Versions: v1.0 

File Size: 55 MB

Download SHC Large Scale Terrain Generator for Blender on Windows and Mac, a powerhouse addon designed to create, import, and manage massive, real-world scale terrains without crashing your viewport or blowing up your file size. Whether you are generating endless procedural wilderness, importing real-world GIS heightmaps, or building continent-scale environments for cinematic fly-throughs, this tool handles the extreme geometry and memory management required for massive landscapes. It bridges the gap between artistic procedural generation and geographic accuracy, allowing environment artists to build worlds that span hundreds of square kilometers while maintaining high frame rates.

Key Features of SHC Large Scale Terrain Generator:

• Infinite Scale & Virtual Management: Handle terrains spanning hundreds of square kilometers using smart LOD (Level of Detail) and chunking techniques. The addon automatically divides massive meshes into manageable tiles, ensuring your viewport remains responsive.
• Real-World GIS Import: One-click import of real-world elevation data (GeoTIFF, HGT, RAW) and satellite imagery. The tool automatically geo-references, scales, and aligns them to true 1:1 real-world dimensions, complete with coordinate system support.
• Procedural Macro & Micro Detail: Combine large-scale tectonic shapes with high-frequency procedural noise for rocks and soil. Ensure the terrain looks geologically accurate from a bird’s-eye view and holds up to ground-level macro photography.
• Automated Splat Mapping & Biomes: Project high-resolution texture splats (grass, rock, snow, dirt, sand) based on slope, height, curvature, and moisture levels. The system is optimized for massive draw distances without texture stretching.
• Smart River & Lake Carving: Procedurally carve riverbeds, canyons, and lakes into the terrain using spline tools. Automatically generates realistic water planes, shoreline erosion, and sediment deposits.
• Dynamic LOD & Culling System: Automatically generates lower-resolution meshes and impostor billboards for distant terrain chunks. The smart culling engine hides off-screen tiles, keeping viewport FPS incredibly high even with millions of polygons.
• Vegetation & Asset Scatter Integration: Seamlessly links with major scattering addons or utilizes a built-in optimized scatter engine for placing millions of trees, rocks, and grass blades using GPU instancing.
• Game Engine Tiling Export: Tools to split massive terrains into optimized, perfectly seamless tiled chunks (e.g., 1km x 1km tiles) with generated collision meshes, ready for Unreal Engine, Unity, or Godot.
• Non-Destructive Geometry Nodes Backend: Built entirely on Geometry Nodes, allowing you to tweak erosion, height, noise parameters, and tectonic shifts at any time without destroying the base data.
• Atmospheric & Fog Integration: Includes preset volumetric fog and atmospheric scattering setups that automatically scale with your terrain’s altitude, creating realistic cloud layers and horizon haze.

Perfect For:

• Environment Artists building open-world games, flight simulators, and massive cinematic landscapes.
• Architectural Visualizers & Urban Planners importing real-world topography for city-scale developments, infrastructure projects, and environmental impact studies.
• VFX Studios creating large-scale exterior plates, matte paintings, and digital doubles of real-world locations for film and television.
• GIS Professionals & Map Makers visualizing real-world elevation, geographic data, and topographical maps in immersive 3D.
• Game Developers needing optimized, tiled terrain exports and automated LODs for large-scale open-world engines.
• Concept Artists rapidly blocking out massive, continent-level environments for pre-production and world-building.

System Requirements:

• Blender: 3.6, 4.0, 4.1, 4.2, 4.3, 4.4+ (Geometry Nodes heavily utilized; optimized for Blender 4.x).
• OS: Windows 10/11 (64-bit) or macOS 10.15+.
• RAM: 16GB minimum (32GB to 64GB+ highly recommended for massive GIS imports, high-res splat mapping, and dense scattering).
• Render Engine: Fully compatible with Cycles (for accurate displacement and volumetrics) and Eevee.

Installation:

1. Download the SHC Large Scale Terrain Generator .zip file.
2. Open Blender and go to Edit > Preferences > Add-ons.
3. Click Install…, select the downloaded file, and enable the checkbox next to Add Mesh: SHC Terrain.
4. Access via the Add Menu > Mesh > SHC Terrain or the dedicated Terrain Manager panel in the 3D Viewport Sidebar (N-panel).

Key Highlights of the Latest Update:

• Blender 4.4 Compatibility: Full support for the latest Geometry Nodes simulation fields, massive point-cloud instancing updates, and AgX color management for stunning environmental visuals.
• Enhanced GIS Parser: Faster loading times and improved memory paging for multi-gigabyte GeoTIFF files, preventing Blender from freezing during large data imports.
• New “Tectonic” Presets: Added procedural presets for generating realistic mountain ranges, fault lines, continental shelves, and karst landscapes.
• Optimized Tiling Export: The game engine exporter now automatically generates seamless collision meshes, navigation meshes (NavMesh), and LODs for each terrain tile.
• UI Overhaul: A dedicated “Terrain Manager” panel to easily swap between different terrain chunks, manage their individual LOD settings, and control global splat map resolutions.
• Performance Boost: Rewritten the viewport evaluation cache, resulting in a 50% faster viewport response when panning across massive, multi-tile landscapes.

Note:

SHC Large Scale Terrain Generator is built on the philosophy that scale should never compromise quality or performance. Traditional terrain tools in Blender often choke when pushed beyond a few square kilometers, resulting in massive file sizes and unusable viewport lag. SHC solves this by treating the terrain as a managed, tiled ecosystem rather than a single, monolithic mesh. Whether you are importing the exact topography of the Swiss Alps for an ArchViz project or procedurally generating a fantasy continent for an RPG, SHC provides the robust, memory-efficient pipeline needed to bring massive worlds to life.

Originally developed in Blender 3.0 If you have issues with newer versions of Blender, i recommend using 3.0 or 3.6

This is not a plugin, it is a .Blend save file with a terrain shader, lighting, camera setup and atmosphere in it

Short description

This is a large scale procedural terrain generator with 3D nature and cities for Blender Cycles.

The terrain is made with procedural noise and the 3D structures and trees are generated by saved displacement images. This doesn’t need any mods or plugins to use.

This download contains a procedural terrain setup with atmosphere. everything is textured and features city lights for night time renders. This model can be used for commercial purposes and is originally developed for Blender Cycles only.

Instructional video

There is a text file included with a link to a short instructional YouTube video to give some guidance to using this project

Closeup water

Due to the scale and complexity of the setup, there can be some errors visible in the water when near it. There is a ‘’closeup water’’ object that might need slight height adjustment right above the original water to block these errors.

Seed Parameters

In the shader of the terrain there is a set of parameters where you can generate a seed of your liking

There is a general seed parameter that randomizes everything every time you change it.

There is also more parameters for more precise tweaking like: Mountain, desert and city location seeds.

There is also parameters to increase or decrease biomes. For example you can have a 100% snow or desert map, or 100% skyscrapers.

Camera setup

There is a second wide angle camera behind the main camera that’s responsible for the adaptive displacement. This camera will give priority to closer details compared to far details (for optimization reasons)

Performance (Cycles)

The scene is optimized to get as much details with as little memory usage as possible. I would still recommend a system with at least 8gb RAM (and 6gb GPU memory if you decide to render on your GPU).

If your GPU doesn’t have enough memory, you can always choose to render on your CPU.

I have included some example settings and how much memory usage there is in the images above.

All renders on this page are rendered with 32gb of ram.

·         Advanced users can replace the cities and forests by their own diffuse and heightmaps.

·         Advanced users can bake the setup for exports.

Other engines/software

This is developed for renders in Blender Cycles only.

But with intermediate experience in Blender, it is possible to bake the diffuse and greyscale of this terrain shader for export purposes. The quality will be lower than the native terrain setup in Blender since images only have a certain amount of greyscale levels (256 for jpeg and png)

Use cases

(commercial/monetized) Examples for this scene can be used for: Game / Environment design ideas, concept art, 3D backgrounds, VR, AR, Research, high altitude renders, Greenscreen, Animation, advertisement, Education, presentations, city design study, landscape study, NFT, Film scene, HDRI

Feel free to edit and modify as much as you like.

Textures

Textures are custom made. But the grass color, rock and sand are CC0 textures from Polyhaven.
