This series of videos focuses on a typical UV workflow in Houdini 9. Learn how to create projections, edit UVs with a variety of tools, save out UV maps, and apply textures. Please download the project files below to follow along with these Houdini 9 texturing lessons.

Simple UVs: Start with this lesson, it quickly covers the major steps we will use in the subsequent 4 lessons. This is a good overview showing the tools and workflow that will be repeated many times. We define a particular workflow and create multiple UV groups to account for the whole model. We also explore the use of visibility sops to control the areas that we wish to work with.

We leave the example prepared for subsequent lessons which will look at the internal workings of the uvpelt sop and roughly editing the uv's. Creating a Material: This lesson provides an excuse to cover how to create a material from scratch.

This material will be capable of applying a texture to our uv groups. Creating the material basically follows the process that was used to create all the materials in the default gallery. Trust me, it will be fun. Rough Edit of UVs: We encounted a couple of problems in lesson 3 that we will rectify in this lesson and then carry on with roughly editing each uv group with the parameters in each uvpelt sop. Refining Uvs: At this stage we have the opportunity to refine the uv's in each group with uvbrush and uvedit tools.

We also need to consider how to manage this editing process, so we explore one possible way of doing that. Due to Houdini's flexibility there are many ways to approach the same needs.

We explore how to save out uv maps as templates for use in a texture painting application. Near the end of the lesson I propose a stage of editing whereby the geometry is saved out from Houdini 9.

Higher and lower precision storage. Indexing and limit variables. Attributes are named values stored on vertices, points, primitives, and objects. Point color, position, UV coordinatesspline weight Wand normal, for example, are stored as point attributes. Houdini sets some point attributes that you can use in expressions. For example, you could set the per-point color based on the vertical position PY of the point.

Certain attributes you can set manually and if they're present they will be used by Houdini. For example, the dynamics solvers and rendering engines will often use certain attributes on the geometry if they exist. You can also set your own custom attributes to be used by your node expressions, scripts, exporters, and so on.

The surface nodes in the Attributes group of the tab menu set different types of attributes. You can also set or create arbitrary attributes using the Attribute SOP. Particles also have attributes, and attributes are very important when geometry and particle systems interact.

For example, particles emitted from geometry inherit by default the attributes of the point from which they are emitted, and you can create interesting effects by transferring attributes between surfaces and particles using the Attribute Transfer POP.

You can attach attributes to vertices, points, primitives e. When you merge two or more branches in a geometry network, if a detail attribute with the same name exists in multiple branches, Houdini uses the value in the first branch.

If the attribute is a string array, Houdini merges the arrays. When two components in the same geometry have an attribute with the same name, the attribute on the "lower level" of geometry is used, so:.

Most surface nodes have a Group field that lets you enter a named group or a pattern to select which components the node should apply to. This field recognizes special syntax that lets you select components by the value of an attribute.

See the section on manually specifying groups for more information. Intrinsic attributes are computed values derived from the geometry that you can access as if they were attributes. For example:. The command line utility ginfo -I prints a list of all known intrinsic attributes.

You can show intrinsic attributes in the geometry spreadsheet. By default they are not shown.

If you are viewing geometry at a component level that has intrinsic attributes, you can use the Intrinsics menu to show all intrinsics or choose which intrinsics to show in the spreadsheet. The Inspect tool can show which intrinsic attributes are available on the inspected geometry.You can also go to the GitHub page to get more information about each tool.

Texture Sheets Create sprite sheets from your animations and customise the data stored in each colour channel. Vertex Animation Textures The Vertex Animation Textures ROP will export a mesh and textures to be used with a realtime material that can playback complex animations for cloth, rigid body destruction, fluids and particles.

Destruction Cleanup Prepare rigid body simulation results for export, reducing redundant geometry, cleaning normals, cleaning attributes. Skinning Converter Skinning Converter is a SOP that can convert any non-changing topology deforming mesh sequence into a bone based animation.

Motion Vectors Using the velocity field or point attribute this tool will generate 2D motion vectors which can be used to retime motion in a shader. Flowmap This utility tool sets up a flowmap template on your input geometry. Flowmap Visualize A high quality realtime preview of a flowmap texture in the Houdini viewport. Flowmap Obstacle The flowmap obstacle SOP allows for easy modifications on the flowmap based on geometry.

Impostor Texture The impostor tool creates texture sheets to fake 3D objects in your game engine. Niagara Impacts Extract impact points from a rigid body bullet sim and add attributes required for the UE4 Niagara data interface.

Static Fracture Export The Static Fracture SOP takes static geometry data from sop level, and separates them into newly generated geometry containers on object level. Disc Generator Create a disc mesh with uv's with controls for slicing and uv coverage. ZBrush Bridge GoZ is Zbrush's fast file transfer feature that lets you send meshes between Houdini and Zbrush seamlessly without having to deal with file paths or extensions.

Delight Remove light and shadow variation from photogrammetry textures. Maps Baker Generates textures bakes from a high resolution to low resolution model at near interactive speeds. UV Transfer Transfer uv's between a source and target geometry.

Building Generator Utility Create base modules to use with the building generator, as well as override base module behavior. Cable Generator Given a curve that represents the high 'pin' points and low 'sag' points of a cable, this sop will generate sagging cables, with user definable cable count, shape, colour. Curve Branches Scatters curves over curves, with many intuitive controls to go from clean geometric branches to organic vines. Duplicates of this sop can be chained together for recursive growth, approximating the look of L-Systems but much more controllable.

Dirt Skirt Create a geometry 'skirt' where an object and ground plane intersect, to be used as a soft blend in a game engine. Lot Subdivision Divide polygons into panels.This Houdini 9 software video series focuses on examples of when and how to use Attribute Transfer.

Part 1 covers Attribute Transfer One Point: A very basic example of how to use the attribute transfer sop, by using a single point to transfer a colour attribute to a grid.

Part 2 covers Attribute Transfer Line SOP: Continuing from the first lesson, using a line sop and transfering rand point colours to the grid. Part 3 covers Attribute Transfer Point Switches: A further addition to the previous two lessons with the introduction of a point sop to generate random colours and switch sops to manage the display of multiple inputs.

Part 4 covers COP Ramp "tex" Function: Expanding on the flexibility of the point sop by introducing the "tex" function to read the colour values of an image and distributing colour values to points.

A ramp is used in a composite editor. As well, there is a brief discussion of the importance of node ordering. Part 5 covers: Attribute Promote Mountain Normals: An introduction to the attribute promote sop and illustrating how transferring normal attributes from another object can influence how to control the lighting of a surface. By the end of this Houdini 9 tutorial you should be comfortable transfering attributes from within any part of Houdini 9 be it modeling, animating or working with particles or other effects components.

There are easier ways to use Houdini — commonly used nodes can be set up automatically using shelf tools, and useful networks are now embedded in higher level nodes — but I believe that to be able to fully harness the power of Houdini it is important to understand the basics. I have been learning Houdini sinceand have been using it in production for the last 5 years. I also have a degree in Archaeology and have completed several 3D projects for the British Museum. More from Susie Green.

Hi Susie. I've been fiddling with Houdini from a personal perspective since As SideFX has been enhancing their modelling toolkit over the last few years I'm starting to lean from 3ds max to Houdini in this department, so videos like this is extremely good to watch as you said about how hard it is to make a UV video interesting - I understand that. Anyway you passed on some very helpful tips and tricks that I was unaware of on the UV front, so thank you for your effort.

It will be interesting to see what you come up with in the future as laying out UV's is an area most people shy away from. Thanks again and all the best! Forgot your password?

Choose language.This training is primarily aimed at users ranging from a beginner to intermediate level. The main purpose of this training is to help users understand the texture and material building system in Houdini.

The topics covered in this training begin with a basic understanding of using colour maps in Houdini. We then take a look at all the various patterns and noise maps that are built-in to Houdini and use them for generating textures and displacement.

As we progress we also begin learning how to modify and distort UV maps to modify textures and also use the For Loop to generate complex repeating and random patterns. We end the lesson by building a simple custom shader using the base level physically based nodes that are available in Houdini.
