Road Generator

Procedural Road Generator with Procedural Road Textures

This Geometry Nodes setup allows for fine-grained control over road generation with numerous adjustable parameters: Road width, material assignment, crack density and depth, detailed damage modeling (scale, spread, depth, displacement), and customizable striping patterns (width, color, spacing). Achieve photorealistic or stylized results with ease. Download now.

Let's break down each panel from the provided screenshot of the Geometry Nodes road generator setup.

Panel 1: Road Basic

• Smoothness: This controles the Smoothness of spline
• Width: This is a straightforward parameter that sets the overall width of the road.
• Material: To link Shader
• Color 1: The primary color for the road surface.
• Color 2: A secondary color

Panel 2: Crack

• Crack Seed: This acts as a random seed value.
• Crack Scale: Controls the overall size of the cracks. A larger scale means more cracks but smaller.
• Crack Depth: Determines how deep the cracks appear in the road surface. A higher value creates more pronounced.
• Crack Display: % to display the cracks
• Crack Displacement: Controls how much the road surface is pushed up or down by the cracks.

Panel 3: Strip

• Middle Strip: A dropdown menu to choose the type of center line striping.
• Middle Strip Width: Sets the width of the center line.
• Middle Strip Color: Allows you to change the color of the center line.
• Side Strip Width: Sets the width of any side lines (shoulder markings).
• Side Strips Color: Sets the color of the side lines.
• Side Strips Spread: Controls the spacing between the side lines (if present).
• Bump Strenght Strip: This controls how much the stripes are raised or indented from the road surface.

Panel 4: Overall Noise

• Overall Noise Scale: Introduces random texture variations across the entire road surface, simulating minor imperfections.
• Overall Noise Bump: Controls the height of the small bumps and irregularities added by the overall noise.

Panel 5: Damage

• Damage Scale: Controls the overall size and number of damage areas (potholes, etc.).
• Damage Seed: Similar to "Crack Seed," this randomizes the placement of damage.
• Damage Spread: Determines how widely the damage is spread across the road.
• Damage Detail: affects the level of detail in the damage modeling, making it look more or less realistic.
• Damage Depth Cut: How deep the potholes or damage areas are cut into the road surface.
• Sediment Distribution: Controls how much sediment (dirt, gravel, etc.) accumulates in damaged areas.
• Damage Displacement: Similar to "Crack Displacement," this controls how much the road surface is deformed by the damage.
• Damage Bump: Controls how much the damaged areas are raised or lowered.\
