Hi there, what Blender version are you using on your computer? Sims 4 Studio only supports versions 2.70 and 2.76, so any version higher than this will not work. That's the only reason I can think of as to why it isn't working for you. You might want to uninstall blender and search for 2.70 or 2.76 to install. Also, what happens when you try to select the pose you made? Does the character make a T-pose, or do they stand in an idle animation, etc?
