Cartoon Procedural City Builder | Road Details | 01

In this episode, we begin creating procedural lane markings for the roads using Geometry Nodes. The setup includes three types of lines: outside shoulder lines, inside shoulder lines, and central lane dividers. To manage these, we first duplicate the necessary road curves and convert them into a reusable node group named lane_markings. We define dynamic controls for the number of lanes, lane width, shoulder width, and sidewalk width, all passed into the group as inputs. The outside and inside curves are offset using the shoulder width, then filleted to match the rest of the road geometry. Next, we use the Duplicate Elements node to generate multiple internal lane lines. Each copy is offset by an amount based on its index and the lane width, ensuring evenly spaced divisions. The logic supports any number of lanes and updates automatically. At the end, we prepare these generated curves for use in the next lesson, where we’ll convert them into actual dashed or solid lane markings. 🏙️ Key Moments & Timestamps 00:00 – Introduction Beginning the process of turning procedural lane curves into visible geometry. 00:22 – Creating the Lane Markings Node Group Wrapping the logic into a clean, reusable Geometry Nodes group. 00:58 – Converting Curves to Mesh Using Curve to Mesh with a custom profile to create lane lines. 01:39 – Building the Profile Shape Defining a narrow Curve Line as the cross-section for the markings. 02:21 – Orienting and Scaling the Profile Adjusting alignment and size of the markings along the road. 03:05 – Generating Dashed Lines Creating a dashed pattern using Sample Spline and index operations. 04:06 – Dash Length & Gap Controls Exposing parameters to control dash spacing and segment length. 05:18 – Applying Material Masks Generating attribute masks for shader/material control. 06:10 – Joining Markings with Road Geometry Merging the lane markings into the full road system. 06:58 – Node Group Organization Cleaning up the internal structure, labeling inputs and outputs. 08:20 – Testing Dash Variations Demonstrating how dash size and spacing adjust dynamically. 09:08 – Final Overview Reviewing the full setup and preparing for the next lesson.
