Don't get me wrong, but i cant get what is my part here :)

What are your plans and ideas?

You can follow that:
http://modding.scssoft.com/wiki/Tutorials/SCS_Workshop_Uploader/How_to_upload_new_mod%3F

if you want .zip your mod and give the link to can look what is the structures inside
and what can be the problem

add me like friend if you dont want to post link here

hmm check the values of that .mat in blender again, maybe it have something wrong

open that file "a3e45782c306590f7bb531b1e4fd09185c5ed3.mat" look how is inside
i guess it is the shadow texture for trailer :)
then check all setting for that in blender
be sure .tobj go to right texture .dds or .tga

sometimes when you ave more then one look you need to do it for both looks

i cant say much, becouse idk what is the mod and what you do :)

what you do with that file ui_shadow.pmd? You edit it in blender too?

P.S open texture .tobj file in notepad++ and read what is file name
