Godot-Shader-Lib

Visual shader node library for Godot engine.

Adds various extra nodes to use in built-in visual shader editor.

Installation

Copy the contents of addons/ShaderLib into the same folder in your project. No activation needed. Custom visual shader nodes work the same way as standard visual shader nodes.

Uninstallation

Delete the contents of addons/ShaderLib folder from your project. Make sure to delete it using the Godot editor instead of your default file system program.

Nodes documentation

Procedural nodes

Noise

Voronoi node

Generates a Voronoi or Worley noise based on input UV. Voronoi noise is generated by calculating distances between a pixel and a lattice of points. By offsetting these points by a pseudo-random number, controlled by **_angle offset_**, a cluster of cells can be generated.

Inputs

Name	Type	Binding	Description
uv	vec2	UV	Input UV value
cell density	float	none	Density of generated cells
angle offset	float	none	Offset values for points

Outputs

Name	Type	Binding	Description
output	float	None	Output noise value
cells	float	None	Raw cell data

UV nodes

Flipbook 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.

Inputs

Name	Type	Binding	Description
uv	vec2	UV	Input UV value
rows	int	none	Amount of horizontal tiles in texture sheet
columns	int	none	Amount of vertical tiles in texture sheet
start frame	int	none	Start tile index texture sheet
end frame	int	none	End tile index texture sheet
anim speed	float	none	Animation speed

Outputs

Name	Type	Binding	Description
uv	vec2	None	Output UV value

---

Radial Shear node

Applies a radial shear warping effect similar to a wave to the value of input UV.

Inputs

Name	Type	Binding	Description
uv	vec2	UV	Input UV value
center	vec2	none	Center reference point
strength	float	none	Strength of the effect
offset	vec2	none	Individual channel offsets

Outputs

Name	Type	Binding	Description
uv	vec2	None	Output UV value

---

Rotate node

Rotates value of input UV around a reference point defined by input **_center_** by the amount of input **_rotation_**.

Inputs

Name	Type	Binding	Description
uv	vec2	UV	Input UV value
center	vec2	none	Center reference point
rotation	float	none	Rotation amount in radians
use degrees	bool	none	Use degrees instead of radians for rotation amount

Outputs

Name	Type	Binding	Description
uv	vec2	None	Output UV value

---

Spherize node

Applies a spherical warping effect similar to a fisheye camera lens to the value of input UV.

Inputs

Name	Type	Binding	Description
uv	vec2	UV	Input UV value
center	vec2	none	Center reference point
strength	float	none	Strength of the effect
offset	vec2	none	Individual channel offsets

Outputs

Name	Type	Binding	Description
uv	vec2	None	Output UV value

---

Tiling and Offset node

Tiles and offsets the value of input UV by the inputs **_tiling_** and **_offset_** respectively. This is commonly used for detail maps and scrolling textures over TIME.

Inputs

Name	Type	Binding	Description
uv	vec2	UV	Input UV value
tiling	vec2	none	Amount of tiling to apply per channel
offset	vec2	none	Amount of offset to apply per channel

Outputs

Name	Type	Binding	Description
uv	vec2	None	Output UV value

---

Twirl node

Applies a twirl warping effect similar to a black hole to the value of input UV.

Inputs

Name	Type	Binding	Description
uv	vec2	UV	Input UV value
center	vec2	none	Center reference point
strength	float	none	Strength of the effect
offset	vec2	none	Individual channel offsets

Outputs

Name	Type	Binding	Description
uv	vec2	None	Output UV value
