Description

Liquid Shader Breakdown (May 2019) is a Cyanilux URP Shader Graph post adapting Minions Art's liquid look. Free on cyanilux.com with no login, in the same breakdown series as other Unity shader articles.

It discards fragments above a height threshold using world Position minus Object position, Alpha Clip, and Two Sided back faces for the meniscus. Branch with Is Front Face tints liquid, top foam, and rim foam; sine wobble offsets height via Time and amplitude properties.

For intermediate users who know Shader Graph and clipping. Notes cover pivot at center of mass, Unlit versus lit back-face normals, and links to CrossSection UV ideas for textured tops.

Intro, Notes, and a screenshot Breakdown walk the graph step by step; glass shader is not included.

Handy for bottles and fill bars without rigged geometry. Cyanilux breakdowns are widely bookmarked in Unity shader communities.
