Build Worlds, Not Formulas Strata is a visual, node-based heightmap authoring tool designed for game developers and environment artists who want procedural power without writing a single line of code. Connect noise generators, filters, and masks in an intuitive node graph. Watch your terrain take shape in real-time — then export a production-ready heightmap in seconds. A Node Graph Built for Terrain Every element of your landscape is a node. Chain them together, tweak parameters with live sliders, and see the result update instantly in the 2D preview or the 3D mesh viewport. Nothing is destructive — change anything at any time without starting over. Noise Generators — Perlin, Simplex, Voronoi, and Gradient nodes with full parameter control Island Cluster — Place archipelagos and continental masses with scatter, elevation, and shape controls Domain Warping — The Warp node bends terrain organically using fractional Brownian motion, breaking up artificial-looking repetition Thermal Erosion — Simulate natural erosion and sediment flow to give your terrain geological believability Shoreline Mask — Automatically generate masks along coastlines for blending beach, shallow water, and land textures Full Math & Filter Library — Add, Subtract, Mix, Clamp, Power, Invert, Terrace, Smooth, Sharpen, Remap, and more Real-Time 2D and 3D Preview Switch between a high-resolution greyscale heightmap view and a lit 3D terrain mesh with a single click. Adjust vertical scale on the fly to evaluate your terrain at any exaggeration level. A moveable export box lets you frame exactly the region you want to export — no guesswork. Export Ready for Your Engine Strata is built around the formats and resolutions your engine actually needs. Unreal Engine 5 — Correct landscape resolutions (127, 253, 505, 1009, 2017, 4033, 8129) exported as 16-bit PNG or R16 raw Unity Terrain — Power-of-two-plus-one sizes from 33 to 4097, 16-bit PNG Godot — Power-of-two sizes from 64 to 4096 Generic PNG — Any standard resolution for custom pipelines Export a single tile or divide your world into a 2×2 or 4×4 tiled grid — each tile compiled separately with its own bounds, ready for large open-world workflows. Splat Maps Included Add a Splat Output node to your graph and Strata generates a four-channel RGBA texture alongside your heightmap — giving you an instant texture weight map for landscape material layers in any engine. Normal map export is also built in: one checkbox and Strata computes a tangent-space normal map from your heightmap at full export resolution. Save, Iterate, Come Back Your entire node graph saves to a compact .strata project file. Open it a week later, adjust a single parameter, and re-export in seconds. Full undo/redo history keeps experimentation risk-free. Who Is Strata For? Indie game developers who need production-quality terrain without a AAA art pipeline Environment artists prototyping landscape layouts before committing to manual sculpting Level designers who want to iterate on world shape quickly Procedural art enthusiasts who want to explore generative landscape forms Strata is in active development. Features and node types are added regularly based on community feedback.
