Vec3 Math node
The Vec3 Math node performs various vector math operations between its inputs.

Inputs
The Vec3 Math node accepts two color inputs. Those inputs are optional, and when left unconnected, the corresponding parameter value is used
Outputs
The Vec3 Math node generates a single color texture that contains the result of the vector math operation.
Parameters
The Vec3 Math node accepts the following parameters:
the operation to be performed
default values to be used in place of the inputs when left unconnected
a boolean that specifies if the result must be clamped between 0 and 1
