## Copy Stamping and the Foreach Loop

This tutorial describes how to use point attributes to influence upstream input nodes, first using the traditional Copy Stamp Node then again using the Foreach Loop nodes as recommended by sidefx. Then it takes an in depth look at the other uses of a Foreach loop: Looping by pieces, by number, and fractals. (77:38)

## Volumes and VDBs

A guide to the different types of volumes in Houdini, and some basic networks for common uses of volumes in procedural modelling

## Attribute Transfer Node

This tutorial looks at the Attribute Transfer Node which passes information from one object to another based on their position in space. It uses a network that places tree roots on a hillside to demonstrate various ways in which attribute transfer can be used to create realistic procedural scenes. (54:00)

## Setting Up Digital Assets

Steps to create a Digital Asset Select the nodes you want to include in your Digital Asset Right click on a selected node and go to Actions -> Collapse to Subnet Right click on the subnet and go to Create Digital Asset Name your asset and click Accept This opens the Edit Operator Type Properties […]

## Group Nodes

This tutorial looks at how to create and use groups in Houdini. It covers the group node, the group range node, the group transfer node and the group combine node. These are demonstrated by the creation of a chessboard which is controlled by chess notation. (30:19)

## Scatter Node

A look at the Scatter Node which is used to place random points on a surface. It covers different ways of driving point placement (point counts, textures, density attribute) and dives deeper into working with attribute VOPs. It demonstrates how this node can be used to create a realistic distribution of vegetation. (35:58)

## Merge Node

A short tutorial on how and when to use the merge node, and how you can use groups to access individual sources after they have been merged. (10:04)

## Geometry Primitives

An in depth look at the Geometry Primitives that can be used as basic building blocks in Houdini. This is a very practical tutorial that will tell you everything you need to know about the different types of geometry you can create and when you might want to use them. (23:58)
