Curve sampler

The curve sampler allows you to sample a custom curve of 1, 2, 3, or 4 dimensions:

Curve sampler

Curves contain values in a [0;1] range (see curve editor), and can be sampled with a cursor in that range. Sampling the curve a cursor at 0.5 will return the value at that position.

Editing a 2D curve


Curve samplers are most commonly used with the following templates:

  • CurverOverTime
  • CurveSample


Some effects might still reference the “Legacy_Field” template, but we recommend not to use it anymore, as it won’t be maintained.

Note: To edit color curves, we plan to have an improved color editor in PopcornFX v2.2 instead of the default curve editor.
