Hi
So I wanna change and add some markers to the default master chief. I import the model on 3d max I change what I wanted after that I export it as a jms then I compile it with tool and change it in the biped tag. But when I compile my map it tells me that the animations and the new model don't match so it won't animate.

My question is:
How can I change something small on a character's gbx model then re export it, and use it as normal? I just wanna change some markers :(

Open your gbxmodel with Kornman or OS Guerrilla (if you don't know what they are, look in the website), check the "Node List Checksum", then open the animation tag, scroll down until you see "Node List Checksum" again. Copy that number and paste it in the gbxmodel.

Alternatively, you can open the jms in Notepad and do the same thing

You can set the node checksum to 0, don't have to copy.

THANK YOU SO MUCH!!!!!

It worked !!!!
now my question is, if i put this checksum in 0 it will have secondary consequences ?

No.
