Maya: A Static and Impressive VDB Explosion
openVDB is a format which describes objects with no hard shell, smoke, clouds, fire. In Maya these things are being handled by volume materials.
With the Arnold Volume shader alone you can achieve amazing effects. VDB shortens the path to a good result dramatically. I use only four steps in order to get this explosion.vdb to look amazing.
The tutorial is only 10 minutes long, so I don’t animate the explosion, I just render it in its static state, described by the VDB file. To follow along, search the web or your local hard drive for .vdb files, there are tons of them out there on the internet.
