Unreal engine2 analysis-lineage2 bone Animation

What is it like? I haven't published any essays in a quarter ...... Why? Because nothing has been made. Alas! It's hard to learn things. I was trying to figure out the skeleton animation and try again later. However, I'm afraid I have been rolling around for more than half a year. I am deeply impressed that the game is not a single task. How long does it take to figure out all these technologies? Life is short.

I am deeply impressed with my feelings, but I still want to learn it. However, although it is already an age of information explosion, it is really difficult to find technical articles. There is basically no Chinese application for finding a Z, and there are only a few English words, most of which are matrices. Although matrices can be exchanged with semicolons, they are still different. The animation in the Unreal Engine records the rotation information of nodes by using the Quaternary element. It took me a lot of time to figure out how to do it. In the end, I converted the Quaternary element into a matrix for transformation.

These two images are the skeleton animation information of meshanimate extracted from the unreal ukx file.

 
The meshanimate of the dark precision mm actually contains more than 70 animation groups. Some naked bones do not know what the movements are. I feel like I have never seen them in the game. What is hidden? Look at the picture below. Isn't it like dancing in street dance?

 
This part of animation is really difficult, because there is no ready-made materials for reference, it is difficult to find relevant materials. Depressed. I don't know when to make the skin work.
