I have made a model with my.flare = off, and reproduce
the transparent problem similar to yours like the following
picture :



Fortunately, I found the following codes that was posted by
other forum member (sorry, forgot his name) and solve the
z-order problem.



Code:

---

material right_alpha_mat
{
  effect =
  "
    technique right_alpha1
    {
      pass p0
      {
          zWriteEnable=true;
          alphaTestEnable=true;
      }
    }
  ";
}

action right_alpha_acc
{
  my.material = right_alpha_mat;
  my.shadow = on;
}

---

If it still doesn't solve your problem, send your model
to MALABAR, may be he has a solution.

Good luck!
