# Power Node

Access: NodesMathPower The Power node outputs the value of A raised to the power B. This can be useful to raise base color values to become darker or lighter, depending on the exponent.

For the inputs A = [R G B A] and B = [X Y Z W], the Power node performs the following calculation:

RX, GY, BZ, AW.

# Power Node Inputs

 A The value to raise to the power B. When no node is connected, the value defaults to the value specified in Default Input A. B The power to raise A to. When no node is connected, the value defaults to the value specified in Default Input B.

# Power Node Properties

 Default Input A text field, slider The value to use for A if no node is connected to the A input. Default Input B text field, slider The value to use for B if no node is connected to the B input. R checkbox If checked, the red component of A is raised to the red component of power B. If unchecked, the red component is passed through to the output as the original value of input A. G checkbox If checked, the green component of A is raised to the green component of power B. If unchecked, the green component is passed through to the output as the original value of input A. B checkbox If checked, the blue component of A is raised to the blue component of power B. If unchecked, the blue component is passed through to the output as the original value of input A. A checkbox If checked, the alpha component of A is raised to the alpha component of power B. If unchecked, the alpha component is passed through to the output as the original value of input A.
