OpenVDB Support

Brutal Engine natively supports OpenVDB for heterogeneous volumes such as clouds, smoke, and fire.

Load any standard .vdb file via the Volume node in Maya. The engine supports:

• Density channel mapping.
• Temperature channel for blackbody emission.
• Velocity grids for motion blur (future support).

Scattering

Control the look of your volume with Scatter Anisotropy (using Henyey-Greenstein phase function). Positive values create forward scattering (clouds), while negative values create back-scattering.
