This custom block creates a field composed of 0s and 1s. If the translation location = 0, the field will equal 1 at all positive values of the field and 0 for negative values of the field. To reverse this, check the Flip input. This can be

***

This custom block creates a field composed of 0s and 1s. If the translation location = 0, the field will equal 1 at all positive values of the field and 0 for negative values of the field. To reverse this, check the Flip input. This can be useful when adding ramps or only applying a ramp to a certain section by multiplying this field with another.
