[TEC] Help with WIP unit visual damage (?)

[VonDos]

Hi everyone!
In those days i'm working on a new Queen Elizabeth model.
I've finished 3d model for civilian version, i've imported all parts with 3ditor, created damage profile, and tested in SH3.
I've found this strange bug: when a torpedo hit the hull, sometimes damage textures appears. Sometimes doesn't. Randomly.
In both case ship slow down and take damage points \ sink.
I've tryed to rebuild files, re-import models, clone files, no results. This is really frustranting.

This is the Wip unit, nearby her parent unit (Queen Mary):

Same at night:


Is there anyone who can help me solve this situation?

Best regards,
Vd
