Creation method#

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

  • The first way to create a Tween 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.
    • crv , tc
  • The second way is to select a Tween Curve node from the menu that opens from the top left.
    • Menu > Tool > Primitive curves > Tween Curve

Steps#

  • Create a Tween Curve node.
  • Connect the first curve to the first port.
  • Connect the second curve to the second port.
  • Connect the tween factor to the third port.

After creating the node, you'll need to connect two curves to the "A" and "B" inputs, and then set the "F" input to a value between 0 and 1 to determine the point of interpolation. A value of 0 will output the curve connected to the "A" input, while a value of 1 will output the curve connected to the "B" input. A value of 0.5 will output a curve that is halfway between the two input curves.
