Tools/ materials needed:- Zmodeler and GP4Builder
- Backfires_GP4 files (.z3d files for F1 and for DTM + Textures)=
Download Link Step 1: Merge the backfire object with your F1 scene and move it until the backfire square is just behind the exhaust object.

Step 2: Once your backfire object is set correctly regarding the exhaust, hide all your objects, excepted the backfire object and the rear_light_on object. Select the 2 objects and click on Create/ Objects/ Uniteselect and click left on one of the 2 objects. Then, rename the new object as:
rear_light_on![]()
Step 3: Export your car into .gp4 format and open it into GP4Builder. On the Menu bar, click on Action / Sort car objects and save your car.
![]()
It is done! Your car is ready to use the backfire feature....
Now, into the Backfire textures folder, you will find 2 subfolders:
"With backfire" and "Without backfire"
What does it mean?:- With backfire means that you can use the backfire feature using this texture. In game, when you brake, rear_light brake and backfire will be enabled.
How the rear_light_on object work into the game? The rear_light_on object will be visible when you brake or always visible in wet conditions. What is important to know is that, in order to be visible, the alpha layer of the backfire texture must be white to be seen. All black alpha parts will not show the object in game.
"with backfire", alpha layer texture:
![]()
- Without backfire means that backfire feature will be disabled in game. In game, when you brake, rear_light brake will work but not the backfire.
"Without backfire", alpha layer texture:
![]()
In game:
"Without backfire" texture - dry conditions when you brake:
![]()
"Without backfire" texture - wet conditions, when you brake:
![]()
"With backfire" texture - dry conditions, when you brake:
![]()
"With backfire" texture - wet conditions, whatever you brake or not:
![]()
As you can see, the rear_light_on object is always enabled in wet conditions, so rear_light brake and backfire are always visible, too... you can't change this as it is coded into the source code of the game.
Maybe there is a way, for CSM mods, to use the "with backfire texture" for dry conditions and "without backfire" texture in wet conditions...
Anyway, I hope that you will like this feature and that this little tutorial will help you to add the backfire feature into your future works. It brings a little touch of realism into the game...
