Simple Bug in Blender Addon

[msamilg]

I've encountered a bug while using the Substance3DInBlender addon, and it has a simple fix.

In the function "RefreshLoadedSBSARData" in the "persistance.py" file, in line 170, it tries to get mat.name for each material slot of every object in bpy.data.objects. The problem is, if an object has an empty material slot, it will return None for "mat" (it won't skip the empty slots) and the script gives an exception and stops working because it tries to get the ".name" attribute of a NoneType object.

The exact line that breaks the script is:

sbsarIndex = bpy.context.scene.loadedSbsars.find(mat.name)

It is simply solved by continuing the for loop if "mat" is None, by adding something like this before the line above:

    if not mat:

        continue

Thanks for reporting this issue and for the detailed information on a potential fix. We will investigate this.

Hi, is this information relative with a bug from loading the correct project material with SBSAR ?

I've encountered some bugs in the latest Blender versions and the Painter add-on. Loading materials errors and a lost of the sbsar materials already configured in the blender project. Not being able to load back the previously configured materials make the use of the add-on hazardous, especially if you've deadlines. Sad. Hope this can be solved rapidly.

Hi,

Could you share more information about what Painter Addon you are talking about?
Also, could you share the logs from the Blender console/terminal?

Hi,

Painter Addon for Blender (Mac OSX 64) ver: 1.0.1

Substance integration tools 1.4.5

[Shwetha23063442qtvs]

Got it! Thanks for clarifying. The Addon is not specific to Painter. You can use any Sbsar files created using any Substance products.

Hi, I also specify that I'm running Two versions of Blender, the LTS 3.3.2 and the Latest Blender 3.4.1 -

iMac Pro, Mac OS Monterey 12.6.2

Really annoying to lose the materials, actually the Substance Add-on is running an error with Blender 3.4.1 while loading a SBSR Material, error log, => an error occurred ! In the shading tab, all the links with the images and the nodes are disconnected. The configurator sidebar isn't running as well. I've tried the solution to remove and re-install the add-on, but nothing changed.

We are currently fixing the issue where the plugin is not compatible with the latest Blender version 3.4. We'll update the website with the latest updates soon. Please stay tuned.
