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.

A Color node with a value of 1.0, 0.213, 0.063 raised to the power of a Color node with a value of 1.0, 0.454, 0.454.

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.
