Animation Modifier 

The Animation modifier is designed to record and playback the cached version of your hair animation in real-time. You can export the animation of the guides or hairs to an .abc file using our Alembic Exporter and the resulting file will be automatically loaded into the Animation operator.

 

Parameters 

  • Strand Group
    This parameter works the same as in other operators, you can isolate the effect of the Animation to a particular Strand Group created in the Edit Guides modifier
  • Apply Amount
    Determines the intensity of the effect, can be used to blend animation.
  • File Path
    This is where you can load .abc file exported using the Alembic Exporter. This parameter also allows you to specify a new .abc file to save when using the Record functionality. There are two buttons next to the file path text box. One allows opening of an existing Alembic file, and another is to save new Alembic files if you plan to record current hair state or animation.
  • Time Offset and Time Scale
    You can use those two parameters to control the delay and playback speed of the animation.
 

Recording 

The recording section in the Attribute Editor allows you to capture one or more frames of static or animated hair and save them to an external _ Alembic.abc_ file. This state will then be used with this operator or with any other Animation Cache node which references the same .abc file.

The recording process will capture hair positions, widths, UV coordinates, strand groups, and any strand data. Current animation play range will be recorded. Therefore, before recording make sure you change the animation range to match your desired recorded results.

To begin recording press the Record Active Time Range button. During recording you can press the same button again to stop the recording process at any time. Any data already recorded will be saved.

Once the recording is done the Record Active Time Range button will change to display Clear Recorded Data. Pressing this button will delete any in-memory recorded data making the operator not do any changes to the hair.
