Okay, I understand now! For those seeking assistance I\m gonna share my knowledge as best I can 1: Import _humanoid.gla with animations and specify start frame and animation range (These numbers can be found with modviewer) 2: insert a T-pose at frame -1 by selecting all bones and clearing pose transforms 3: modify animation 4: export GLA (I exported from frame 0 to the end of the animation, basically excluding the t-pose but I put it in there just for good pratice) 5: place GLA in the same folder as GLAmerge and the original _humanoid.gla (or whatever GLA you wanna add your animation onto) Here is the trick, GLAmerge actually add your animation last in the GLA, it doesnt override the original one so you have to change the animation.cfg to make the modified animation target a different set of keyframes in the GLA. basically, just take the start frame from the last animation in the list + the length of said animation and place it on your modified animations start frame. Next you can rename your new merged GLA file _humanoid.gla and place it in a PK3 together with the modified animations.cfg and enjoy your new animations And thanks for the help ramikad! Also, a good tip on GLAmerge is to place a bat file in it with the following code and run using the bat file:
@[member='Echo'] OFF
"glamerge.exe" "_humanoid.gla" "inputfile.gla" -o
PAUSE
EXIT
