Need help with making custom animations

[thePhilanthropy]

So I played around with custom animations in 3ds Max for the last few days. All I want to achieve is to replace the vanilla hand to hand animations with my own ones. Mods like that already exist, so it's clearly possible, but it's still a mystery for me.

 

I read the only two tutorials that I could find about the topic and followed them step for step:

Seph Animation tutorial

Mr Cellophane's Tutorial

 

And while the animations I created seem to work as Idle Animations, they don't work as replacers. The vanilla ones are obviously being replaced, but they won't play ingame. Oblivion attemps to play them, even plays the sounds, but all my character does is glitch around for a second unable to hurt anyone.

 

The only thing I did different than in Seph's tutorial is that I didn't apply mocap animations, but made my own by hand. Comparing the files in nifskope I also noticed that under "NiTextKeyExtraData" one of the "Text Keys" seems to be missing in all my animations (the one that says "hit". I only have "start" and "end"). When I try to replace the NiTextKeyExtraData of my animations with one of Seph's, oblivion crashes. :pinch:

 

I'm running out of tricks here. Please help if you can! :thanks:
