Notes on deploying Creature Animations in Unity

Please note you have the following options to deploy Creature animations in Unity:

  • Standard CreaturePlugin, all the features for main character gameplay requirements
  • CreaturePack, for character crowds, NPCs and scenarios where very high performance playback + loading is required
  • FBX, you can export a character as a FBX asset from Creature if it just uses Bone Motors ( Bone Skinning ), allowing you to use the full Unity Skeletal Animation pipeline

Deploying for iOS and other platforms

If you are having issues with deploying for platforms like iOS ( UnusedBytecodeStripper2.exe did not run properly etc. ), you should give the following a go:

  1. Remove the CreatureFlatData.dll from the Distro directory

  2. Create a new folder in your project and include the files:

Creature FlatBuffers Source

  1. Build and deploy your project

This should remove any sort of DLL dependency on your project.
