Click on a part of the figure. Click on M. You see three pics in the upper right corner. Above them are two buttons. Click on the one that says Texture source editor when you pass the mouse over it. You get three windows. In the first and the last one are the pictures of the texture. Click on Copy beneath the first one, and then on Paste under the middle window. Click OK. Now, in the material editor, put a button in the A column under Bump Height and adjust the value to something that looks good to you.
