Need Help With AnbMaker Please!

[Shinobz]

I really hope this is the right place to post this, I'm sorry in advance if this is not the correct area.

I'm attempting to use AnbMaker for my first time today, with an animated .FBX file I've created in Blender using Axel's RTN model & bones (B_EX110_RTN). For some reason, when trying both the "anb" argument and the "anb-ex" argument, it continuously throws the following error:
"FATAL ERROR: Object reference not set to an instance of an object.
at OpenKh.Command.AnbMaker.Utils.AssimpHelper.FlattenNodes(Node topNode)

at OpenKh.Command.AnbMaker.Program.Main(String[] args)"

I've tried multiple sets of export settings, and my Windows 3D viewer opens the .FBX files and plays the animation fine, so I'm not sure what could be going wrong... I've read the documentation on the OpenKH Index but didn't see anything mentioned about that in specific. So at long last, I come to ask for help from the OpenKH Team or anyone else who can help me solve this issue! :)

I appreciate your time and assistance in advance!

OpenKh.Command.AnbMaker.exe anb-ex --root-name "bone000" animation.fbx

Use that. Make sure the bone name in quotes is the name of the model's root bone. "animation.fbx" should be the name of your animation, of course. Hope this helps.

I appreciate the help, but unfortunately it is still not working, I receive the same error. I'm now entering: "OpenKh.Command.AnbMaker.exe anb-ex --root-name "bone0000" attempt.fbx"
(one extra 0 in bone root name since Axel's root bone is "bone0000", I also tried with only three 0's to make sure".
Of course, my "attempt.fbx" file is located locally in the OpenKH folder and it is recognized.

Before the error message, it tells me that it begins writing the file, I'm not sure if that's of any significance:
"Writing to: C:\Users\Oshin\Desktop\KH2FM Modding\Tools\openkh\attempt.anb
FATAL ERROR: Object reference not set to an instance of an object. ......."

I also tried using "bone0001" and "armature" as the root name but still had no luck :/

I've attached the .fbx file below for examination, just be prepared to cringe at the awful "wave" animation I made for the sake of testing this lol.

Thanks again!

Okay, a quick question- Did you make sure it was "Bone0000"? It's case sensitive. Also, be sure you disabled "Leaf Bones" and "Key All Bones" when exporting the fbx. I did so and it worked for me. You might've just not properly capitalized "Bone".

[Shinobz]

Thanks so much! It was the "Key All Bones" option I left checked, and also I didn't capitalize "Bone0000"!
You freakin' rock and I can't stress this enough! 👍
