I'm working on creating tree trunks similar to the one in the image. The trunk is made using a Quadratic Bezier Curve and has a noise texture applied to introduce subtle randomness along its entire height. For the base of the trunk, I need an additional noise texture (or a different method) to create a semi-circular curved trunk part, but only in that specific area. I even made a sketch of how I would prefer the curve to look. You can check my nodes to see how I achieved that effect, but I'm looking for suggestions on how to achieve it with more control over the second noise texture. Thanks
