Bump map

Go back in to Photoshop and start the ear texture again. Next is to do the bump map. I have created a gray background and on the texture layer, click image, adjustments and select desaturate to lose the colour information. 

Go back to image, adjustments and click level. Drag the first and the last tap right at the edge.

Go to filter, other and click high pass, and set the value to 2.1.

Go back to 3d max, open material editor and apply the bump map at the maps panel, then set the value to 5.
 

Next task is to clean up the bump map. Select the clone tool and go around all the edge, so we can remove the seams. 

To make the skin texture more realistic, I go back to 3d max material editor, go to bump map and from the bitmap button choose mix, and keep the old map as sub map. At the empty colour 2 chooses noise.
 

Inside noise, choose noise type fractal and size 0.101. Go back out to the mix parameters and have the mix amount to 100.  

After render the skin still need to be improved, so I have to go back to the noise map and increase the tiling of x and y to 3, so as you can see above, the skin is more smooth. 

Next is to change the mix amount, so it goes well with the skin.

Then I need to add detail to the lips.

Back in Photoshop I have decided to add more detail to the lips, so I create a new layer, select the brush tool, turn the opacity down to 20% and use white and black colours to draw lines on the lips, and use the blur tool to blur out the lines. 

After adding detail to the lip using bump map.
