Way back in Poser 7, 9, or 10, I manually created a pose file that would change the Specular nodes across V4, witohout any impact on the rest of the skin textures (diffuse, image mapes, etc.). However, under P11Pro, this seems to be broken, with it completely wiping out the diffuse and other settings, leaving the skin a uniform matte black.

For instance, the start of one such .pz2 file is:

version
    {
    number 4.01
    }
figure
    {
    material 2_SkinTorso
        {
        KsColor 0.8 0.8 0.8 1 
        NsExponent 200.0
        ksIgnoreTexture 1 
        }

...and continuing the "material" blocks for each texture group through to the end, to give the figure a wet look.

This seemed to work fine up through P10, but now seems to be broken. What utterly obvious thing am I missing? ;-) ('Cause I know it's probably obvious to people more skilled with working deep in the files....)

(Edit) I'm rendering in Firefly using Auto settings, with the slider dialed all the way up to "Final" and with raytracing on. However, the textures turn black in the preview, before I ever render.
