I can’t seem to get yabee 7 or 10 to install in Blender 2.58. If I place it in my addons folder and use ctrl-alt-u it doesn’t show up in the list. If I manually install it I get no error warnings but it doesn’t appear in my export dialog.
I would just go back to Blender 2.4x and use chicken but it’s too deprecated for my current project. Also, using the X format and converting through Panda works but the file size and computational expense makes that method impractical when dealing with complex models.
