Rohan Dalvi is from India but he doesn’t work for SideFX - he’s just a super nice guy who makes great Houdini tutorials, SideFX is located in Toronto Canada and an office in Santa Monica.
with regard to procedural modeling - don’t get the wrong impression that modeling in Houdini must be procedural - you can model just like you would in any other application, but you’ll find lots of opportunities to use proceduralism to your advantage. The last couple of versions of Houdini have brought a few new tools to modeling and updated version of some existing tools (and more to come). What you might not find at the moment are some of the UX/workflow features found in applications better known for modeilng. The Houdini Apprentice version is fully featured (with a couple of minor limitations) and it’s free - I’d suggest giving it a try.
