I am sorry to say that there are no Miki 3 texture files included with the Miki 4 bundle. Glitterati3D made a very big mistake in suggesting where to find those files when they don't exist. I have a Miki 3 runtime folder that I set up when I purchased her years ago. I would suggest looking through ShareCG for any Miki 3 characters. With luck, you might find some with body textures. Unfortunately, the existing texture conversion programs do not convert for Miki 3 and 4.
