Animation Edit Help: Retractable Bridge

[Fyn689]

Hi there people, I'm absolutely new to the Skyrim Modding scene as a creator, I have my years as a user.

I started playing Skyrim again and noticed the awful lowering animation of the retractable bridge at Helgen, which can be found in other Nordic dungeons as well.
I located the file, it's name is norretractablebridge01, located under:

...meshes\dungeons\nordic\clutter\retractablebridge

 

I have been looking for tutorials, I don't like to ask without searching first, but I don't know how to continue.

I have a BSA extractor, got the .hkx files already, I got the Creation Kit and 3DsMax, NifSkope, the hcxcmd tool and the Havok Preview tool as well.

 

I don't expect you to give me a tutorial here, but how can I open the lower.hkx animation file in 3DsMax?
I know I can convert hkx to .kf files, then load a .nif skeleton and then the kf animation but the skeleton file for the bridge is hkx too? At least that's what I found.
There's something I'm doing wrong, of course.

TL;DR:

- I want to edit the lower.hkx animation of norretractablebridge01 in 3DsMax.

- I have BSA extractor, Creation Kit, 3DsMax, NifSkope, hcxcmd and Havok Preview Tool

- I don't know how to load the bridge in 3DsMax to edit the animation, and how to get it back into the game.

- Tutorials you can point me to?

Thank you.
