Okay, after a lot of tests, I can tell you the truth : I'm very bad with XSI !
I try since 2 month to create a character with the UT3 skeletal, but I fail always. My character is rigged on the skeletal, but my export don't work properly. I get some errors.
The errors are :
Export from XSI
Import from UDK :Invalid number of physique bone influence (0) for skin vertex 0 (1, 2, 3 ... 97).
Warning skeletal mesh has no vertex influence
I don't understand the error, because the animation test work fine :
But I think this is my organisation in the scene who are bad :
Anybody can explain to me how to export correctly my character ?
I think I miss some details, but which ?
