In case you haven’t seen it already, my presentation on MOPs at Houdini Hive Worldwide has been online for about a month now. Here’s the presentation: I’d forgotten to upload the example files I built during the presentation. They’ll be included in the examples directory in the next Experimental release Read more…
This is a sort of sequel to the previous post I made about handling the Houdini.env file, and about configuring environments in general. Houdini 17.5 introduced the concept of “packages”, which are little JSON files (JSON meaning JavaScript Object Notation, filling a similar role as XML or YAML) that define Read more…
I’ve been putting off working in ACES for years now, because almost every explanation of the system I’ve tried to read online has been either extraordinarily technical and long-winded, or read like a sales pitch with no useful information about implementation. It takes a certain amount of training and understanding Read more…
I continually run into confusion from Houdini users about how the Houdini.env is supposed to work, what the syntax is supposed to be, or even what it does in the first place. It’s easy if you’ve been trapped in pipeline land (like me) to think that environment configuration is even Read more…
Another year, another very very short side project. This was meant to be both an exploration of Vellum (and an attempt to see if I could force Vellum to work in 2D), and a neat little intro video for a new demo reel. This project is considerably less complicated than Read more…
SideFX Software was generous enough to ship me out to the Netherlands last week to meet my partner-in-MOPs, the inimitable Moritz Schwind, and present together a little slide show about motion graphics, Houdini, and prison hooch at End User Event 2019! The technical stuff about MOPs starts about halfway through Read more…
Here’s a rare Maya post in 2019! I hate Maya, but sometimes it’s hard to avoid. One of the most irritating things about writing scripts for Maya is that the Python commands are totally un-Pythonic… meaning, there’s no sense of “objects” that have intrinsic properties and functions (or in Python Read more…
I meant to write a post about this a long while ago, but couldn’t be arsed to do it, apparently. Sorry! Something that artists take for granted in render engines like VRay and Arnold is the ability to reflect and refract AOVs / render elements / render passes, depending on Read more…
Update: Imre Tuske from Weta pointed out that there’s a simpler method… it turns out that you can force expressions to evaluate inside a Wrangle by wrapping them up in backticks. So if you have a channel called “do_vexpressions” to enable or disable VEXpressions, and another channel called “vexpression” that Read more…
After months of work, the MOPs toolkit for Houdini is finally open to the public! MOPs is a suite of SOP tools to help with common motion graphics tasks in Houdini. The workflow and interface should seem familiar to users of other motion graphics software packages, but it’s using Houdini-friendly Read more…
