I seem to be experiencing an issues pretty close to this one looks like the fix should be in though, and I am still getting it. I have a NurbsCurve created in blender, and exported as an obj. my Babylon versions are: "babylonjs": "^4.2.0", "babylonjs-loaders": "^4.2.0", My loading code …

the l entry in the .obj is for describing lines. Lines that are not supported in .obj loader. Can you export without lines ? If you need lines, I think .gltf format supports it. ping @Drigax

Ah, the glb format did’nt work as it optimised the path out of existence. As a raw curve, and when converted to a mesh. It just ends up as a single empty transform node. So I tried obj, I will look at the export settings.

I just tired the Curves as NURBS option in the blender obj exporter, but still no luck. OBJ file: # Blender v2.91.2 OBJ File: 'ship.blend' # www.blender.org v 9.123311 0.000000 8.439651 v -1.995049 0.000000 8.439651 v -1.976473 0.000000 2.331339 v 4.813529 0.000000 4.435480 v 4.813529 0.000000 1.0…

FYI for anyone else trying to move just a curve over. The STL format seems to kill curves as well just like the GLB. Even when converted to mesh. If I export and import back into blender it’s just an empty object. To obj seems the way to go if Babylon3D can import it.
