Yes you can.

babylon.js requires mesh.enablePointerMoveEvents to be set to true. Otherwise, the mesh is excluded from the picking check.

github.com

BabylonJS/Babylon.js/blob/master/packages/dev/core/src/Inputs/scene.inputManager.ts#L684


      
              this._processPointerMove(new PickingInfo(), evt as IPointerEvent);

              return;

          }

          

          if (!scene.pointerMovePredicate) {

              scene.pointerMovePredicate = (mesh: AbstractMesh): boolean =>

                  mesh.isPickable &&

                  mesh.isVisible &&

                  mesh.isReady() &&

                  mesh.isEnabled() &&

                  (mesh.enablePointerMoveEvents || scene.constantlyUpdateMeshUnderPointer || mesh._getActionManagerForTrigger() !== null) &&

                  (!scene.cameraToUseForPointers || (scene.cameraToUseForPointers.layerMask & mesh.layerMask) !== 0);

          }

          

          // Meshes

          const pickResult = scene.pick(

              this._unTranslatedPointerX,

              this._unTranslatedPointerY,

              scene.pointerMovePredicate,

              false,

              scene.cameraToUseForPointers,
