A Few Words with Johnny Farmfield

Sometimes you come across Houdini setups that just blow your mind. I still remember seeing this setup of a baseball and thinking how in the world did they figure out how to accomplish this? And who is this individual who posses such magic? Well, the person in question is Houdini TD Johan Gardfeldt or as many may know him online as Johnny Farmfield. It also turns out it’s just good old fashion problem solving. A concept that comes up again and again in my few words with Mr. Johan Gardfeldt. Some great things I learned about Johan. One is that […]

Redo Node Operations in Houdini Revisited

Well, this is embarrassing. Another one of those, staring you right in the face type of things. Or when you have a hammer, you want to nail stuff. Remember our last #QuickTip and how we did this little process to reselect or redo the operation on an node? Well, that is still valid for certain nodes, however there is a better way to achieve the same. Waaaay better. The Little Arrow You may have thought that redoing an operation on a node was rather cumbersome. Agree, not the most straight forward way of doing it. Have a look at the following […]

Redo Node Operations in Houdini

So here is something you most likely encounter at some point. We know we can go back and change the parameters of nodes in Houdini. That’s the beauty of its procedural workflow. However, what happens when you’re working with groups or a node that is affecting a certain set of primitives or points and you decide you need to modify the selection? In other words, you want to subtract or add to the group’s set for example. In this #QuickTip we will see how to redo node operations in Houdini.   The Problem Let’s say you are working on some […]

Different Ways to Randomize Scale in Houdini

Different Ways to Randomize Scale in Houdini

So when I first started learning Houdini I would jump in and try to recreate simple scenes that I would often do in Cinema 4D. One of them was to randomize uniform scale on a bunch of geometry. Simple enough. I would start to create the scene and then realize I had no clue how to do it. WTF! It can’t be that hard to randomize scale in Houdini.   Well, it isn’t. It’s actually really easy. I just didn’t know about one important attribute known as @pscale. I bet if you’re just starting out, you have fallen victim to […]

Creating Spare Parameters in a Python SOP

The other day I was watching Just One of the Guys and suddenly I thought how would you go about creating spare parameters in a Python Sop in Houdini. I mean, we know that in our trusty VEX Wrangles, we write a line of code, click on that little thingamajig and suddenly we have our custom parameter. However, I don’t remember seeing one of those in a Python SOP. Hmmm… Anyways, today I’ll go exactly over that!  We will be creating spare parameters in a Python SOP and connect the Python code to the parameter. A little different than in […]

Quickly Jump to VOP Inputs and Outputs in Houdini

These days I find myself in Wrangles more than I do in VOPs. I also prefer seeing the code as opposed to using the visual “programming” in applications such as Houdini or Unreal Engine. However, sometimes it’s just easier to wire up some nodes or maybe you’ve received a file constructed with VOPs. Hopefully, that person was kind enough to label and name their operators. If not, it’s like diving into an unknown sea of nodes. If that’s the case, this #QuickTip will help you out and show you how to quickly Jump to VOP Inputs and Outputs in Houdini. […]

Automatically Create Redshift ROPs When Starting Houdini

Automatically Create Redshift ROPs When Starting Houdini

Remember the 123 and 456 Python scripts that we talked about extensively here, here and here. Sure you do. Those scripts are quite handy since you can customize Houdini when starting up or when opening a scene. I make great use of them. I know when starting up Houdini I want a camera and a Mantra node so I have the scripts automatically create them for me with some default parameters already set up. However, what if you are one of the cool kids using these new fancy render engines such as Octane, Arnold or Redshift? What if you want […]

Creating Attributes with Python in Houdini

A few questions have rolled in regarding the Mograph Multishader #QuickTip. Remember we were grabbing a bunch of images from a folder to randomly texture some geometry. One question in particular was how to have Houdini automatically determine the number of images in a folder? This would require we query the folder somehow and store the data in some variable or attribute. What better way to do this than with our friendly neighborhood programming language, Python. In this #QuickTip, we will be creating attributes with Python in Houdini to help us determine the number of objects in a folder and […]

Mograph Multishader Setup in Houdini Revisited

Mistakes. Mistakes are great. They help you learn and improve. As they say, if you are not failing, you are not progressing or something to that effect. In our Mograph Multishader Setup in Houdini #QuickTip, we looked at how to texture planes with random images from a folder similar to Cinema 4D’s Multishader. We are back to look at some of the things I goofed up on. Are you ready? Mistake One If you recall, our setup was rather simple. A network for our frame and a network copying our frame to a bunch of scattered points. We wrote some […]

Mograph Multishader Setup in Houdini

So if you run in the Mograph circles you most likely have come across the infamous random image to plane deal. You know the one. The one where you take a folder full of images and map them to individual planes. I know I’ve had my share of it. Sure enough, I was asked to do it again recently. Normally, I would reach for Cinema 4D and quickly set it up. However, I wanted to try it in Houdini since I figured this would be a piece of cake. There are probably multiple way of dealing with this setup in […]

A Few Words with James Owen

Several years back I developed a plugin for Cinema 4D called Hangover. Not only did it make me a few bucks, more importantly it was a great learning experience since it really pushed me out of my comfort zone with Python. I owe this to one person’s encouragement. That fellow is James Owen or also known as Chiny or as I had met him, Hypoly. I’m sure you have seen some of his work online. Maybe a few Vimeo Staff Picks or are even using some of his tools. James is an award winning designer and director within the motion graphics […]
