Working with Forza Apex car models.

Version 3.1h of 3DSimED can import car models from both carbin and modelbin formats.

Preparing For Import

Before importing is is very important to have decompressed the .zip archives which store the resources for the car models. The quickbms program does a wonderful job of extracting the files but, there is a problem. When used to process a folder tree of .zip files, the folder tree created by quickbms is not correct.

To overcome this limitation batch files and a Powershell script can be downloaded:

  • The simplest option is to use the batch file unzipCars.bat. This batch file skips the tracks which, at present, cannot be imported with 3DSimED.
  • Open the batch file in an editor such as Notepad and change the source (game folder ) and destination folders so they are correct for your system (in Notepad you would use the Edit->Replace function).
  • If you cannot find the source folder you should make sure that hidden files are switched on in Explorer and then look for the WindowApp folder either in C:\Program Files\ or the root of the drive on which Apex was installed.
  • In Explorer, with the shift key held down, right click on the WindowApp folder and open an Admin Command Prompt. From that command window you should be able to see the full folder name for the Forza Apex installation.
  • The second batch file, unzip.bat  will decompress the cars and tracks.
  • The Powershell script will generate a batch file, this is useful when the Forza Apex content has changed or to unzip another set of .zip files such as those from another Forza title.
  • At the time of writing, the permissions to execute a Powershell script are switched off by default in Windows 10. A quick search will reveal how to enable permissions .
  • The Powershell is intended to help out please feel free to improve it and offer it to to others


Importing Forza Apex Car Models

With the Forza Apex resources decompressed and in the correct folders it should then be possible to import .carbin and .modelbin.

  • The .carbin files define a car while the .modelbin files are the components of the car.
  • The .carbin files contain addition material definitions so even when editing a single component for a better result open the .carbin and then isolate the object to edit it.
  • Many materials in Forza Apex appear to use procedural shaders and do not have diffuse texture maps. To help with compatibility  with other sim formats, solid color texture maps are created as the diffuse texture maps, for example,

Below is an example of how a Forza Apex car model should appear in 3DSimED3. The file imported was MAZ_70_B1280_14.carbin


Working With FH3

Forza Horizon 3 files from a dump can be unzipped easily because there is no encryption but the filenames look very strange.

A Powershell script and example batch file can be downloaded here , the script and batch file use 7-zip to unzip.

After unzipping the files will need a renaming utility to process the filenames and when finished the layout and names should resemble those from an unzipped Forza Apex.

Apex/FH3 Materials & Textures

The files from a car folder are not enough to correctly import a .carbin. Many of the materials (.materialbin) and texture maps (.swatchbin) are located in the cars\_library folder tree.

The image below is the result with only the car folder:

FH3 1965 Cobra only car folder

With the full set of files this is the result:

FH3 1965 Cobra Full file set


3DSimED3.1i Released

Version 3.1i includes improved support for rF2, and adds Forza Horizon 3 Import.

Studio 397 have included a few new shaders in their release of rF2. These shaders are now supported by 3DSimED3 it should be possible to export models using these shaders. However,  please understand that as 3DSimED3 remains a D3D9 application you will not see the same quality rendering in 3DSimED as in the DX11 rF2.

FH3 Woody Ford

Support has been added to import Forza Horizon 3 cars. Also, for both FH3 and Forza Apex Import the user can now choose the LOD to import.

Note that 3DSimED3 cannot automatically detect the difference between Apex & FH3 Carbin so please make sure the correct format is chosen from the drop-down box on the Import dialog.

Visit the download page for new version.


3DSimED 3.1h Released

Version 3.1h is released with support added for Forza Apex car import. Complete cars can be imported (.carbin) and individual components (.modelbin).

Apex 2017 Ford GT EcoBoost

Please note that tracks and track objects cannot be imported.

Clone Object has been added to the Object Instance Edit Pane.

The rendering of cube map shaders has improved, drag rotating a drawing should be faster,  Import Collada DAE support is better and more Forza Apex SwatchBin formats are supported.

Windows 10 users have had problems on AMD graphics hardware due to changes made in the Windows driver, 3DSimED now has less screen tearing than before.

There are also fixes for exporting to PNG, corrections have been made to the order of the SearchPaths in scenes and to the bone positions in an rF2 .GMT when a pivot point has been set.

Visit the download page for new version.

3DSimED 3.1h

New: Support for importing Forza Apex car models, both .carbin and modelbin can be imported. Only cars or car components can be imported, tracks and track objects cannot be imported. Note that although most Forza Horizon 3 car modelbin can be imported the carbin files cannot.

New: Clone Object has been added to the Object Instance Edit Pane. This function creates a new object which is copy of the presently selected object.

Enhanced: Drag rotating a view should be faster.

Enhanced: Import Collada DAE has been improved with support for texture and normal coordinates defined within the Vertices tag.

Enhanced:  Improved support for Forza Apex SwatchBin bitmap files.

Enhanced:  Rendering of shaders with cube maps improved.

Enhanced: DX10 BC5 and DX9 ATI2 formats are now decoded as normal maps.

Fixed:For AMD cards there is a fix to reduce the screen corruption which can happen when drag rotating a view with newer versions of the AMD drivers . To completely remove screen corruption switch to Software Mouse XYZ in the function Display-> DirectxX 9 Options.

Fixed: The Search path order defined by SCN files was reversed.

Fixed: Exporting to PNG could crash.

Fixed: Exporting to rF2 bone positions were incorrect if a pivot point was set.


3DSimED 3.1g Released

3DSimED 3.1g is released.

This is a maintenance release including a few enhancements.

FBX Export & Import now support  multiple UV texture coordinate channels.

The Edit->Object By Name function selects the previously selected Object.

Support has been added for DirectX 10 format DDS, and for Forza .Swatchbin .

There are fixes for GPL Import & Export and N2003 PTF Import.

Fixed: Texture coordinates for exported GPL models.

Fixed: Materials not set when importing GPL models.

Fixed: For a very few tracks, Nascar 2003 .PTF Importing and Updating could result in a corrupt PTF.
