I actually use both. But, I tend to use -md5s first just because they load up quicker in 3d Object Converter. Habit I guess!
Yes, I did find more bind-pose models and med-res textures in .umap files inside the Kismet and Crowd folders.
But... Where's Mr. Flynn and Siren's High-Res textures?
I think I figured it out... The characters in ModelGallery also have a AnimSet folder that contains character turntable, infected and sentry poses to be loaded once the .psk file is opened up in 3dsmax.
But, like ESR911 mentioned. Actor X freezes 3dsmax when trying to change poses.
Makes sense. No? What do you think?
