In tandem with our ongoing Learning Houdini journals, we are sharing one of Rohan Dalvi's free tutorials. In this tutorial, Rohan talks about the difference working "procedurally" makes in the 3D creation workflow. If you don't know about Houdini and its procedural-based operations, check their website page on the "Procedural Workflow" first.
