Glad it worked.
In fact it was pretty simple.
Start by checking the GMDC Here you can see which subset your model use - no matter if it is a slaved mesh or a mesh with own (internal) textures). If a subset is not here, your mesh doesn't use it. In this case the subset name is
sculpturechi_chromeThen check SHPEAll subsets defined in GMDC must be defined here as well (don't forget to check if they are spelled correct).
Then check TXMT and MMATTo make things work the right way you must have an MMAT to match your subset
sculpturechi_chrome and the
name of the MMAT must match the
stdMatBaseTextureName in the TXMT.
In your case there is 3 TXMTs - one related to the
sculpturechi_chrome subset:

But there is only 1 MMAT and as you see this is NOT related to the
sculpturechi_chrome subset. In fact it is related to a non-existant wood subset.

So I made 2 changes in the MMAT:
- I changed the subset name
- I changed the name of the MMAT
You can edit it by clicking the textline i the left side (where the red boxes are) and then the text will show in the right side of the screen. Then you can make your changes -
DON'T FORGET TO COMMIT.
After you have made the changes then go to: Tools -> Object tools -> Fix Integrity and press OK.

Then save and close.
Here is how it looks after I have changed it:

That's all

That was my first tutorial ever, hope you can use it.
Kind regards, Helle
