UV Manipulation is broken in Blender 5.0

[Aybex]

Hi,

With the update to the UV Editor in Blender 5.0, almost none of the UV Manipulation tools of Textools work anymore.

Python: Traceback (most recent call last): File "C:\Users\Ayoub\AppData\Roaming\Blender Foundation\Blender\5.0\scripts\addons\TexTools-Blender-master\op_rectify.py", line 37, in execute utilities_uv.multi_object_loop(rectify, self, context) File "C:\Users\Ayoub\AppData\Roaming\Blender Foundation\Blender\5.0\scripts\addons\TexTools-Blender-master\utilities_uv.py", line 27, in multi_object_loop func(*args, **kwargs) File "C:\Users\Ayoub\AppData\Roaming\Blender Foundation\Blender\5.0\scripts\addons\TexTools-Blender-master\op_rectify.py", line 49, in rectify faces_loops = utilities_uv.selection_store(bm, uv_layers, return_selected_faces_loops=True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\Ayoub\AppData\Roaming\Blender Foundation\Blender\5.0\scripts\addons\TexTools-Blender-master\utilities_uv.py", line 125, in selection_store if loop[uv_layers].select: ^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'BMLoopUV' object has no attribute 'select'

Looking at the Blender API docs The bmesh.types.BMLoopUV.Selec have been removed in the 5.0 API

• 4.5 API
• 5.0 API

Change confirmed in : Release Notes article

The UV selection is now shared between all UV maps.

Added:

The following UV attributes have been added.
    .uv_select_vert (face-corner).
    .uv_select_edge (face-edge).
    .uv_select_face (face).

BMesh attributes:
    bmesh.types.BMLoop.uv_select_vert.
    bmesh.types.BMLoop.uv_select_edge.
    bmesh.types.BMFace.uv_select.
    bmesh.types.BMesh.uv_select_sync_valid.

BMesh methods:
    bmesh.types.BMLoop.uv_select_vert_set().
    bmesh.types.BMLoop.uv_select_edge_set().
    bmesh.types.BMFace.uv_select_set().
    bmesh.types.BMesh.uv_select_flush_mode().
    bmesh.types.BMesh.uv_select_flush().
    bmesh.types.BMesh.uv_select_flush_shared().
    bmesh.types.BMesh.uv_select_sync_from_mesh().
    [bmesh.types](https://docs.blender.org/api/5.0/bmesh.types.html).BMesh.uv_select_sync_to_mesh().
    bmesh.types.BMesh.uv_select_foreach_set().
    bmesh.types.BMesh.uv_select_foreach_set_from_mesh().

See the bmesh.types API docs for details

Removed:

The following UV selection properties have been removed:
    bpy.types.MeshUVLoopLayer.vertex_selection.
    bpy.types.MeshUVLoopLayer.edge_selection.
    bmesh.types.BMLoopUV.select.
    bmesh.types.BMLoopUV.select_edge.

Does anyone know the current maintenance status of this repository?

If there is no activity within the next few days to weeks, I plan to take action myself, as many people (including me) rely on this critical repository.

(I don't intend to take full ownership, as that would be disrespectful to the original author and a significant burden. Instead, I think I will just spearhead the effort to get it working in Blender 5.)

(To be honest, rather than me taking half-baked action, I think the most reassuring solution for everyone would be if a contributor familiar with the add-on's history could take over maintenance.)

[Aybex]

It looks like the repository's last activity was in November/December of last year regarding Blender 4.3 fixes, but the author seems to have been inactive on GitHub since then.

I've tested your commit, and most of the functionalities work great. I'll try contacting the maintainer off-platform to see if we can get these changes merged. If not, we should at least try to update the README to point to a new fork

[unclepomedev]

Thanks for looking into this!

The author hadn’t been actively maintaining the repository even a year earlier, so I ended up creating my own add-on, a Lite version of which can be downloaded from Extensions.

A lot of things were originally taken from TexTools and then heavily improved and refined. On top of that, many new operators were added.

Of course, I don’t want to abandon TexTools either — its baking system is very convenient. But a lot of the features I need no longer work there. If the repository’s author were active, I might have been able to fix those issues.

[unclepomedev]

Thanks for the info! I was actually aware of your add-on and had it on my list of potential alternatives, though I hadn't had the chance to test it extensively yet.

Hearing that you've refined the underlying code and improved the operators makes it a very compelling option. While TexTools still has its merits as you mentioned, it might not make sense for someone to try and maintain the old UV features if you've already built something better.

For anyone who still really wants to use TexTools in Blender 5:

It seems to work (at least regarding the issue discussed here) if you apply the changes from PR #271, zip up the files, and install them from disk.

If you don’t want to patch it yourself, I’ve also published an unofficial zip that’s just TexTools 1.6.1 plus the changes from PR #271 applied:

https://github.com/unclepomedev/TexTools-Blender/releases/tag/v1.6.2

Use it at your own risk, and please note that it’s not an official release from the original TexTools authors.

[unclepomedev]

Glad to hear that!

I checked the extension available via #271 - it doesn't seem to have the Baking functions.

Does v1.6.2 have working Baking?

Appreciate all the efforts keeping this great addon alive.

Thanks...

[unclepomedev]

Thanks! Unfortunately, v1.6.2 doesn't cover the Baking fixes yet. The code base is quite complex, so fixing the Baking system will take some time.

It is on my todo list after I finish my own work. If you could open an Issue on GitHub with the specific error logs (from the System Console) you are getting when trying to bake, that would be very helpful for future debugging.

[scottb613]

Thanks so much for taking the time and the response.

Yeah - I'm sure it's difficult - I'm hooked on basically - one click - baking.

Will do.

Happy Holidays to you and yours.

[unclepomedev]

@scottb613 I've just uploaded a new version (v1.6.3) that should fix the Baking system.

It was a bit of a "whack-a-mole" game with the errors, and while it seems to be working correctly on my end (I confirmed the Tangent Normal baking and UV Mesh morphing), I'm not 100% sure if I've covered every edge case. 😅

You can download it here: https://github.com/unclepomedev/TexTools-Blender/releases/tag/v1.6.3

Could you give it a try when you have time? I'd appreciate it if you could verify if it works for your workflow as well.
