CLV2CRINKLY4

CLV2CRINKLY4 is a procedural texture engine and shader library used in computer graphics to generate crinkled surface patterns. The name combines CLV2, a cellular lattice vector algorithm, with CRINKLY, a texture module that adds controlled irregularities to simulate crumpled materials such as paper, foil, or wrinkled fabric. The system supports real-time rendering for game engines and offline rendering for film, delivering seamless textures through parameterized controls.

Technical concept and workflow: The engine uses a node-based workflow that blends lattice generation, tiling, and layered noise. CLV2 arranges samples in a repeating lattice that acts as a scaffold for crinkle displacement. The Crinkly module then applies height and normal perturbations with adjustable scale, contrast, and anisotropy. Output includes 2D textures (diffuse, roughness, normal, displacement) and shader code for major engines.

History and versions: Introduced in 2020 by VertexForge Labs, CLV2CRINKLY4 has progressed through four major revisions, with version 4 released in 2024. Releases added finer control, GPU acceleration, and improved tiling stability at high resolutions.

Applications and reception: It is used in film, architectural visualization, and games to create realistic crinkled surfaces with minimal texture painting. It is valued for consistent results across platforms, though heavy tiling at small scales can require careful parameter tuning.
