Hey guys, I was actually able to port a few models from Ghosts.
I actually went to the extent of animating the gun using exported tanims from Lemon.
When I try to ADS down the gun, it does not go all the way.
I did export all the frames of the animation, and it looked fine in Maya.

Idle:


ADS:

Use a BO1 in foward games viewhands, the WAW viewhands doesnt have tag_ads

If you are using other hands with tag_ads and doesnt work, try to make a new ads up/down animation in Maya

i have this video but is in spanish, so watch the process xdd (2 ways, editing tag_ads or editing tag_torso)
