You can build Bump and Specular maps easy from within Poser using Math_Functions nodes.

For Specular Maps => True White is max Specular, and true BLACK is NO Specular. For Bump Maps => True White is max Bump, and true BLACK is NO Bump.

In the example shown, you will see that the higher Math Node builds the specular map and that the area's like brows go dark = less specular on the brows as it should be.

And the lower Math Node converts the brow area to a more white color. => Brows need bump, thus all light area's get more bump.

The above setup is my default to let Poser automatically create Specular and Bump maps from Diffuse textures. No external apps needed, only one texture to worry about, and easy on the memory too.

And what is more? ? All internal Poser render engines get the same results. ( Preview, FireFly, FireFly Progressive, SuperFly. )

Just remember the basic rules. White = More specular and more Bump. Black = Less specular and less Bump.

Like the brow example? Brows (or public hairs) need less specular but more bump. => That is where the 2 Math function nodes are for.
