Distorted texture in 3dsmax7

[manu7777]

Hi,

I have a little with 3dsmax7 and skinning :

I want to create a shoulder protection named sode on a samurai armor. So i create a box divided in 3 sections in length and 5 sections in width. I resize my box and i apply the samurai texture to this box. Then, i add the Unwrap UVW Modifier and apply box mapping in the normal mapping menu like that :



So it gives the following render :



Then, i link the sode to the arm bone, export the model with cas exporter and close 3dsmax. Then i reopen 3dsmax and import the model and zoom on the sode it gives the following render :



The texture is completly distorted ! How must i do to keep the texture well-placed on the sode like in the first result and fix the problem?

Sincerely.

Manu
