Integrating TressFX 5.0 into your Unreal Engine project
Now that we’ve taken a look at all the updates to TressFX 5.0, the important question is: how do you use it in your project?
PLEASE NOTE: In order to access this Unreal Engine patch, or any of our patches, you must be a registered Unreal Engine developer with access to the Unreal Engine GitHub repository.
If you haven’t changed the UE 5 engine files or shaders in your project then the integration process is really simple. You can directly integrate the patch file using a single command. The patch file is: UE544_TressFX_Engine_Patch.patch
Simply run the command below to integrate:
git am < UE544_TressFX_Engine_Patch.patch
If you have already made changes to the UE 5 engine files that TressFX is going to replace the previous approach will not work. Instead, you will need to manually copy the code segments surrounded by AMD TressFX BEGIN/END into the corresponding C++ files and shaders of your project.
Integration
- Apply the patch UE544_TressFX_Engine_Patch.patch to Engine.
- Copy Engine/Plugins/AMD/TressFX to your Plugins folder.
- Double Click GenerateProjectFiles.bat.
- Recompile UE5.sln.
- Autodesk® Maya® 2018 source asset is in Asset/Maya.
- A female avatar and a reasonable collision mesh which is used to generated correct SDF.
