Hi @juniorconte and welcome to the community!
There’s ArcRotateCamera.zoomToMouseLocation - is this what you’re after?
This was discussed (and implemented) here:
Note it works for mouse wheel zoom only and not touch device pinch zoom.
Possibly your ChatGPT response was an AI hallucination ![]()
The Babylon.js team are committed to backwards compatibility, so it’s very rare and they require strong justification to remove or change any public methods in the API.
