I was board and felt like creating another replacement for the now lost Adeptus Modificatus forum on Relic news (Green_Scorpion already made one, but there's nothing wrong with having two)
I place the model into object editor and mess around with it, (I also use default values on some modifier variables which won't get assigned in-game to adjust the speed which some attack animations play at, an interesting technique I found recently which can be quite useful for experimenting)
I also briefly use corsix mod studio to set up an entity and a squad for testing the model.
The model broke slightly when exporting (it's elbow joints started acting weird) but it's fine for a quick test
