Blender 3.0 Failure

[TimMensch]

Not sure if you guys are supporting Blender 3.0.0, but having installed from the Windows Store, Blender auto-updated on me and now I have 3.0.0 installed.

In any event, a scene that I was previously able to export is suddenly throwing an error:

The relevant bits are:

AttributeError: 'RenderSettings" object has no attribute 'tile_x'

This really feels like a change between 2.9.x and 3.0.0 in Blender, but please let me know if there's something that I'm likely to need to change in my scene to fix this.

Had too many change / fix / change episodes with 2.80. Only the LTS versions (last was 2.93) are going to be supported. Have gotten reports that 3.0 was working, but looks like material baking is not.

Baking is not really the best outcome anyway. You might look at the export log file and see the material being worked on & the node requiring the baking. Perhaps you might do it another way, Principled recommended. Or drop back to 2.93.

Will leave this open till 3.03 LTS goes to beta, and work begins. Thanks for reporting.

Same issue.... AttributeError: 'RenderSettings' object has no attribute 'tile-x' Is this something relating to the render method?

[Palmer-JC]

Basically, at the API level they made changes which are not back compatible.

[larjohn]

Is there an alternative to baking for things like bump maps (for instance those coming from MakeHuman clothing)?

[Palmer-JC]

Sure, bake it yourself. Not that hard to do it & worth knowing. Also, just use 2.93. You can have both installed.

[echan00]

also having the same problem, going to try 2.93 instead

[itssource]

Is this project deprecated for Blender 3.x? I see references to random posts here and there on the Internet about using this repository, but it seems development stopped at 2.9. What's the best practice today? Export from Blender for now through menu item glTF 2.0 (.glb/.gltf)?

[Palmer-JC]

Yes, there will be a version for 3.3 LTS. The intermediate Blender versions are not published for. 3.3 is in alpha. The only known bug, requiring the exporter to bake textures, has been fixed. Not sure how much else will be new / changed yet, though.

Okay, thanks Jeff.

I got the same issue when exporting my blender scene using babylonjs exporter. Here's the error logs

@ElvisWong, you may not use this exporter with anything that results in the material being required to bake, in a version of Blender newer than 2.93.

Your material 'Wall Base' has 2 nodes which have no equivalent in BABYLON PBR. MixRGB node might be added, but not Gamma. Baking in Blender also means there is going to be a texture required. Much better to use something like a Principled node for your materials, which maps much better, thus avoiding the bake / texture at run time.
