Quote - > Quote - PP2010 comes with such a script.

Go to menu Scripts / MaterialMods / changeGamma.

Enter 1.
Then select "all props and figures".
Then select "bump".

All bump maps are now gamma=1.

Then do it again for transparency maps.

Or choose the "all of the above" option. Then disp, trans, grad bump, and bump are all set to 1.

Semidieu's script is a lot nicer and graphically richer but this will do the job.

Cool, that sounds great

Works like a champ. The one problem, and it is a problem with Poser, not the script, is that if the same texture is used as both diffuse input and input into something else. Even if it is included in two different nodes, as long as it is the same file, Poser uses the gamma on it.
