Atlas Studio vs Heightmap Level Generator

Atlas Studio is a free, open-source Roblox Studio plugin for procedural 3D terrain generation through a visual node graph. Its documented library contains 56 nodes for generators, shaping, erosion, materials, and output. The workspace previews height, material, and slope, with an optional 3D mesh view. Paint Mask nodes provide a dockable canvas for local edits. Built-in recipes include Temperate Forest, Rolling Grassland, Rocky Highlands, and Island / Coast. Projects save the graph, bounds, seed, preview resolution, masks, environment settings, and build history with the Roblox place, allowing reuse. Final builds write native terrain in chunks on Roblox’s 4-stud voxel grid and fill empty voxels below the water plane with water. Preview resolution affects interactive previews only. Installation comes from the Roblox Creator Store and opens under Plugins → Atlas → Atlas Studio. Roads, structures, landmarks, models, and vegetation are outside scope, and materials use Roblox’s built-in terrain materials rather than custom textures.

Heightmap Level Generator creates procedural terrain and heightmaps in a browser for Unreal Engine, Unity and Godot. Its GPU-based generation uses WebGPU compute shaders and WGSL. Outputs include 16-bit heightmaps with features such as cliffs, hills, mountains, erosion, rivers, lakes and a raised border ring. It can also generate connected roads, towns, map exits, road grades and embankments around water, with temperate, steppe, desert and snow world biomes. Users can adjust settings live, compare 12 seeds, preview a 2D map and 3D mesh, and walk through terrain in first person. Exports include engine-specific terrain formats, Web or three.js formats, heightmaps, splatmaps, masks, water levels, color maps, layout JSON, glTF meshes and metadata JSON. Road, town and water masks and layout data can support PCG, Houdini and custom placement scripts. The free project supports share links, presets, JSON save and load, and undo and redo. Online use requires a WebGPU-capable browser; local use requires Node.js and such a browser.
