Ok devs, you are up, the textures are good.
But your armor is still not riged
This is what causes the lines.
you must rig theses mesh:
-song_armor_ba
-song_armor_da
-song_pifeng_c
-song_tiejia
And their respective lods.
Or you can directly use the brf I provides, that contains exactly the same thing as you but in functional state..
For players, my files are always functional, you can use them with the last update..
