Key Features

GPU Rendering

Fancy Bullets
typecircle
  • V-Ray for Houdini comes bundled with the same GPU rendering improvements implemented in the other V-Ray Next DCC integrations.

Volume Rendering 

Fancy Bullets
typecircle
  • Support for VDB rendering through the Volume Grid Cache SOP and the Volume Grid Shader VOP.
  • Support for direct rendering of volumetrics without the process of loading the files through a Volume Grid Cache SOP is coming in the future. A major advantage of V-Ray vs competitive products is the fast computation of volumetric lighting, ie. fire illuminating the smoke and fire illuminating the scene.

VRScene Rendering

Fancy Bullets
typecircle

  • Instancing of VRScenes with custom transformations and orientation is fully supported, allowing the user to easily transfer assets in a V-Ray based pipeline.

  • Custom overrides on the imported VRScene are fully supported. Geometry in the VRScene is represented as Primitive Groups, allowing you to override the material assignments on a per-object basis.

Alembic support

Fancy Bullets
typecircle
  • Тargeting of individual objects in the packed alembic hierarchy for material assignment is fully supported. Transformations, copying, instancing, etc. are supported.

Hair & Fur

Fancy Bullets
typecircle
  • Rendering of Houdini hair generated at the SOP level is fully supported. V-Ray for Houdini comes with the new Hair 4 shader.

Particles

Fancy Bullets
typecircle
  • Driving the shader parameters through custom attributes on a per-point basis is supported.

Packed Primitives

Fancy Bullets
typecircle
  • Тargeting of primitives in the packed object hierarchy for material assignment is fully supported. 
  • Rendering of Packed Fragments and Agents for Rigid Body and Crowd simulations is supported.

Material Stylesheets

Fancy Bullets
typecircle
  • Full support for material overrides based on groups, bundles, attributes, etc.

Instancing

Fancy Bullets
typecircle
  • Copying of Packed Geometry, Instancer and “instancepath” attribute works with all supported object types, including Volumes.
  • Instancing of lights is supported, with options for per-instance overrides of the light parameters.
