The NFS 4 dashviews can be quite complicated when going for a higher detail level with lots of small details. Here is a tutorial on how to name these parts and how to sort these correctly, in order to avoid visibility problems.
The _[X] things like _PM, _L and _W are special parts. _PM and _DM are the mirrors, they have to be shiney so by naming a part e.g. ":F :L_PM PassengerMirror" NFS knows it has to be displayed when looking forward and to the left and that it has to be shiney. The view attributes like :F :B :L :R :S are added in front of the part name with a space between and no underline.
The _PM.. attributes are added directly behind the part name without a space. After _PM, you make a space and type a part name. So basically it's like this:
|:F(space):R|_Attribute|(space)Partname|
Sides:
:F Visible when looking forward
:L Visible when looking to the left
:R Visible when looking to the right
:B Visible when looking backward
:S Function is unclear.
- all view attributes can be combined, they can be sorted any way you wish to.
Attributes:
_PM Passenger mirror (reflective)
_DM Driver mirror (reflective)
_W Steering wheel
_L Lit dash

Include the _PM or _DM attribute to body parts visible in your dash (e.g. front fenders, spoilers, hoods etc., but if you do that you should not use the mirror parts (:OLM, :ORM) on the exterior because when wrecking your car, the mirror parts will disappear in the exterior view and in the dashview - so all _PM and/or _DM parts are gone. So fuse the mirrors with the :HB.
Dashview parts have to be sorted in the opposite visible order. Your steeringwheel is in front of the roof, so put the roof at the top of the list, and the steer somewhere under it. A good hint for the part order are EA dashes, but careful, you gotta detach a LOT of parts in order to get the correct visibility. Just as another hint: Our cars dashviews have up to 40 parts or even more!
Additionally, NFS:HS crashes when you use more than 67 parts.
