This addon is designed to create open worlds and eliminate the ugly "world break" effect. It generates a procedural horizon to surround your play area, making your world feel infinite without the performance cost of generating actual geometry for distant terrain.
It uses a Raymarching Shader applied to a flipped box mesh (similar to a skybox) to render mountains efficiently.
- Procedural Generation: Uses noise textures to generate infinite variations.
- Highly Optimized: Renders on a single mesh (12 tris) using shader magic. Runs at a stable 60 fps on old videocard AMD Radeon HD 8600/8700M (Integrated)
- Seamless Blending: Built-in fog gradient support to blend the mountains into your sky.
- Customizable: Full control over colors, scale, and fog depth.
- Download the repository.
- Copy the
addons/raymarched_mountainsfolder into your project'saddons/directory. - Enable the plugin in Project > Project Settings > Plugins (if applicable), or simply instantiate the node.
This addon is designed for ease of use.
- Add the RaymarchedMountains node to your scene.
- The node will automatically generate a box mesh around the center.
- Adjust the parameters in the Inspector to fit your art style.
- Heightmap: The noise texture used to generate the mountains.
- Tip: Use a
NoiseTexture2Dwith "Seamless" enabled for the best results.
- Tip: Use a
- FogGradient: A
GradientTexture1D. Use the alpha channel to control how the terrain fades into the sky at a distance.
- UV Scale: Controls the frequency of the noise (how "busy" the mountains look). Lower values = larger features.
- Terrain Scale: Controls the vertical height intensity of the mountains.
- Fog Start: The distance from the center where the fog begins to obscure the mountains.
- Fog End: The distance where the mountains become completely invisible (fully blended with the sky).
- Terrain Color: The base color of the mountain peaks/lit areas.
- Shadow Color: The color of the crevices and shadowed areas.
- Mesh Size: The size of the bounding box. Increase this if you need the mountains to be further away from the player.
