What You’ll Learn

Behind every great operation, there’s an important selection and Houdini gives you lots of options for making them directly in the viewport. Even though these direct selection tools are really powerful they don’t get much airtime. In this course we give them the attention they deserve. We’ll give you all the knowledge you need to make your selections quickly and efficiently, and in a classic interactive way. It’s all about building essential skills for direct modelling and editing in Houdini.

By the end of this course, you’ll have a deep understanding of:

  • The need-to-know geometry selection tools, modes and hotkeys
  • The significance and nature of connected geometry in Houdini
  • The select by normal tool
  • The advantages and disadvantages of groups versus string attributes for saving selections
  • Using the groups and attributes list to inspect and select geometry components
  • How to get the most out of Houdini in an interactive mode (rather than procedural mode)

Course Syllabus


Let’s talk details

Section 01

Selection tools, modes and options

If you’ve been with us on this geometry adventure so far, you’ll know that we’re all about building the proper foundations. So in this first section we’ll show you core geometry selection tools and hotkeys that you just can’t live without. Prepare to level up your speed and accuracy when working directly in the viewport.

Noise Versus Random

Lessons

1. Selection tools and types
2. Selection options
3. Intersect and toggle select modes

 

 
3 Tutorials   13 Minutes

Section 02

Loops, rings and applying operations to viewport selections

Houdini’s a procedural powerhouse, but it can be tricky to work with it in a classic interactive way. It’s way easier if you know how to push its buttons, so consider this section a button-pushing masterclass. It’s full of vital info and techniques to help you understand how to work with Houdini in its much misunderstood interactive mode.

Distribution & Density

Lessons

1. Selecting edge loops and rings
2. Selecting primitive and point loops
3. Shortest path selections
4. Secure selection and the edit node
5. The importance of cursor position when using hotkeys and the tab menu
6. Viewport selections and the radial menu, repeating operations, and comparing interactive nodes to procedural nodes
7. Working with cook selections, and reselecting for operations

 
7 Tutorials   31 Minutes

Section 03

Converting selections, pattern selections and boundary selections

You now have a heap of different selection techniques and hotkeys under your belt - time to put them into practice. Classic hard surface modelling in Houdini coming right up. We’ll dive into a couple of exercises that will show you how to accomplish classic direct modelling with speed in Houdini.

Correcting, Adjusting & Compostiting Attributes

Lessons

1. Converting selections, growing and shrinking selections, and selecting boundary components
2. Practical exercise: hard surface circular indents
3. Pattern selection
4. Practical exercise: hard surface hose Pt1
5. Practical exercise: hard surface hose Pt2 - edge cusping

 
5 Tutorials   24 Minutes

Section 04

Connected geometry

Houdini’s unusual in that we often work with lots of different pieces of geometry all bundled into a single container. These uber objects make the concept of connectivity all the more important. Here, we’ll explain how 3D connectivity’s controlled by splitting and fusing points, and we’ll show you how to visualise and select islands of geometry based on connectivity.

Attribute VOPs and Attribute SOPs

Lessons

1. Flood fill selection
2. Controlling 3D connectivity
3. Visualising and selecting 3D connected geometry

 
3 Tutorials  15 Minutes

Section 05

Select by normal

You learnt the finer points of normals in earlier Geometry Essentials courses, now it’s time to get those vectors to do the heavy lifting for you when making interactive selections. This mighty selection tool can work in a number of different ways. We’ll show you how to use which mode and when so you can get the most bang for your buck. Or, more accurately, the most points for your click.

Controlling Random Value Distribution

Lessons

1. Select by normal pt. 1: default mode
2. Select by normal pt. 2: contiguous selections vs all matching normals
3. Select by normal pt. 3: static reference normal

 
3 Tutorials  17 Minutes

Section 06

Creating and selecting groups

Like attributes, groups are a cornerstone of working with geometry in Houdini. They’re a simple but powerful way of saving selections of geometry components. Groups really shine in procedural workflows (we’ll get to that in the next course) but they also bring speed and convenience to your interactive work, too. Here we’ll show you essential tools and techniques for creating, visualising and selecting groups directly in the viewport.

The Scatter and Align SOP

Lessons

1. Visualising and selecting groups
2. Creating groups from viewport selections
3. Promoting groups
4. Working with groups in direct modelling workflows

 
4 Tutorials  21 Minutes

Section 07

Groups versus string attributes

We have two different ways that we can save named selections in Houdini: groups are one and attributes are another. In this section, we demand that they fight to the death. Well, not quite... But we will do a comparison. You’ll learn the advantages and disadvantages of groups versus attributes - and when to use one over the other.

Testing and Optimising Networks

Lessons

1. Saving viewport selections using the name attribute
2. The efficiency of the name attribute
3. Paths and selection hierarchy
4. The path attribute
5. Groups for ad hoc selections

 
5 Tutorials  18 Minutes

Section 08

Data driven selections

If this section had a subheading it would be “Work data, not harder”. We’ll skill you up in the fine art of getting the data to do all the toil. We’re not talking about procedural selections just yet, though. These are techniques for using the data on the geometry to make interactive selections directly in the viewport… just with far less clicking than you’re forced to do in other applications.

Testing and Optimising Networks

Lessons

1. Working with imported geo - OBJ and FBX
2. The shop_materialpath attribute
3. The inspector (and find node tool)
4. Controlling primitive visibility
5. Selecting by integer attribute
6. Selecting by float attribute
