mail address you used for buying the extended version. The same rules apply to all who donated when downloading the basic version.

After an uvpacking a “measure area” message should be automatic so that way we keep the mouse on “pack” and click to it straight away until you get better coverage. As it is now, even thougt “measure area” button is just above “pack”, is still a bit annoying to move the mouse to click that same button after any re-packing.
Peraphs a “measure area” message could even be triggered when you hover your mouse cursor upon “pack” button?

so next will be a “superb” version followed by a “boombastic” version, etc.? :wink:
or will the pro version be the final one and additional money will be generated by additional customers?
great updates btw! :slight_smile:

Tosky, automatic ‘measure area after packing’ feature would be a nice option, I will add it to our roadmap.

actimelvanille, no no no - two paid versions is definitely enough :slight_smile: Also note that it is not like we stop developing the extended version, we are still going to add new features into it (for example I think that aforementioned ‘automatic measure area’ feature would be available for the extended version as well). Simply we don’t want people to pay for features which they don’t really need. Thanks to the pro version we can keep the extended version price lower :slight_smile:

Ah cool, great to hear @glukoz :slight_smile:
The packer is definitely worth the money! :+1:

what about to replace margin to two padding values: border padding and padding between shells?

Any documentation? Or how about a few U-Tube videos showing how to use this add-on.

Thanks, Bill

Sorry for late respone, note we are currently visiting World Cup in Russia so our responses might be delayed.

Regarding the documentation: note that all options with not straightforward meaning have wide descriptions included together with the add-on. In order to see the description of the given option you have to hover your mouse on option name for a few seconds. Same descriptions are included in the product page on gumroad.

And also if you still have any doubts you can ask a question here, I will answer as fast as possible :slight_smile:


Thanks for the response, my problem is using Packmaster for UV mapping. Its hard to find and implementation is not obvious.

Thanks, Bill

Hey just bought the pro version and it’s incredible, is there anyway of adding face overlapping detection (select faces inside islands that are overlapping) This has been missing from blender for so long and if anyone can do it you guys can lol

And also would it be possible to add margin size presets for standard texture sizes? (
256 = 2px
512 = 4px
1024 = 8px
2048 = 16px
4096 = 32px)

SilverTill, what do you mean by UV mapping in this particular case? Note that UVPackmaster is designed for UV packing, not mapping.

Way2Close, per face overlap check is something we will add in the future.

Are you using the most recent add-on release? If so, could you send us a blend file with the faulting UV layout? Thanks

Yes, im using last pro version.
Sorry can’t send you the file. But in the model around 8k uv islands and tons of overalps

Gumroad doesn’t allow me to buy the pro version because I’ve already bough extended.

Yeah, gumroad is daft like that. You need to email Glukoz at [email protected] so he can give you a discount code for the pro version. Make sure you send the request from the e-mail address you used for buying the extended version.

Thanks for the answer. I emailed him but it seems that the packmaster team is at the world cup right now and can’t answer at the moment :stuck_out_tongue:

jellbelle, thanks for reporting this issue,
I will try to reproduce it as soon as I come back from the vacation. Please consider scaling your 3d geometry to a single point and sending you UV layout - it will make debugging a lot easier.

NinthJake, I will send you a discount code as soon as possible.

Bought this last night, awesome work there @glukoz Thanks for this addon. :grinning:
