Hi everyone,
After months giving up, I decide to fight again with the boneWeight and animation in Noesis.
The files come from jx2 - Kingsoft.
Mesh and bone are loaded correctly (or as I think so) but bone weight isn't.
There are 3 issues:

1. I do not know how to use functions for bone weight in Noesis in my case.
2. Why is there a 4x4 Mat for parent bone under each 4x4 Mat for each bone, or maybe I missunderstand about its role. See below for reference.
3. How to test for the weight and bone when I have no animation file, is it anyway to create a simple animation for testing purpose?

Hope someone could help or give hints. Many thanks.
Here is the file structure:

Quote:

The ksword3d models look static - very simple, vertices 3 floats, normals 3 floats, UV 2 floats 1 long, triangle strips?

I add structure of bone as below:

Code:

bone offset 4 bytes - byte 188th from the beginning
After jumping to bone offset
number of bones 4 bytes
char bone-name 30 bytes
char parent-bone-name 30 bytes
int number of child bones 4 bytes
char child-bone-name[] 30 bytes
float transform-matrix[4][4] 64 bytes //need to be inversed
float parent bone transform-matrix[4][4] 64 bytes //need to be inversed
int number of vertex connected to this bone 4 bytes 
int vertex id[] 4 bytes 
float weight[] 4 bytes // weighting information corresponding to vertex id
