# Parallax mapping node
The Parallax Mapping node lets you create a parallax effect that displaces a Material's UVs to create the illusion of depth inside a Material.<br><br><i>This node is only available in shader modes SPATIAL and CANVAS ITEM.<br><br>Default value for uv input will be vec2(0, 0) for shader modes <i>PARTICLES</i>, <i>SKY</i> and <i>FOG</i> to avoid errors becouse UV variable is not available for these modes.</i>
