There were several threads about this - [Detecting position on surface of mesh after moving a point in mesh on a certain direction by a certain amount](https://forum.babylonjs.com/t/detecting-position-on-surface-of-mesh-after-moving-a-point-in-mesh-on-a-certain-direction-by-a-certain-amount/18055) and [Ride on surface of mesh](https://forum.babylonjs.com/t/ride-on-surface-of-mesh/7960)  
Some PGs from there may help.
