Curve sampler

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

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.

Curve samplers are most commonly used with the following templates:

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