Volume Rendering
Render volumes are even more realistic in raytracing with multi-scattering for rendering volumes. Results are sped up due to improved volume traversal optimization, which is automatically used.
Video captions: If you are working with volumes, you will be happy to hear, that now we added a new calculation method called multi-scattering. This provides a more physically accurate result, as it considers the scattering of light and color within the volume.
Multi-Scattering Support for Volumes in Raytracing
When multi-scattering is enabled, traversal optimization is automatically used. For a ray entering a volume, a search for the entry and exit point is done. For each scatter event, a search for the new exit point is done, which significantly speeds up multi-scattering.
With VRED 2025.1, there are now two approaches for rendering volumes, ray-marching or multi-scattering. Multi-scattering provides a more physically accurate result, as it takes into account the scattering of light and color within the volume.

However, it is more computationally intensive and requires more samples to converge to achieve a noise-free result. Therefore, it is currently only available for Raytracing.
