Access: Nodes > Math > Power
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 Examples
| Input (RGBA) | Calculation | Output (RGBA) |
|
Input A = 1.0, 0.213, 0.063, 1.0 Input B = 1.0, 0.454, 0.454, 1.0 |
R = 1.01.0 G = 0.2130.454 B = 0.0630.454 A = 1.01.0 |
1.0, 0.495, 0.285, 1.0 |
|
Input A = 0.5, 0.9, 0.1, 1.0 Input B = 0.1, 0.1, 0.1, 1.0 |
R = 0.50.1 G = 0.90.1 B = 0.10.1 A = 1.01.0 |

|
| 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. |
