@Zain,
are you sure problem with texture less soldiers is the actual texture (alpha etc) and not the folder structure its in?

I had the metalic soldier effect when trying to make changes in mod-folder. Think battle_models.modeldb and new textures have to be in main folders not mod-folder (unless there's fix for that) and use the --io.file_first switch

to double check before you play with texture too much, back up your version and copy and re-name an existing texture to it - to make sure that appears in battle.

(suspects she doesn't really know what she's talking about so runs away to hide in RTW section again....)
