The Making of Al Pacino Sculpt

My modeling process is simple. I start by creating a plane in the top lip, and keep extruding edges, maintaining shapes in both side and front angles, also looking at it from the perspective.

Al Pacino is my favorite actor, and I’ve always wanted to model him, and I finally did that. Here is the final image.

I first started off by collecting lot of images of Al Pacino in different angles –>

I chose an image from the movie “two for the money” (second image, top row), and started working on it.

MODELING

Here are a few snaps from the modeling stage. My modeling process is simple. I start by creating a plane in the top lip, and keep extruding edges, maintaining shapes in both side and front angles, also looking at it from the perspective. This method also helps in getting the edge loops to flow in the desired direction:

LIGHTING

I don’t like to complicate my scene by using a number of lights. I used three free area lights and two bright planes, with self illumination set to a value of 100. Since the main source of light in the image is from the right, I set the intensity of the key light to a high value, and also a mild brown colour. The fill light is a mild blue, and the back light is white.

Here’s a clay render

At this point, I had tried different approaches at achieving realistic hair like max hair, alpha planes and even sculpting it in zbrush, but nothing seemed to bring out the feel in the hair, I was looking at. So, I decided on painting facial hair and the hair on the head. Since, my final goal is a still image, any approach can be taken to achieve a desired effect

TEXTURING

The next stage was texturing. I spent a lot of time carefully laying out Uv’s since this is a very important step. If the Uv’s are not right, the textures tend to stretch. Here are my texture maps. I drew inspiration for the bump and specular maps from a German site.

The major time consuming process for me was getting the SSS shader to work perfectly, and also getting a good combination of the normal and the bump map, so that the final render looks like the level 6 sub- division in zbrush. For the SSS shader to work properly, the size of the model plays an important role. I decided to maintain real life proportions for the head.

RENDERING

Finally, I turned on final gather, and set the rays to 50, and the bounces to 3, and did several test renders. Take a look at a low resolution render with basic hair painted in.

For the final render, I used a high final gather setting of 1000 rays, 3 bounces. After a layer of paint over in photoshop, and colour correction, and more tweaking, I managed to end up in this final quality.

FINAL WORDS

A few tips overall, that I thought might be helpful.

  1. For painting small strands of hair, I take a 1 pixel brush and paint in strands. I then use the sharpen tool (shortcut R) over it, in places where I need shine in the hair, and those regions become sharp and coloured ( due to extreme sharpening), I then use the desaturate tool over the coloured pixels, and then use the blur tool over the desaturated strands. This method helps in achieving clean small strands of hair, quickly and effectively.
  1. I always use photographic reference, and I also have a big database before even starting the modeling process. I think research, is a very important phase in achieving good looking images.
  1. Concentrating on the minute details pays off in the final render. A lot of people may not even notice them, but the small details are the ones that really enhance the look of an image.
  1. I think its necessary to spend a lot of time on tweaking to get fantastic results, the more the tweaking, the better the results, and finally
  1. If you are doing a still image, anything counts. Feel free to take any steps to achieve the desired look and feel.

Thank you for your patience and encouragement.
