Multiple Scattering in Volumes

volume-sponge-multi-scatter

Here is a test I did using the new multiple scattering in volumes available in the latest release of Arnold.

I increased the Volume Ray Depth to 6 and increased the Volume Indirect Samples to 10 to reduce the noise.

Here is a comparison when rendering with and without Volume Indirect:

Another example below, with and without multple scattering. The difference is huge!
