Import fails - Blender 3.4 removed use_customdata_edge_bevel mesh property

[shugosmail]

Hi,
can you please update plugin to work with Blender 3.4 and newer? Blender recently removed use_customdata_edge_bevel
Here is more information about Python breaking changes in 3.4:

Done, see latest release.

Hi and thank your for your quick response. I tried it and import now works without crash but there's still some issue with bevels

Blender 3.3.1 ImportLdraw 1.1.11 (2465 objects, 27.5M tris, 15M faces)

Blender 3.4 Beta ImportLdraw 1.1.13 ( 2465 objects, only 9.9M tris and 6.3M faces )

Both scenes were imported with the same bevel options

[grahamwheaton]

Same issue for me

[shugosmail]

@TobyLobster Hi, could you please fix also the bevel options as mentioned above? Thank you very much.

[TobyLobster]

Fixed in latest release

Hi, I tested it on version 3.4.1 Stable (build from 13.1.2023) and it's still not working.

I also tried to use blender 3.5 and import dosn't have Bevel edges.

[TobyLobster]

Perhaps you could try installing this version as a test:
importldraw1.1.15_without_background_exr_for_blender_281.zip
If it works I will make a proper release.

[shugosmail]

I also tried to comment out mode_set before but then I started having this error log ( and i dont know anything about blender python API so i could continue experimenting :D )

[TobyLobster]

Ok, I suggest the original version is the correct version. Perhaps there is an issue importing a specific model? If you can open other models ok then send me one that doesn't work and I can look at it. When you import do you have a 3d viewport visible? (It may have problems if you don't).

[shugosmail]

Yes 3D viewsport is my default view.
It generates erros on whatever model I choose (different builds of Blender 3.4/3.4.1). And same ldr file worked in 3.3.1 using previous version of importldraw. Here's is the smallest example I've got. Can you reproduce my errors with this?
Wall.zip

In Blender 3.5 I don't get error with enum EDIT mode not found in but there are still bevel edges missing.

[TobyLobster]

Seems to work here (Blender 3.4.1). Weird - I don't know why this isn't working for you. Is there some configuration difference maybe??

[shugosmail]

Really weird hmmm. At least it works for me in Blender 3.5 but still, I can't get bevel edges working. If you zoom in your picture above, do you see bevel edges working?

[TobyLobster]

You're right, I don't see the bevelled edges in an up close render. I don't know why they are not appearing though, since the Bevel modifier is present (see screenshot), and sharp edges are present (you can select them in EDIT mode). So why are they not rendering?

[TobyLobster]

They are not getting the custom weight data, I'm investigating...

[grahamwheaton]

Thanks for trying to fix.

Yes same problem for me with Blender: 3.4.1

All the edges that should be Bevel weight 1 are marked as 'Sharp' and 'Bevel weight 0'

Blender 3.3: (Working)

Blender 3.4:

[TobyLobster]

Should be fixed in latest release https://github.com/TobyLobster/ImportLDraw/releases/tag/v1.1.15

[shugosmail]

Just tested, works in Blender 3.5. Thank you!

Hi,
I installed the addon v1.1.15 in Blender 3.5.1 and there is the error again.
AttributeError: 'Mesh' object has no attribute 'use_customdata_edge_bevel'

It works fine in Blender 3.5.0

[Michuklon]

hi, I tried to use this addon, but it doesn't import any Lego pieces, just empties. why is this happening?https://i.imgur.com/EuchAY4.png
I followed every step

[dvell]

Hello, I installed the addon v1.1.18 in Blender 3.6.1 and unfortunately getting the error too:
