### Issue description

When creating curved Path3Ds and using the Option `Debug > Visible Paths` they don't show up curved and instead are just straight lines.
Source Code: https://github.com/Arbee4ever/Train-Game/blob/master/scripts/World.gd#L115

1. Create Script to create curved Path3D
2. enable `Debug > Visible Paths`
3. run game
4. see straight line instead of curve
