There’s a reason modeling software focuses on curvy women – it all sucks. Without motion capture posing is damn near impossible. It’s so difficult that poses – just poses – for existing models are sold separately and by third parties.
And just to pour salt in the wound, these apps all have Mac versions (they’re usually written in python not a real language) but with second class support. “Mac Versions” of “older” (like 2 years ago) models come in .sit files, which decompress into a VISE (remember those?) PPC .app. Newer ones are zips but still an installer executable (not a bundle.app). The Windows versions are .zips of .exes. Why can’t they just be a single .zip with a few shell scripts?
