== Overview ==
The Vortex Warp shader uses a built-in vortex function to warp (distort) the texture coordinates used by the shaders attached to its Main Input. For example, this shader can be used to warp clouds, terrains and colour shaders.

'''Settings:'''

*'''Name:''' This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Vortex Warp shader nodes in a project.

*'''Enable:''' When checked, the node is active and the Vortex Warp shader will be applied to the surface or cloud layers. When unchecked, the node is ignored.

*'''Centre:''' This setting positions the centre of the vortex effect. These world space coordinates are in metres.
<ul>
[[File:VortexWarp_09_Centre.jpg|none|800px|The Centre setting determines the location of the vortex center.]]
</ul>

*'''Radius: ''' This setting controls the size of the area that is affected by the vortex effect the greatest. Higher values expand the vortex effect into surrounding areas. Smaller values centralize the vortex effect around the Centre coordinates.
<ul>
[[File:VortexWarp_10_Radius.jpg|None|800px|Increasing the Radius setting causes a larger area to be influenced by the vortex effect.]]
</ul>

*'''Vorticity:''' This setting controls the intensity of the vortex effect. Higher values draw the features closer towards the center of the vortex effect.
<ul>
[[File:VortexWarp_11_Vorticity.jpg|None|800px|Increasing the Vorticity value increases the vortex effect.]]
</ul>

*'''Reverse direction:''' When checked, the vortex effect is reversed, that is, it changes from spinning in a counter-clockwise direction to clockwise.
<ul>
[[File:VortexWarp_12_Reversed.jpg|none|800px|When the Reverse Direction checkbox is enabled, the vortex effect spins clockwise.]]
</ul>

*'''X axis:''' When checked the built-in vortex function is projected along the X axis.
<ul>

</ul>

*'''Y axis:''' When checked, the built-in vortex function is projected along the Y axis. This is the default behaviour.
<ul>

</ul>

*'''Z axis:''' When checked, the built-in vortex function is projected along the Z axis.
