How do I create a localtoworldmatrix and worldtolocalmatrix in Godot?
In Godot a Transform3D has no concept of local or world. They are transformations between spaces, and what those spaces are depend on how you use them.
For a ...

correct matrix to draw mesh as flat object
As suggested by DMGregory, setting cullmode to none ensures that the inverted Y axis by scaling does not cull away objects. Note: It would be even better to just invert the cullmode, e.g. setting it ...
