Why is this so?

Because you have to change all the gamma on all the black and white maps to 1.00 on the node. Otherwise, you'll get thin results when using GC. Color maps are always 2.20. Black and whites, 1.00. SceneFixer (by Snarlygribbly) fixes all the maps to the correct gamma in one go.

Okay, I'm trying that now. I've used Snarly's script in the past, but haven't noticed that much of a difference.

Check all the top options.

When I run the script, I usually select the box that says, "All of the above," and run it on the entire scene. I'm trying it again right now to see what happens.

All Black and White maps that drive a node, like transparancy, bump & displacement have to load their B&W textures at Gamma 1.000

All color maps have to load with the default = Use render Gamma Correction.(2.2)

=> Check how the transmap for the lashes is loaded in the advanced materials tab.

Okay, Snarly's script didn't change the value for the eyelash transmap. I've now changed it manually and I'm running another render to see what happens.

I would check the advanced Material Room for anything different in the node arrangement.  Nodes directly plugged into the PoserSurface should change when applying Snarly's script.  If the transmap is nested within a node cluster, plugged into a value, or being shared as an image map, the script might not recognize it.

SceneFixer will recognise transmaps in a node cluster or plugged into a value.

However, if the transmap is also plugged into diffuse (i.e. being used as a diffuse imagemap as well) then it will be treated as colour rather than data. Of course, shaders should not be built this way :-)

I use the included ChangeGamma script under MaterialMods.  Enter 1.0, and select 'All Props and Figures' and 'All of the Above'...

Okay, so into what node SHOULD the transmapped eyelash texture be plugged?

It's better, is it not?

Black and white data maps should not be hooked into the Diffuse channel except in special circumstances (like driving a Blender node, for example). If you've got the transmap plugged into diffuse, specular, and transparency, it will probably read as a diffuse map and not be corrected by the script.

Transparency ;)

:)

looks ok to me. You could try different values between .45 and 1.
