Merge Packed Texture Set Utility (free sbs+sbsar)

The Merge Packed Texture Set Utility is a Sbs/Sbsar file that allows you to combine different texture sets and automatically packs the greyscale channels into a single RGBA texture. Usually being a tedious task to do manually in programs like Photoshop, this little tool aims to make our life easier when it comes to multiple texture sets and packed textures.
