The addon will not convert duplicated images

if you have two textures with the exact same name and extension, only one of these textures will be converted, you will be able to check what textures were duplicated and not converted in the log file.

In most cases, duplicate textures will happen when you load the same material or textures twice, and if this is the case, you have no problem, is the same image, so when replaced, the converted images will be the same.
