Do this interactively and customize the buildings via Assets for new and unique structures…. In this tutorial I demonstrate how to import map data and create Virtual Cities from around the world.

Python scripting could be of a great help, especially when it comes to redundant things that if done manually would take ages. In this tutorial you are going to learn how to use python in Houdini. Using strait forward examples, you will understand how to use this feature and what is needed for it to work correctly. By guiding you step by step into achieving the above result. And the different possible solutions and optimizations that Houdini offers.

Assembling your City - Part 1: Procedural Building Modules

Many subjects are tackled in this Houdini-Mantra shading and rendering tutorial, such as Materials, Rendering tools, Direct and Indirect lighting, Global Illumination, Displacement, details about Mantra and others. In collaboration with cmiVFX, sidefx training partner, I released an intro to particles in Houdini training course.

Details Now you can jump right into particle animation with this comprehensive guide for entry level Houdini artists. No matter if…. In this 3 parts tutorial I will explain how to transfer the colors of an image to particles in Houdini, then i will talk about creating an initial state file to end up using it in a particle simulation to blow the image away.Benefit from production proven workflows while also getting an in-depth explanation of why things work the way they do.

Generating cities or street level data previously would take weeks or months and a team of artist.

There is an increasing demand for creating virtual cities for film and broadcasting projects, however getting a city built and prepare it for deployment is not an easy task.

The time and resources spent can be very costly. This tutorial provides an innovative solution to automating this virtual city generation process and reducing the time and the resources allocated considerably. Nothing is better than Houdini for such projects, but this course is not limited to just this application, the techniques demonstrated here can be utilized with any other 3D application and it will work the same.

There are many techniques that can be used to generate city patterns; in this video the one demonstrated will be how to use the data of a real life city, exported from openstreetmaps. The city data used is the same kind of data used in GPS devices, while the GPS uses it to give routing information and data, here the data will be used to generate 3D cities. The first step in the process is to identify what city will be the target of the project.

An overview will also be given to learn more about this data and its structure. The exported data must be parsed into Houdini and Python scripting is the method of choice with this project.

The data will be explored in more detail and the utilization of a Houdini Python SOP will write the corresponding code that will parse the first main part of the data and transform it into Houdini points. Resembling our city of choice. Combining the points already created in the previous sections with the second main part of our OSM data, this section will dive deeper into the data analysis. Covering more detail in the parsing and coding, the ability to be able to reconstruct the pattern of the city and treat different data types differently, like the roads, parks and buildings, will be discussed at lenght.

At the end of this section the main skeleton of the city will be constructed and ready to be built upon. Begin filling the city with buildings, utilizing the OSM data. It is very important to mention that this data does not contain everything; in particular it does not contain all the buildings, a lot of them will be missing. The city will then be filled completely with the respective buildings.Workflows created using PDG use TOP nodes that generate work items that distribute tasks to either your local computer or a larger compute farm.

The TOP network lets you determine how different work items depend on other work items and how each of them is contributing to the final output.

This information is easy to visualize in the node graph which can be used to define how you want data to flow through your network. TOPs lets you build workflows that can be used to automate, analyze and scale your pipeline. In this lesson, you will use TOP nodes to take a city map, create buildings for each city block and then grow this system to handle more complex buildings and larger city maps. Houdini artists will probably know how to do this in SOPs, but by using TOPs, you can learn the PDG workflow while creating a system that can be easily scaled to distribute multiple tasks to an external compute farm to process in parallel.

To make this work, follow these alternative steps to avoid this licensing issue:. He has created lots of learning material and demos designed to help artists understand how going procedural with Houdini can benefit their work. More from Robert Magee. When I get to the create city grid hda step. It seems to error out. I don't know what I am doing wrong. Can you save your work so far and zip up your project directory and send it to me rmagee sidefx. Hi, nice Tutorial thank you very much. Do you have Image Magick installed?

If so then please send me your project files zipped up and I can look into it for you. I've fiddled around with the settings a lot but I'm not getting anything from this node in the geo directory.

I've checked the output path is correct. I had that issue when I was testing the tutorial - it says to do it in Part 4 step 1 but I missed that step anyway. That's the problem!!

I'm sorry if it's a rather stupid question because i'm fresh new to Houdini and I have squeezed all my brain juice out trying to figure out why. Thank a lot in advance Hi, thanks for the tutorial. Awesome technology, but I am following this tutorial to the point of cooking the HDA Processor. The work item display turns red with no further error messages. Just saying: "failed 1" in the info box.

The node cooked, the work items display became green as normal and short before finishing changed to red. There are lots of little gotchas when working through PDG. I would need to see your network to see how to fix things.Houdini is built from the ground up to be a procedural system that empowers artists to work freely, create multiple iterations and rapidly share workflows with colleagues. In Houdini, every action is stored in a node.

The ability for nodes to be saved and to pass information, in the form of attributes, down the chain is what gives Houdini its procedural nature.

While the nodes are what makes Houdini unique and give it power, there are lots of viewport and shelf tools that allow for artist-friendly viewport interactions. Behind the scenes, Houdini builds up the nodes and networks for you.

Houdini lets artists explore different creative paths because it is easy to branch off a new node to explore alternative solutions. Luchttann character from Ary and the Secret of Seasons by eXiin. Visual effects artists gravitate to Houdini because its procedural workflow is ideal for creating sophisticated particle and dynamic simulations. Houdini lets you make creative decisions deep into production as changes made to Houdini nodes cascade through the network to create a new and unique result.

This directability is retained throughout the creative process and can be used to make last minute decisions that would be too costly in a traditional CG pipeline. Instead of simply reacting to issues and problems, you will be able to plan ahead and visualize and refine your pipeline. Create these digital assets without writing any code then share them with other Houdini artists.

MicroCity – City Generation Toolset for Houdini

Experience unprecedented levels of flexibility and control to enhance both your creativity and productivity. Game developers face a growing demand to build huge immersive worlds populated with vast amounts of content. In order to achieve great gameplay while meeting deadlines, a procedural approach using Houdini offers a smarter way to create quality games. Designers, animators and storytellers use motion graphics to create content that stimulates audiences using powerful and compelling visuals.

Virtual and Augmented Reality creates a complete experience that takes the viewer to places they've never been before. Houdini provides a powerful set of tools that makes it easier to create and manage the content used to populate these amazing digital worlds. Houdini Core is designed for modelers, lighters, character riggers, animators and game artists. Scenes and digital assets created in Houdini FX can be opened, manipulated and rendered in Houdini Core.While it has modeling and animation toolsets, Houdini is mostly used for visual effects work.

It can create various types of pyro FX from a candle flame to a bomb explosion or water from raindrops. Not to mention, Houdini also offers a dynamic network where particles, rigid bodies, and fluids can interact with each other.

Unlike other applications, Houdini focuses on nodal procedural generation. This makes the process initially difficult but over time much more flexible. While Houdini has become a little more user-friendly in recent releases, it still has a steep learning curve. Fortunately learning Houdini will give you more work opportunities as this program is becoming the standard effects tool in most VFX pipelines. Check Out This Tutorial. You will learn the basics of node behavior such as the inputs and outputs, using the invisible and disable flag to control data flow.

Procedural Modeling

Houdini is finicky. In this tutorial you learn the fundamentals of physics simulation in Houdini, which is applicable in every scene. You also explore rigid body solvers and what settings to modify to direct them, such as collision settings. Simple enough to write, but will take time to work through these lessons and understand the concepts. The particles sell the idea that an object is disintegrating as it slowly disappears. This means you can easily turn a simple box or a complicated airship into water.

While Pyro is mostly used for practical fire effects, it can also be used for fun motion graphics pieces too. Pretty complex but it gets easier as you practice. In this free tutorial you simulate a fire, then shade and render it within Houdini using its default Mantra renderer. Well this tutorial is one such example with a focus on Houdini, but this time through a geometry behavior rather than just simple bar graphs going up and down.

This is easily corrected with a shift node. This leads you to eventually clamp and remap the data. One is to actually simulate and the other is to create it procedurally. The method can be used not only for snow, but also dust or any particle that will eventually lie down like confetti. You get to create the initial particle points using the scatter node with the relaxation turned off to lower calculations.

The tutorial teacher here gives an overview of how to simulate splines on top of each other which can resemble worms. Fortunately the author provides the source files for downloading to follow on your own. The author also shows how to export the final effect as a standalone spline and render it with Octane in Cinema4D. This leads to modifying the generation with the spawning attribute.
