Once you are happy with how the cloud is looking, you are ready for final frame rendering.
Replace the VDB file wdas_cloud_sixteenth.vdb with wdas_cloud.vdb. Bear in mind that this is the full resolution VDB file and so will take longer to render.

'wdas_cloud_sixteenth.vdb'. Rollover image to view 'wdas_cloud.vdb'
Once you are happy with the lighting (and shading) increase the number of Volume Samples for the Skydome light to around 5 or 6.
Increase Camera (AA) to around 5.
Under Sampling in the render settings, increase Volume Indirect to around 3. This will help to remove noise from the indirectly lit areas of the volume.

Finally, render the scene. That concludes this tutorial on how to render a VDB cloud data set.
Tip
Once you have completed this tutorial, remember to take your head out of the cloud!
