The FBX file format is used by a lot of applications today including Blender, Modo, and many more. Since Project Anarchy doesn't directly support FBX format, this tool will take a FBX file and automatically convert it to a format that can be used with Project Anarchy. It will:
- Convert FBX files with animated objects to rig and animation files that can be used with Animation Studio
- Convert FBX files with static objects to Vision static mesh files (.vmesh)
For the most recent packaged version, go to the main Project Anarchy download page: http://www.projectanarchy.com/download
Here are the tools included in the package:
- Bin\Tools\FBXConverter.exe - This takes an FBX file as input, calls FBXImporter.exe to generate the HKX files, and then it takes the outputted files and generates corresponding Vision or Animation Studio compatible files by calling the Havok Content Tools standalone filter manager (hctStandAloneFilterManager.exe). If you just have source, then this won't exist until you run the packaging step (see Packaging section below), which converts the Tools\FBXImporter\Bin\Scripts\convert.py script into an executable.
- Bin\Tools\PreviewTool.exe - Drag/drop outputted hkx/hkt files onto this executable and it will attempt to find the Havok Content Tools preview tool (ToolStandAlone.exe) and use that to preview the asset. You can just as easily
- Tools\FBXImporter\Bin\FBXImporter.exe - Takes an FBX file as input and converts it to a Havok scene file (e.g. a tag file with extension .hkx or .hkt). Usually won't need to call this manually as FBXConverter.exe will call it.
Extract the package (e.g. ProjectAnarchy_FBXImporter_20130730.zip) to the root of your Anarchy SDK folder (e.g. C:\Projects\Havok\AnarchySDK). To convert an FBX, just drag/drop your FBX file onto the executable. There are also some command line options available, which you can read more about below. The process that FBXConverter.exe (i.e. the executable version of Tools\FBXImporter\Bin\Scripts\convert.py) does behind the scenes is:
- Call Tools\FBXImporter\Bin\FBXImporter.exe on the FBX which will generate an HKT (i.e. Havok Scene File) for each take / animation-stack in the FBX.
- Generates an HKO / filter-set for each HKT using one of the templates in Tools\FBXImporter\Scripts\configurations.
- Call hctStandAloneFilterManager.exe on each HKT and pass in the corresponding generated HKO file. For example, it might call it like this:
hctStandAloneFilterManager.exe -s StaticBox.hko StaticBox.hkt
- Bin\Tools\FBXConverter.exe [Options] model.fbx
Options:
- -h, --help: Show help message and exit
- -i, --interactive: Use interactive mode which will bring up the standalone filter manager
- -q, --quiet: Don't print out status updates
- -m, --model: Output a Vision Model file (does NOT include animations!)
- -s, --static-mesh: Forces it to output a static mesh and not a model with animation
If you have an FBX file named StaticBox.fbx that has no animations, passing it to convert.py will generate the following files:
StaticBox.vmeshStaticBox.hktStaticBox.hko- The configuration (filter set) that's passed to the filter tools.
Some packages, like Blender, will always export an animation stack which will make the converter think that it's an animation. To force it to output a static mesh, pass '-s' or '--static-mesh' as a parameter to the converter.
If you have an FBX file named AnimatedBox.fbx that has one animation named Bounce, passing this to convert.py will generate the following files:
AnimatedBox.hktAnimatedBox.hko- Used to generateAnimatedBox__out_rig.hkx.AnimatedBox__out_rig.hkx- Rig file used for Animation Studio. Put this in the CharacterAssets folder.AnimatedBox__out_anim_Bounce.hkx- Contains animation data that is compressed and includes extracted motion. Put this in the Animations folder.AnimatedBox_Bounce.hktAnimatedBox_Bounce.hko- Used to generateAnimatedBox__out_anim_Bounce.hkx.
These files are to be used with Animation Studio.
If you have an FBX file named StaticBox.fbx, passing it to convert.py along with the '-m' or '--model' command line parameter will generate the following files:
StaticBox.modelStaticBox.hktStaticBox.hko- The configuration (filter set) that's passed to the filter tools.
NOTE: Generated Vision model files do not yet support animations
- Visual C++ 2010
- Python 2.7.X
- FBX SDK 2013.3 VS 2010 - We will be upgrading to 2014.1 soon!
- Python Tools for Visual Studio - Useful for debugging your projects and we include a .pyproj/.sln so you'll need to have it installed to successfully open the solution.
- py2exe - Needed if you're going to create a package
- Install the Project Anarchy SDK from the homepage
- Make sure the Havok Content Tools (32bit or 64bit) and Havok Anarchy SDK are downloaded and installed
- Install FBX SDK 2013.3 VS 2010
- Git clone the repository into $(AnarchySDK)\Tools\FBXImporter. From $(AnarchySDK)\Tools on the command line execute the following:
git clone https://github.com/projectanarchy/fbximporter.git FBXImporter
- Open $(AnarchySDK)\Tools\FBXImporter\Workspace\FBXImporter.sln
- Build the project using Dev DLL Configuration. This will output an executable to: $(AnarchySDK)\Tools\FBXImporter\Bin\FBXImporter.exe
Although the steps for generating packages is simple, there are a lot of caveats with generating binaries with py2exe and sometimes executables generated from different versions of Windows behave differently.
- Install py2exe
- Run $(AnarchySDK)\Tools\FBXImporter\Package\package.bat
- If all went well, you should have a package in the $(AnarchySDK)\Tools\FBXImporter\Package\Output folder
