Houdini - Variable Viscosity Lava - Mantra R&D

LAVA - Variable viscosity test driven by a VOPPOP custom temperature attribute on the FLIP particles. I am also using this attribute to drive the disp/Cd/emis on a mantra shader and to source density emission on the smoke solver. Lava Shader test hip scene:-

Variable foot

The foot is usually one of the areas of the body that doesn't get much attention. Stick a reverse foot rig onto everything and the foot stays rigid with a bunch of sliders in the channel editor. Well not any more. This foot rig is simple to animate but has a lot of power in its couple of controls. For more information visit

3. DIY Variable-ND filter

DIY Variable-ND filter

I'm certainly not the first to do this, but most are just picture tutorials. I thought it would be helpful to watch someone complete the process. Cheap circular polarization filters can be purchased online for as cheap as $5 each. The entire mod process takes about 10-15 minutes with the right tools. Easy and straight forward. NOTE: 1. Take care not to damage the filter when unscrewing the retaining ring. It is easy to slip and scratch the class or coating. 2. There is a reason the Singh-Ray Vari-ND filter is over $300, but for around $10 a little color shift/drop in contrast/slight vignetting (all easily corrected in post) is worth the savings in my book.

4. "Get Old" Hy Snell, 94

  • By Variable

In March of 2013, Variable was commissioned by Edelman to produce four mini-documentary films along with the print advertisements for Pfizer's cause-driven campaign; "Get Old". The purpose of the campaign is to spread positive awareness on aging by showcasing stories that break the mold of the negative pre-conceived notions surrounding the topic. As a team of ambitious young creatives, we thoroughly grasp these negative connotations so we were thrilled to put our energy into a campaign message that we truly believe in. The first of four films features Hy Snell, an energetic and awe-inspiring gentleman. When asked how he felt about aging, Hy couldn't even comprehend why we were interested in the topic. It was as if "age" didn't even exist in his world. For Hy, "age" has had nothing to do with his joy and contentment in life. His immense passion for creating artwork has kept him moving forward without looking back for over seven decades despite his ongoing battle with failing eyesight. At 94 years-old and a dwindling 5% of his eyesight remaining, Hy continues to find inspiration due to the fact that he is literally seeing things differently every day. This fact spoke volumes to us since it is relatable on so many levels. In summary, Hy truly is a living testament who proves that each road block, as tough as it may seem at the time, can provide tremendous opportunity for growth and prosperity. -- Production Company | Post Production | Creative Collective: Variable Director | Editor: Jonathan Bregel Executive Producer: Tyler Ginter Producer: Alex Friedman Production Supervisor: Paige DeMarco Production Coordinator: Alexandra Van Voorst van Beest Cinematographer | Photographer | Colorist: Khalid Mohtaseb Art Director: Joseph Sciacca 1st AC | DIT : Dan Stewart Sound Mixer: Anthony Viera Assistant Editors: Dan Stewart, Jeff Levine Motion Graphics: Maha Mohtaseb Creative Assistants: Ashley Horton, Michelle Brooks, Dotsie Bregel Client: Pfizer Agency: Edelman Creative Development & Casting: Edelman & Variable Executive Creative Director: Jimmie Stone Executive Producer: TJ Sponzo Copy Supervisor: Kristen Dietrich Original Score: Keith Kenniff Unseen Music, 2013 | Sound Mix & Design: Brooklyn Post Studio -- [email protected]

Houdini FLIP R&D - variable viscosity lava simulation

Inspired by other Houdini and Realflow artists lava R&D, particularly Graham Matthew Collier's impressive work. I'm new to Houdini and am still wrapping my head around much of the functionality, so there is much to be improved here. I'd like to add a pyro sim for smoke, and proper UV mapping so that I can get better displacement detail. Currently using a variety of custom point attributes to drive the various shader properties and variable viscosity mapping, which requires a pretty low particle separation value and results in slow sim times. The render quality also leaves much to be desired! The variable viscosity created by remapping a diffusing temperature attribute that gets set in the source SOP. This results in more variation in the cooling time, as thicker masses of lava cool more slowly. Thanks for watching, suggestions welcome!

A Reflection

This mini-doc shares the story of Władysław Tomczyk, a gentleman we unexpectedly met in Katowice, Poland after wrapping a month-long commercial project throughout Europe. His hopeful message of creating life-work by honing one's natural ability is one we value to the core at Variable. What began as an insightful conversation, motivated us to extend our trip by 3 days so we could capture this inspiring man's life. With no pre-developed story or shot-list, we let our curiosity & conversations with Wladyslaw guide the film. As a result, his outlook on life furthered our belief that contentment through self-acceptance trumps societal approval. Free your mind. -- Production Company: Variable Director: Variable Cinematographers: Jonathan Bregel & Khalid Mohtaseb Producer: Tyler Ginter Art Director: Joseph Sciacca Local Coordinator & Translator: Piotr Labercheck Editorial & Color Grade: Salomon Ligthelm - Original Score & Sound Design: Tony Anderson - Post Story Producer: Susan Modaress Polish Translators: Sophia Whitman & Arkadiusz Lesniak -- [email protected]

9. Variable FK Autorigger

Variable FK Autorigger

download: If you create something worth seeing with it show to me, I am curious :D This is a quick demonstration of my autorigger I wrote for the variable forward kinematic concept presented by Jeff Brodsky in this video: This is my first maya scripting project of this size but since it would require a lot of manual steps to set this up all by hand I decided to write it as an autorigger right the beginning plus I thought it could be fun. It is the first time I used pymel and made an UI for a maya script so the code is probably pretty messy but it reliably does what it's suppossed to do. Variable FK is a bit more dynamic than normal FK controls because it adds the feature to move the controls along their jointchain while the influence of a control on a joint is determined by the distance between them. The moving along the joints part works similar to a ribbon rig and the distance-influence calculation is achieved with utility nodes. This kind of rig works well for: - tentacles - tails - plants (mainly ferns) - belts - adventure time style limbs - elephant trunks and probably much more. feel free to experiment, feedback appreciated

Featuring Sid, the invisible displaced sphere! ;) Viscosity based on point age, remapped with a ramp in a POP VOP. Rendered with Mantra PBR. Hardening speed is exaggerated to be sure, was trying to preserve all the nice folds that form initially.

Harrison Metal – Fixed & Variable Costs

Another awesome Harrison Metal lecture that I got to animate at Dress Code. This one's packed with fun stuff: liquids, horses, bullet time, all in the name of illuminating how to deal with the different natures of various costs for your business. Shout out to Evan Anthony for that cloner-object expressions code, that he whipped up in all of 45 seconds, for the falling cup pyramid sequence. I'm still amazed.

Houdini FLIP R&D - V2 Variable Viscosity Wax Pour - updated shader and meshing

Same sim as previous, just playing around with the shader a bit more. Still needs some work on the transition from refractive to solid, it's a bit harsh currently. Just one camera angle, with a replay at 1/2 speed (dodgy AE pixel motion interpolation...) I also switched to using the "Particle Fluid Surface" node instead of VDB for the meshing. Quality is comparable, and it's much simpler to set up with no extra cleanup/smoothing nodes needed.
