Houdini 12.5

Fri 15th Mar 2013 | News

This new version of Houdini includes integrated OpenVDB sparse volumes with new Cloud and Ocean FX Tools.


Side Effects Software has announced the immediate release of Houdini 12.5 offering a wealth of new and enhanced features including Cloud FX, Ocean FX, OpenVDB volume sculpting tools and an optimized lighting and rendering pipeline with built­-in support for delayed­ load Alembic primitives.


The new Cloud FX tools offer an artist­-friendly way of building, sculpting and rendering cloud formations. This workflow utilizes sparse volume sculpting tools created as part of the OpenVDB [] open source initiative. The integration of these tools is the result of a direct collaboration between DreamWorks Animation and Side Effects Software.


“OpenVDB 1.0 is now fully integrated into Houdini,” says Cristin Barghiel, Director of Product Development at Side Effects Software. “Side Effects has used it to build high­ level Cloud FX tools for artists based on a variety of low­level volume sculpting tools provided by DreamWorks Animation with OpenVDB.”



Houdini 12.5 includes an Ocean FX Wave tool which deforms geometry into animated oceanscapes using volumes. You can visualize the results in the viewport and either render the geometry as is or export an animated texture to use as a displacement map. The Ocean FX Wave Tank tool goes even further and lets you generate a FLIP fluid simulation derived from an animated ocean surface. For even more realism, a unified Whitewater solver is available to create spray, foam and churn based on the underlying FLIP fluid sim. A new Mist tool can then be used to further enhance the whitewater effects.


Igor Zanic and Thomas Hullin are two VFX Artists who beta tested Houdini 12.5 and its FLIP fluid tools. “Houdini 12.5 has the best fluid solver on the market. It is fast and reliable from large scale liquids to small viscous stuff,” says Thomas. “With the power of Houdini’s node­-based procedural workflow you can really optimize your simulation. And the integration of Rigid Body Dynamics and FLIP fluids is extremely powerful,” says Igor.


The lighting and rendering pipeline in Houdini 12.5 has been significantly enhanced with relighting options and optimizations in IPR [Interactive Photorealistic Rendering]. Primitive support for file types such as Alembic resulting in much lighter data passing to either the viewport or the Mantra renderer. These enhancements make Houdini much more robust when working with huge data sets and demonstrates one of the key reasons studios are taking a closer look at Houdini’s Mantra renderer as their 'go­-to' renderer.
