English version of yosa lab's opal material. The contents are the same as the Japanese version (日本語版: https://creator-tax-lab.booth.pm/items/9049419 ) — you only need one of them. An animated opal material for lilToon. The rainbow "play-of-color" drifts slowly across the surface and shifts with the viewing angle. Drag it onto clothes, accessories, hair, tails or props — most meshes work as-is (the pattern follows the mesh UVs). ■ Features ・Animated play-of-color: a slow, glowing flow inspired by opal's play-of-color ・Angle-dependent color: a rainbow MatCap plus glitter shifts the hue as you move ・Drag and drop: it is a lilToon material, so you just drop it on a mesh ・Easy to tweak: color, play-of-color strength, flow speed and pattern scale are all lilToon settings ・Light: textures are 1024 px or less (MatCap 512 px) ■ Colors Full version (¥500): White / Black / Pink / Blue / Fire / Lavender / Mint Opal (7) Free sample (¥0): White Opal only (1 color) — try it first to check the look on your avatar. ■ Requirements ・lilToon (free; available via the VRChat Creator Companion or lilToon's official page) ・Tested with Unity 2022.3.22f1, lilToon 2.4.1, VRChat SDK 3.10.5 ■ How to use 1.
