# Godot-Shader-Lib
Visual shader node library for Godot engine.
Adds various extra nodes to use in built-in visual shader editor.
## Installation

### UV nodes

#### Flipbook uv node
Creates a flipbook, or texture sheet animation, of the UVs supplied to input UV. The amount of tiles on the sheet are defined by the values of the inputs **_rows_** and **_columns_**.
This node can be used to create a texture animation functionality, commonly used for particle effects and sprites, by supplying Time to the input Tile and outputting to the UV input slot of a Texture Sampler.
