A low poly mesh terrain editor for stylized games that don’t use Unity Terrain, with paint and stamp tools, dense vegetation rendering, and performance focused terrain geometry.
Polaris Highland – Low Poly Terrain Tool v3.3.9
“Sharing is caring”
Description
Craft low poly terrain with adaptive geometry and optimized vegetation rendering for seamless realtime performance.
OVERVIEW
This is a low poly mesh terrain editor designed for stylized games that do not use Unity Terrain; it generates and renders terrain as regular meshes with a faceted low poly look.
The workflow is heightmap driven for speed and familiarity, while the final result is fully mesh based for stable performance.
It is built for developers who want full control over terrain shape and style, with a workflow optimized for stylized, mesh based environments.
CORE WORKFLOW
Terrain creation follows a simple, multi-tile paint and stamp workflow:
Create multi-tile terrain grids using the setup wizard.
Shape terrain geometry and textures with stamps and splines.
Paint colors, textures, and fine tune geometry with brushes.
Populate terrain with trees, grass, and props, and manage multiple terrains easily.
Procedural and manual editing work together, letting you block out large areas quickly and refine details by hand.
WHY MESH BASED TERRAIN
This tool generates fully mesh based low poly terrain, giving you:
Stylized visuals with flexible shading options, from faceted low poly to smooth or hybrid styles.
Stable performance across platforms, from mobile to desktop and VR.
Seamless integration with standard mesh workflows and rendering pipelines.
Ideal for low poly, stylized, and performance sensitive projects, it gives you control over both look and runtime behavior.
PERFORMANCE FOCUSED BY DESIGN
The system is designed to scale efficiently for realtime applications:
Generate terrain geometry with dynamic mesh density, keeping detail where needed while reducing overhead elsewhere.
Render dense vegetation and terrain efficiently, with integrated level of detail and culling systems.
Deliver stable performance across platforms, including desktop, mobile, and VR, under typical workloads.
SAMPLE CONTENTS
It comes with many sample assets for you to use in your project. These assets are used under permission of their creators.
Premade low poly terrain, trees, grass textures and rocks from Pinwheel Studio.
Environment structures and vehicles from Total Game Assets.
Trees from Distant Lands.
And more to come.
EDITIONS
This asset has 3 editions with different feature sets, from high to low:
Summit
Highland (this)
Valley
See comparisons.
You can upgrade from low to high edition at a reasonable fee, no “re-purchase” required.

THE ECOSYSTEM OF TERRAIN TOOLS & SHADERS
The terrain editor can be used on its own or alongside other tools and shaders from the same ecosystem. These are optional and not required for core functionality.
Polaris: Low poly terrain creation toolset.
Poseidon: Low poly water shader, stylized visual, optimal performance.
Jupiter: Stylized animated sky shader and day night cycle.
Vista: Graph based generator to create both low poly terrain & Unity terrain.
Texture Graph: Graph based texture generator to create seamless colored textures.
Contour: Fullscreen edge detection & outline effect.
Beam: Volumetric lighting & fog with local fog volumes.
===============================
NOTE
Some assets in the screenshots such as water and sky are NOT included in this package.
