A lightning-fast random number generator suite for Unity. Utilizing Burst/Job, Compute Shaders, and Rust, it empowers massive batch generation and simulations.Unlock unprecedented random generation speeds for your Unity projects. Ultimate RNG is designed from the ground up to solve the bottleneck of massive batch generations. By utilizing three powerful backends—Unity's C# Job System (Burst Compiler), Compute Shaders for GPU offloading, and highly optimized Rust native plugins—you can generate millions of random numbers in a fraction of a millisecond.This package provides a wide array of state-of-the-art RNG algorithms, including Xoshiro256, Philox, Mersenne Twister (MT19937, SFMT), SFC64, and more, allowing you to choose the exact balance between blinding speed and cryptographic-like quality.Perfect for:Procedural Terrain & World GenerationComplex Particle Systems and VFXLarge-scale simulations (flocking, traffic, fluid dynamics)Machine Learning and Monte Carlo simulations within UnityAny Data-Oriented (DOTS) workflow demanding heavy random samplingNote: Ultimate RNG is strictly specialized for batch generation and is not intended as a drop-in replacement for simple UnityEngine.Random calls in everyday, single-threaded Update logic.This asset requires a CPU with AVX2 support for maximum performance.Key Features:Blazing Fast Performance: Achieve up to 111x faster generation speeds compared to standard Unity or C# generators on bulk workloads.Multiple Backends:Job System / Burst Compiler: Native C# high-speed generation (Xoshiro256**, Xoshiro256++, SplitMix).Compute Shader: Direct-to-GPU generation (Philox32) for zero CPU overhead.Rust Native Plugins: The absolute gold standard in statistical quality and performance (MT19937, SFMT, SFC64, PCG32, etc.). The internal state of these Rust implementations is securely initialized from the seed using the SplitMix32/64 algorithm.Data-Oriented Design: Built natively for use with NativeArray, Span, and the Unity Job System.Unified Interface: Clean, consistent API whether generating from Jobs, Compute Shaders, or Native Plugins.Extensive Benchmarks: Comes with an integrated Demo scene to benchmark the performance in your own specific environment.Included Algorithms:Xoshiro256++ / Xoshiro256**Philox32 / Philox64Mersenne Twister (Mt19937 / Mt19937-64 / Sfmt19937 / Sfmt19937-64)Sfc64SplitMix32 / SplitMix64Pcg32Xorshift variantsI used AI to fix code, debug it, and create documentation.
