# Rotate node
Rotates value of input UV around a reference point defined by input <b><i>center</i></b> by the amount of input <b><i>rotation</i></b>.<br><br><i>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>
