Procedural Low-Poly Mountain Shader

-> Web-Demo

Procedural Low-Poly Mountain Shader (URP)

Generate stylized mountains directly from flat ground planes – no 3D modeling required. This shader uses controlled vertex displacement to shape a mountain profile with fully adjustable parameters:

• Size (width, height, depth)
• Steepness (controls the angle of slopes)
• Complexity (number and scale of peaks)
• Roughness (height variation between peaks and valleys)

Advanced features:

• Color layering to simulate elevation or temperature zones
• Sun rotation for stylized lighting based on time-of-day
• Underground offset to avoid floating geometry on uneven terrain
• Invisible proxy mesh ensures rendering even if the source plane is off-screen

Two shading styles are included:

1. Organic Layering Shader: Smooth transitions between elevation-based colors
2. Face-Based Shader: Sharp transitions per polygon for a stronger low-poly look

A demo scene is included with live controls:

• Adaptable parameters from inspector
• Realtime sliders for all key parameters
• Randomize button with seed control
• WebGL-export ready, including responsive layout

This shader is optimized for background terrain and visual atmosphere. It is not a complete 3D-Object and does not support:

• Collision
• Physical geometry
• Real-time shadows (on itself or other objects)
• Backside (only visible from the front)

Perfect for low-poly scenes, stylized world backgrounds, procedural environments, and lightweight simulations.
