To Reply to US Navys post yes. But I will do it step by step
1) First go to Open BRF and go into the file in your Resource folder called ANI_Attacks. Then you should see (attacks_single_overswing, attacks_thrust_onehanded)
They have (old) at the end get rid of old by right clicking then renaming, delete the old part. and delete the names that don't have old at the end and are showing the animation of the new up attack and down u don't want.
Then save the BRF File.
2) Now go into your NW folder and find a file called actions. But for this you need you need a vanilla actions file. Which I have uploaded here:
https://www.dropbox.com/s/t32539gec2wjcts/Actions.rarDo not drag and drop it to your NW folder though open it then hit Crtl+f then type this in the search box which Is ctrl+f : ready_overswing_onehanded
Then you should see this: ready_overswing_onehanded 524800 1679839242 1
0.350000 attacks_single_overswing 5 16 7 0 0.0 0.0 0.0 0.0
Copy that then go to your NW folder with the actions and find that again but paste what you copied over it
Then save and your good.
