Part 2 goes over how to generate hair, clump them, add variations and render it in Mantra. There is also a separate introduction series, for beginners, to go over basics on grooming in Houdini. If you have missed Part 1 or the introduction to grooming, you can access it here.


Chapter 10: Hair Generation

We will begin by painting attributes in order to generate our hair; we will paint density maps. We will use a custom material to better see on the skin, where we will paint the attributes.

Chapter 11: Extra Combing Tips

Let's clean up our scene, since we have progressed with our groom results. We also will make some adjustments to the groom on the ear area, to closer match some details in our reference.

Chapter 12: Rendering Set Up

We did some more groom adjustments to give more guidegrooms to Barry Bacon, so we have enough detail from him to look good. It's done with the same techniques as we have already covered. Barry Bacon is ready to start rendering in Mantra.

Chapter 13: Model Update

Our first test render is done, but he looks pretty different from the reference. We also have new geometry to use, so let's see how we can transfer the groom and bring it closer to our reference image.

Chapter 14: Clumping Structure

We will see how to refine Barry Bacon by splitting the groom across his face, separate from the top of the head and ears area. We just need to pay attention to not make any obvious seams, to ensure a natural look. We will do so by using masks to help the different areas blend together.

Chapter 15: Adding Variations

You may have been wondering all this time, where are the noises? Here they will come as a last part, after establishing clump shapes and breaks.

Chapter 16: Ears and Top Head

Now we have the groom on Barry Bacon's ears and top of his head, but without shading at this point. Let's have a look at the setups of both - they are rather similar. There are variations in width, parting lines, fly-away hairs, density, clumping, length and a bit of bend.

Chapter 17: Shading

Let's see how we set it up with the hair shader for Barry Bacon. There are separate hair materials per areas of his face. We will use attributes to bind and control specific things like root colour, specularity, saturation, tip colour, and more.

Workfiles include Barry Bacon geometries, *.hip file and reference image.
