This page provides information about the OpenVDB texture in V-Ray for Blender.
Overview
The OpenVDB texture node in V-Ray for Blender allows importing and adjusting textures from the OpenVDB library.

Node Input Sockets
This section describes the input sockets of the node. Some sockets have dedicated parameters, which are further described below, and some sockets are just inputs.
Mapping – This slot allows you to connect a Mapping node (UVW Mapping, UWV Randomizer) to adjust the UWVs of the texture.
Vector Mult (input socket) – Allows a color node to specify the Vector Mult parameter.
Mapped
File – Source path to the OpenVDB file.
Render Grid – The name of the OpenVDB grid to render.
Velocity Grid – The name of the velocity grid used for motion blur.
Delay Load – When enabled, it delays the OpenVDB voxels until requested.
Interpolation – Set the grid interpolation sampler:
Linear
Quadratic
None
Use 3d Mapping – Enables or disables 3D mapping for the procedural texture. Note that his mode is not supported yet by the Hybrid (CUDA) engine.
Float Mult – Texture multiplier for the float data.
Vector Mult – Texture multiplier for the vector data.
