I think, the inheritance works only one way. If a player is attached to something, that something shouldn't get the glow effect from the player.
The idea is to modify the parachute model in 3ds max or whatever - attach a player model to it with invisible skin.
Then spawn this invisible player+parachute model as prop_physics and attach a real player to it. Then set move type to "none"
https://sm.alliedmods.net/new-api/en...EntityMoveType for the player and it will work exactly like on the video above. Just immagine the bus is the parachute.
All player move actions can be applied to the parachute via Velocity component in
https://sm.alliedmods.net/new-api/sd...TeleportEntity function. Set angle and origin to NULL_VECTOR.

https://sm.alliedmods.net/new-api/sd...OnPlayerRunCmd, convert them to velocity vector and apply to the parachute ( the same way it works with the bus).
