Another way that I could use to create the effect of the bumps on the skin was to select 'Cellular' in the Bump map box. Here there was lots more parameters to play around with.
I found that the Cellular had a very grainy finish. It didn't matter how much I played with the different parameters it stayed quite grainy and the blacks showed up a lot. So I decided to make my own bump map using the flattened face image in Photoshop.
I started by adding a mid tone grey colour to a layer and then using the 'fill' to add it to the foreground. I then used the 'desaturat' in the 'Image' drop down. Then I adjusted the 'Levels' so that I got a nice representation of the colour values. Next I went into 'Filter','Other' and 'High Pass'. I then needed to next get rid of the embossing effect around the ears and chin with the 'Clone' tool.
Once this was done I went back into Max and in the bump section I selected 'Mix' which will allow me to have two maps for the bump. The first was the map I have just made and the second was the noise map I liked from before. Here I used the 'mix amount' button to blend the two maps together.
These maps compliment each other quite well they were nice and subtle from a distance but it looked quite realistic when looked at closely. This would be my finished face texture.
