Ive noticed, when switching the inputs of the combiner (i.e. top to bottom, bottom to top) the output is different, even with the blend at 50%.
Is this deliberate?
It depends on the combining method you use…
For instance, for the Average method, the strength needs to be set to 0.5 in order to get the real average between the two inputs.
But for the Multiply method, it has to be set to 1.0…
