BRRES model import looks like melting?

[tshr_]

I couldn't find any thread about this issue, i hope someone there can help me.
I want to import some brawl models + bones and animations using a 3ds plugin to import psa and psk files.
so using BRRES I export the models with their own animations.
But some models look like this when I open them with BRRES viewer



does anyone have this same problem?
have anyone found a solution?

thank you
