Mesh-Library deforming mesh instances unexpectedly?

Question

Hey there I modelled two perfectly aligning wall meshes in Blender (5.0.1). One a straight wall and one curved. Exported both as glTF and imported them in Godot, set-up collisions etc. and they are still perfectly shaped in the editor.

They both fit in a 4x4 cubic volume.

However as soon as I export them as a Mesh-Library (eg Scene → Export as Mesh-Library) to use them with a GridMap the curved wall gets deformed and does no longer alight with the straight walls:

After MeshLib on a GridMap:

As you can see the curved mesh does no longer fit to the corners of the straight ones and seems to be bend. While the straight ones still match.

I couldn’t find anything online as of “common errors” regarding MeshLib deforming meshes. So I’d thought to ask here.

Kind regards, Night Crawler

Scaling the curved mesh by exactly 1.57 along X makes it fit again. Which is very weird to me. Nevermind the outside to clip, the walls are not meant to be stacked this way but you can not put two meshes on the same cell

I am soo sorry … it was me being incredibly silly … Somehow glTF does retain transforms made in blender. Where my mesh is scaled by 1.57 (bruh) but creating a mesh library out of it will reset the transforms … my bad!
