The transparent control points should simple enough, I can just add some more settings into the settings tab for that (if there’s anything else you think should be configurable as well please let me know).
Parenting paths to anything other than the _Path3DEditorPaths isn’t currently supported, but could elaborate on why you need paths parented to something other than _Path3DEditorPaths? Unless if you have a very specific use case, the paths that the editor uses are only for visual purposes in studio and they aren’t used at runtime, only the path string is. Without knowing the specifics of your use case, what I would say to do would be to have a StringValue parented somewhere in your level in ServerStorage, and then link that StringValue to the path so that whenever the the path string is regenerated, it will automatically update with the new string. From there you should be able to just use Path3D.fromPathString(STRING_VALUE.Value) to make a Path3D instance. If this doesn’t work for your use case though please let me know.
