Your second post doesn't clarify the point, IN.

Robyn knows the multiplication setting is "within Lightwave".

Poser connections are multiplication, and Robyn wonders why you want to change the math when converting to a LW shader.

I suspect that a LW shader "layer" is a different thing and the blending mode has to do with how the layers are combined. However, I can't imagine how it would matter if you only have one layer. I also can't imagine how multiply could result in a "pale washed out appearance" unless there is another layer which is not white, but gray.

You can try this in Photoshop. Set up a background layer, all white. Add another layer with some image in it. Set the mode to multiply. No change.

Now go down to the white layer and make it gray. The second layer multiplied with the first (which is no longer numerically 1) will appear darker and less contrasty. Multiplication with 1 has no effect. Multiplication with less than 1 does.

If you multiply with black (numerically 0) the result is always black.

These are simple consequences of the rules for multiplication.

x * 1 = x

x * 0 = 0

x * k < x where 0 < k < 1
