Spline Append | Substance 3D Designer

Node icon

In: Spline & Path Tools > Spline Tools

Description

Splines are packaged as a list. This node appends a list of input splines (set #2) onto an existing list (set #1).

The order of the lists is preserved, meaning appending a list D-E-F onto a list A-B-C results in a list A-B-C-D-E-F.

Tip:

Be mindful of the order in which you append splines, as this order is taken into account in other nodes, such as Scatter on Splines, the Spline Bridge nodes, etc.
