Are you using Wings 2.1 in the example you are showing?

Yes, but it also working in 1.5.4. It doesn't uses and newest GLSL stuff, so it's compatible with old versions of Wings3D.

What do the options Invert X, Invert Y, Colored Background, and Scale do?

They are parameters I saw/used in Gimp's Nomalmap plugin. The Invert X and Invert Y are used to change the way the map digs the surface, like this:


The Scale should affect the "height" data in the map changing the surface looks:


The Colored Background must be used when we are not using a gray scale image as input. In case checked it will be computed each pixel luminance, otherwise only the red channel is used.

Here is a short video showing how to use this filter:

p.s. It seems like the Invert Y must be checked to get the right effect. Someone else can confirm that?
