on 1.13.2 version, I have a template that no matter how i testruin it, it is facing the same direction.. I tried to change the setting and it didnt work

testruin does not rotate templates by itself randomly. If you want to test rotation, you need to put it in the call parameters...

/testruin template x y z rotation
example:
/testruin templateparser/test 20 _ 40 1

_ for y means it will auto-adjust height to terrain, and rotation 1 is EAST, eg one quarter rotation clockwise.

thanks it works
