NoiseKit
Modular, Blueprint-friendly noise generation: combine value, gradient, simplex, cellular and white noise with select, blend, warp and shaping modules.
Highlights
All 9 features →NoiseKit generates coherent noise for terrain, scattering, textures and procedural layouts. Create a core generator with a single node (value, gradient, simplex, cellular or white noise, with FBM, Billow or Rigid Multi fractal layering), then sample it in 2D or 3D anywhere in your Blueprints or C++.
Generators are small modules you can chain: select between two or three inputs with smooth falloff, blend through a float curve, add with a mask, scale and bias, domain-warp, switch by radius, flatten shorelines or build a distance field from spline components. The last module in the chain is the one you sample.
Use it for heightmaps, biome masks, foliage density, cave and ore placement, river and road influence from splines, or any gameplay that needs smooth, repeatable pseudo-random values from a seed.
NoiseKit is part of the Alpha XP utilities collection for Unreal Engine 4.27 and 5.8. Every feature is exposed to Blueprints and C++, it ships with styled HTML documentation, and it is compiled and verified warning-free against clean UE 4.27 and UE 5.8 projects.
