I tried working on makehuman again, I had used it before, but i uninstalled because I didn't use it.
I re-installed the latest version (from the official links) and tried changing the default skin texture, and i find this problem:
the textures seem to be not working, I checked the folders, and the files are there, but it doesn't work.
the clothes' textures are also not showing.
I already re-downloaded and it still doesn't work
