Cloud FX Tools

New Cloud sculpting and rendering toolset available on a dedicated shelf:

    Cloud Rig - This tool creates a cloud network using the Cloud, Cloud Noise and Cloud Light nodes in combination along with a Sunlight and Skylight to create a complete cloud setup.
    Cloud - This tool converts geometry into a cloud volume and a gives you control over the shape and density of the volume. Secondary Shapes can be added to give your volume a puffier look.
    Cloud Noise - This tool adds a noise pattern to the volume to create a more distinct cloud-like shape.
    Cloud Light - This tool computes a light field to support the rendering of the volume. This approximates the scattering of light in a cloud to create a more efficient rendering.
    These Cloud tools are built using the new OpenVDB Sparse Volume tools.

Ocean FX Tools

New Ocean FX tools make it easier to integrate ocean surfaces into your VFX work:

    Ocean Waves - This tool uses volumes to deform geometry to create an animated ocean surface. You can visualize the results in the viewport then export a displacement texture to use at render time. This tool is on the Deform shelf.
    Wave Tank - This tool creates a FLIP fluid simulation with whitewater from an underlying ocean surface. This tool is on the Particle Fluids shelf.
    WhiteWater - New, unified whitewater solver creates spray, foam and churn based on an underlying FLIP fluid sim. This tool is on the Particle Fluids shelf.
    Mist - This tool emits mist particles into a smoke simulation one-way based on an underlying FLIP fluid sim. This tool is on the Particle Fluids shelf.
    New Ocean Spectrum and Ocean Evaluate geometry nodes used to generate ocean surface, volume and point outputs.

Sparse Volumes

    Native support for OpenVDB primitives. OpenVDB is an open source C++ library comprising a novel hierarchical data structure and a suite of tools for the efficient storage and manipulation of sparse volumetric data and is developed and maintained by DreamWorks Animation Visit openvdb.org for more information.
    Over a dozen VDB geometry nodes to create, manipulate and convert VDB volumes: Convert, Activate, Advect Points, Analysis, Combine, Fracture, From Particles, From Polygons, Renormalize SDF, Resample, Reshape SDF, Smooth, Smooth SDF, Vector Merge, Vector Split, Visualize Tree.
    Native viewport and Mantra support for VDB primitives.
    VDB volumes in Mantra have support for vector VEX attributes.
    SOP support for doing forward and inverse Fast Fourier transforms on 2D and 3D volumes: Volume FFT SOP.


    Accurate handling of droplet particles.
    Faster and more scalable FLIP fluid simulations.
    Fully OpenCL-accelerated Gas simulation pipeline in Pyro.
    OpenCL DOP for custom acceleration of simulation performance.
    The FLIP solver can now handle animated density and viscosity as well as animated timescales.
    FLIP fluids now use OpenVDB to generate the fluid surface and use uniform volumes for rendering.


    New constraint types: Slider and Cone Axis which is useful for rag-doll simulation.
    Ability to handle concave geometry.
    Support for Cylinder geometry types.
    Support for interpenetrating or “bad” geometry.
    More reliable behaviour under complex scenarios.
    Ability to visualize objects that have been put to sleep by the Bullet solver.
    Ability to toggle collision detection between objects.
    Ability to handle an animated centre of mass.
    General performance improvements.


    Optimized performance and collision support.
    Support for panel workflows.
    Support for per-vertex multiplier attributes, in addition to per-point attributes, offering more freedom in controlling the behavior of parts of the cloth.
    UV support for triangles and cloth -- the UV coordinates represent the threading of the material and make the solver independent of the underlying topology.
    Improved force model, with more independence between stretch, shear and bend.
    Visualization of velocity and surface collision thickness which takes into account the point thickness attribute.
    Cloth shear stiffness and damping are now independent of their stretch equivalents.

Hair and Fur

    New, surface-based collision - more accurate than the existing volume-based collision method.

Lighting and Rendering


    Volumetric geometry is now supported as a geometry type by the Geometry area light: Volume Light - this tool sets up a Geometry area light using a volumetric point cloud. This light type can be applied to volume such as a fire simulation to realistically illuminate the shot using the flame volume. Removed point cloud support from the Pyro FX shader now that we have a volume light with point cloud support. Improved the default settings for the Sky Light to create a more natural look and sun angle.

IPR View

    IPR relighting buffer for faster feedback when tweaking material values.
    IPR shared memory for volume geometry updates. When using IPR, Geometry is now passed directly to Mantra bypassing the IFD file. New option to force shadows to be ray-traced, rather than shadow-mapped, in IPR . Realtime Render Tile feedback.

Primitive Support

    First-class support for the new VDB, Alembic and Polysoup primitives.
    Alembic Delayed Load Primitives are deferred rendered into the viewport and supported by Alembic procedural in Mantra at render time. A great way of working with and rendering large scenes without loading them directly into Houdini. Ability to query properties of materials and lights from procedurals. New Point Replicator procedural. This procedural is used by the new white water tools and is available as a geometry node to allow for reviewing in the viewport.

Rendering Volumes

    More accurate volumetric velocity motion blur with ray tracing.
    Volume quality channel parameter for empty space culling.

Deep Raster Support

    Per-light exports can now be used to produce deep raster planes for export variables defined by light shaders.

Optimizations and Enhancements

    New ray-tracing accelerator.
    Many multi-threading enhancements.
    Threaded displacements for faster performance.
    Sample-based edge coving.
    Much better ray tracing performance with transparency (eg fur).
    Ability to query properties of materials and lights from procedurals.
    Changed the behaviour of lights in Mantra: the composition of the surface and light shader is now used for shading of area.
    lights instead of choosing one or the other based on a render property.
    Most point cloud formats used by Mantra (SSS point clouds and photon maps) now use Cd for irradiance rather than E. SSS point clouds also store a positional P channel.
    The obsolete "Environment (*)" light type has been removed from the HLight OBJ. One should use the Environment light from now on.
    A new render property lets the user scale the point sizes at render time.

General Enhancements

    Multi-line parameter allows typing a “snippet” of VFL code (related to Snippet VOP).
    Much faster navigation of node networks.
    Some node tiles (eg File OPs and Constant VOPs) have labels that are driven by their parameter values for better clarity of what the node represents.
