Animation track attribute samplers

UE AnimTrackSampler

Available properties

The plugin allows you to modify the following properties of your anim track sampler:

UE AnimTrackProperties

  • Target actor: The target actor that contains a spline component to sample

  • Spline component name: The spline component name in the target actor

  • Translate: Enable translations

  • Rotate: Enable rotations
    Please note: If you need accurate orientations, disable "FastSampler".

  • Scale: Enable scale

  • Fast sampler: Enable this to use PopcornFX curve sampling for better performance. The drawback is a lack of accuracy when sampling orientations.
    If you stick to positions or scale sampling keep this option enabled.
    Disable this option if you need accurate sampling for orientations, keep in mind this will be less efficient.
    Don’t hesitate to contact support for more informations.
    Note: Restart emitters referencing this sampler when this value gets changed

  • Editor rebuild each frame: EDITOR ONLY: Enable this to rebuild the curve every frame. Useful to iterate quickly when building a spline component

  • Transforms: Determines what transforms will be used for this attribute sampler:

    • Spline Component Relative Tr: Use Spline Component local transforms relative to it’s parent actor

    • Spline Component World Tr: Use Skinned Component world transforms

    • Attr Sampler Relative Tr: Use Attribute Sampler component local transforms relative to its parent actor

    • Attr Sampler World Tr: Use Attribute Sampler component world transforms
