One of the last of my 1.5/XL ST uniforms ports.
It actually works much better the the XL version! With the basic trigger of "toddunf,star trek uniform,black jumpsuit,white shoulders" you should get the correct uniform almost every time (of course depending on the model also)
For me it worked fine with the wieght of 1.
It might help to add "headless" in the negative.
