Error with Blender Files: BLEND_BMESH: BMesh uv loop array has incorrect size

[tmason101]

Hello,

I get the error when trying to open any Blender files:

BLEND_BMESH: BMesh uv loop array has incorrect size

Do I need to send the files to anyone for this to be checked out?

Opening Blender files would be a huge plus :)

Thank you.

Yes, this is actually a really big issue right now. In production builds, I've completely disabled usage of the new BlenderBMeshConverter code path, as it fails for many of the .blend meshes I've tried. My vote is to temporarily disable that path until we can figure out what is going wrong, thoughts @acgessler ?

[tmason101]

Kool, at least I am not the only one :)

Is this something that will take a while to fix?

[acgessler]

@jdduke I'm out of the loop on that. What's the relevant issue numbers?

[jdduke]

Hmm, there's #373, #318 (possibly unrelated), #315 and #132.

[acgessler]

Thanks! Agree, we should temporarily disable the code path.

[tmason101]

Any line or section to comment out in particular?

What temporary changes?

Also, would love to help for a long term fix; I'm an intermediate C++ developer...

[jdduke]

I'm not super familiar with the BMesh conversion code, but you can find the relevant code in the BlenderBMesh and BlenderTesselator files.

Is this issue still open?

You can open Blender files with ASSIMP now thanks to the fix; not perfect but I am crossing fingers that things will be improved in the coming weeks.
