I just tried to import DAZ leg armor with more than 20 materials. I could not use the function to merge materials, because there were two texture sets for both legs (L & R) which VaM does not recognize. As soon as the Clothing Creator loads the materials, the side tabs bar is filled with 20 material entries and all other tabs like "physics" will be superseded. 20 seems to be the max entry number. A second row appears, but does not show any entries. No scrollbar or anything else appears, rendering the Clothing Creator useless. Once clicked on one of the material tabs, you could not get back to the main creation menu to cancel or redo the creation. It stays unusable till reboot.
