Creation method#

There are two options for creating a Blend Curve node.#

  • The first way to create a Blend Curve node is using the search list, which is opened by double left-clicking in the workspace. You can write the name of the node you need or words associated with this node.
    • blend , bc
  • The second way is to select a Blend Curve node from the menu that opens from the top left.
    • Menu > Tool > Primitive curves > Blend Curve

Steps#

  • Create a Blend Curve node.
  • Connect the first curve for blend to the first port.
  • Connect the second curve for blend to the second port.
  • Connect the bulge factor at A to the third port.
  • Connect the bulge factor at B to the fourth port.

After creating the node, you'll need to connect two curves to the "A" and "B" inputs, and then set the bulge factors for "FA" and "FB". Upon completion, you will receive the resulting curve through the output port.
