Unfortunately your edited textures of T3 (by Darth Sapiens) have no Alpha channels, and consequently the astrodroids are bereft of their nice alloy sheen. So I wonder if you could get around to restoring those Alpha channels to the textures as it would be a great improvement.
P.S. I would have done it by myself, but for a reason that eludes me I wasn't able to open the original DDS texture of T3 made by Darth Sapiens (nor any other DDS textures made by the Darth, for that matter), which had frustrated my intention of transferring the alpha channel to your modified textures.
