6 months ago The sample_baked function is not part of the Path3D node that has a transform or a SceneTree representation.
Thesample_baked function is part of a Curve which is a Resource.
A resource has no transform and can be shared and used by many other objects at the same time.
This is not a bug and a resource can not return the position of a node that makes use of the resource. There can be many other objects that do the same at the same time. Also a resource does not care who or what uses it because it is just (or should be) data.

Issue description
The sample_baked command returns position and rotation values relative to the created path. It ignores the position and orientation of the path. This appears to be a bug to me (when would you want a location on a path in a scene to not give you the location based on where the path is and how it's rotated?)
Steps to reproduce
Create a path3D in a child node. Instance the child node in the parent, and give the node a non zero position and rotation. In the parent, query a position along the path using sample_baked.
Minimal reproduction project (MRP)
PathTest.zip In my scene I have a 2 road tiles (nodes) that are instanced from a parent. One is at the origin and preserves the child nodes original location. The second road tile (node) is offset and rotated. In the parent I create 2 "cars" (a blue and a red CSG cube). Every frame they advance along the path of their respective road tile, and their position is set based on the results from their road's sample_baked output. Instead of each "car" travelling on its respective road tile, both are placed in the exact same coordinates as the sample_baked output isn't relative to the location/rotation of the node they're in (i.e. it's returning local rather than global coordinates and rotation).
