Objects in the gp4 car

You should know that all the cars in GP4 have the wheels at the same position, so we can't move the original position of the suspensions and the brake disk because if we move the suspensions the wheels will be in an incorrect position.
We can modify the cockpit because we can adjust the position of the helmet and the steering wheel with Team Editor (it is explained at the end of this tutorial in the get the car in game section).
Moreover you can modify the position of all the other objects of the car.

The order of the objects in a gp4 car is very important, and you must have all the objects in following order:

objects in car_myteam_car1_lod_0.gp4

• cockpit
• engine
• f_l_brakeglow
• f_r_brakeglow
• left_barge_board
• left_front_fin
• left_front_suspension
• left_front_wing
• left_rear_fin
• left_rear_suspension
• left_sidepod
• lower_rear_wing
• nose_cone
• r_l_brakeglow
• r_r_brakeglow
• rear_light_on
• right_barge_board
• right_front_fin
• right_front_suspension
• right_front_wing
• right_rear_fin
• right_rear_suspension
• right_sidepod
• upper_rear_wing
• z_cockpit_insert
• z_cockpit_left_mirror
• z_cockpit_right_mirror
• z_cockpit_visor

A gp4 car has 5 lods (you can see it in the cars.wad). These lods are:

• car_myteam_car1_lod_0.gp4
• car_myteam_car1_lod_1.gp4
• car_myteam_car1_lod_2.gp4
• car_myteam_car1_lod_3.gp4
• car_myteam_car1_lod_4.gp4

The lod_0 is the most detailed shape and it's used when you see the car in a short distance. And the lod_4 is the less detailed shape and you can see it in the mirrors for example.
The objects for the other lods are:

objects in car_myteam_car1_lod_1.gp4
car_myteam_car1_lod_2.gp4
car_myteam_car1_lod_3.gp4

• cockpit
• engine
• f_l_brakeglow
• f_r_brakeglow
• left_barge_board
• left_front_fin
• left_front_suspension
• left_front_wing
• left_rear_fin
• left_rear_suspension
• left_sidepod
• lower_rear_wing
• nose_cone
• r_l_brakeglow
• r_r_brakeglow
• rear_light_on
• right_barge_board
• right_front_fin
• right_front_suspension
• right_front_wing
• right_rear_fin
• right_rear_suspension
• right_sidepod
• upper_rear_wing

objects in car_myteam_car1_lod_4.gp4

• cockpit_low

We will edit the lod_0 and when we finish it, we will delete the z-objects(z_cockpit_insert, z_cockpit_left_mirror,z_cockpit_right_mirror, z_cockpit_visor) and then save as lod_1, lod_2 and lod_3.
Finally we won't edit the lod_4, we only will remap it (to see the correct colors of the car in the mirrors).


To finis this section I'm going to tell you a good trick to save time in ordering the objects in a gp4 car.
To order the objects names of our car in a easy way:

Type the objects name in zmodeler (all the objects but not in alphabetical order).

Now export the car in .gp4 format.

Load the exported car in 3Deditor ( www.realgpx.com).
Then go to Action -> Sort car objects and the objects will be ordered in alphabetical order automatically).


Save this file.

Finally import the saved gp4 file in ZModeler and you will see that the objects are in alphabetical order.
To finisht save as ordered_car1.z3d in order to can export later the lod_0, lod_1, lod_2 and lod_3.

This method saves a lot of time ordering the objects in ZModeler. It's really good.

Thanks Dahie to told it to me.
