Unfortunately, this version will not work properly in your current version of Blender.

damn What version would work with it?

3.9?

in 5.2 it does not even install

I have purchased the addon on blender market in 2022 and I see there is some verion 5.4.0 but when I go to download it shows me only 3.3.2

I have to pay again to get the new version?

I'll work on a fix to get everything working in your case. I can see that this is indeed a bug. Regarding the versions: at one point, we completely moved away from the old codebase and rewrote everything from scratch. The old code corresponds to Version 3 (which is your current version). For over a year, users were able to upgrade for a small fee, but that period has passed. Updating now effectively requires a new purchase.

It will take me some time to prepare the fix. However, the process can be sped up if you send me a sample scene where the error occurs. As a temporary workaround, let's return to the operator settings. Could you please show me which options are available in your version?

Sure

could we have a quick call so I can share the screen?

that will be much faster

I understand, but unfortunately that's not possible.

Okay no problem

I get this error always even whit just a cube https://cdn.discordapp.com/attachments/695620319741870150/1555902402572324895/image.png?backend=b2&ex=6ac23688&is=6ac0e508&hm=e926785287264768dcee556434e6293d432944d6137a6fe281c510d63c5bec77&

Open Operator settings and show what we have. https://cdn.discordapp.com/attachments/695620319741870150/1555902720592846878/image.png?backend=b2&ex=6ac236d3&is=6ac0e553&hm=77914a26838b4b1339f51abfb42127edca454b2b03462974596282dadc9ef86a&

Give me a little time. On my side everything is working as it should.

sure take your time Thank you so much for your help!

Also I would like to upgrade to the new version in the near future. Is there some way to get some discount since I have purchased the addon back in 2022?

I can't answer that question. Please contact @Sergey Tyapkin

Thank you.

Fixed. I sent you a DM.

Hey there, it's me again! Using Zen Uv 5.4.0 I would like to use Unwrap Inplace, and i have this error (?) when i have a "seamless" face island, and uv islands scattered over, for me it's just not "merging" together the uv island pieces. Like it's keeping the uv islands by their uv bordes, instead of unwrap along the already defined seam edges. With Zen Unwrap (so not the Inplace version), the merge is happening, but Zen Unwrap is rotating my uv island, no matter what Btw Zen Unwrap keeps the position, which is good, but then i don't understand why we have the Inplace version 🙂 I prefer the Inplace version because it has option Orientation: World Orient, but please let me know if i can keep world orient with Zen Unwrap (so not the Inplace) So question is: can i achieve somehow an unwrap that merging the selected uvs by already defined seams, and keep its position, and keep it's orientation? Thank You! https://cdn.discordapp.com/attachments/695620319741870150/1556738259265257552/image.png?backend=b2&ex=6ac540fb&is=6ac3ef7b&hm=89a814d942bf3bcb40a29a12f94cdcdc8e47e11a4a07f0a7a19d2131ec297200& https://cdn.discordapp.com/attachments/695620319741870150/1556738260796055633/image.png?backend=b2&ex=6ac540fc&is=6ac3ef7c&hm=c4c31eddf3bc70190749cf8175fb32ec7c32473897580de6da1756b90194b257&

To better understand how this works, let's break down the purpose of each operator. Zen Unwrap is a multi-tool designed for quickly splitting a mesh into UV islands. Its job isn't to track orientation, scale, or other metrics, because island packing is often used right after, which would negate any calculations made for individual islands anyway. It only preserves position and scale for convenience, keeping the UV Editor clean and manageable. Once you've finished creating your islands, you move on to using other operators like Unwrap Inplace, Quadrify, Relax, and so on. The Unwrap Inplace operator belongs to a group of tools that process existing islands. It doesn't change their count—it won't split or merge them. It only modifies their shape, position, and orientation. Wanting Unwrap Inplace to behave like native Unwrap is understandable, but doing so would cause chaos and make the operator much harder to work with, as islands and seams aren't always synchronized. We can't always rely strictly on seams, which is why all Zen UV operators—except those specifically built for splitting the mesh into UV islands—always target existing islands rather than seams. Based on this and your previous questions, it looks like you're trying to build a specific pipeline. If you share what ultimate goal you're trying to achieve, I might be able to offer better recommendations on how to effectively use the addon's operators.

Thank You for the detailed answer! At Blender 4.5 i was fine with the unwrap inplace i used that as primary unwrapping operator since it made the job done, but mostly i'm using these via python like a macro, just to configure and execute them, nothing crazy. As i'm using Blender 5.2 i'm experiencing weird anomalies, so maybe something with my install of addons not good. Now as i checked maybe i didn't install the addon properly, since via Add-ons i wasn't able to uninstall to make a clear install, and i see there are options to uninstall in the "Get Extensions" Tomorrow i'll give it a try, maybe just my install is misbehaving! Thank You for the patience so far! 🙂

You can check it as you like, but I assure you. the addon either works or it doesn't. The operators that do Unwrap are based on the native algorithm. This means that changes in it can affect the operation of the addon operators. If you notice this, let's do a test and find the error. But for this we need to localize on one operator that will be launched from the user interface.

Hi, there seems to be a UI thing: as a user, I have to manually widen the add-on panel quite a bit to prevent parts of the UI from being hidden when there are two-digit numbers of elements. Could you please look into this and see if it can be improved? https://cdn.discordapp.com/attachments/695620319741870150/1557791725739839528/1.png?ex=6ac91619&is=6ac7c499&hm=10a62c238b0f4f63169bf373aba9b4b7157516aa1c79a9958ad04192d19162ad&

We will fix it. Thank you for report
