The model cant be replaced, and even if it could that cost would be in the 10's of thousands of dollars. I did however cover it in baby powder. Whille it work a little better ultimately it still failed. Now it just smells nice. Im now trying something new, very aimiliar setup to a mo-cap studio setup. I took about 400 pictures of it using all the different modes in kscan3d. Im currently going through the process with Meshlab.
