Continue by adding more stubs to the ground or any branches (hand drawn or procedural). You can draw part of the stub, rotate the camera, and continue drawing it to change the direction of the branch. | Continue by adding more stubs to the ground or any branches (hand drawn or procedural).

- | === Curve Fit === | + | === Curve fit === |
"Curve fit" is a scalar for the number of control points used to create the spline. A value of 1 results in an accurate spline that may have many control points based on the speed of drawing and other factors. Values less than 0.5 become inaccurate but have control points that are easier to work with (since each branch is composed of only a few control points). If using a low curve fit value, set the control point style to " | "Curve fit" is a scalar for the number of control points used to create the spline.
