A small shader-lib package providing smooth (frame-blended) playback functions for sprite sheets (aka "particle textures").
ShaderGraph supported, sub-graph included.
Package is marked as compatible with Unity 2022.3.8f1 / URP 14.0.8 and up, but it probably works with MUCH lower versions. Though, it's not tested (try by yourself, but you'll need to edit versions in package.json).
Just clone it into your UnityProject/Packages folder, as com.darlog.frame-blending subfolder.
