Why does my Mesh in the Scene not line up with the one in the Preview?

Godot Version

4.3

Question

I am trying to create a simple prototyping MeshLibrary for a GridMap. But every time I import a model, Godot changes the dimensions of the model. I know it isnt a problem with my version or installation since I have a scene from a Tutorial that works. But if I try to make my own simple models they always get stretched in a weird way. What do I need to do to correct this problem?

You need to apply your transforms to the mesh.

A mesh Resource has no transform, e.g. rotation, scale, as a transform is part of a Node3D, not the Resource.

So what needs to happen is that all that transform information gets baked to a new mesh. Select the option to apply all transforms on the MeshLibrary export.

Thanks
