Outputs the sum of the two input values A and B. Addition between vector data types are done per-component.
If A and B have a different number of components, a cast is performed to match the one with the greater number of components.
Addition operation is commutative so the order of values is not important.
The Add node takes color values from the first Sample Texture node and adds to them the values from the second Sample Texture node providing Albedo values for the Material. This node can be used to implement Additive Blending Mode (or Linear Dodge), for example.
