I haven't used base Houdini in years, mostly working in Maya while at DreamWorks TV. Getting back into it and seeing what has changed in the ~5 years I've been 'away' is a lot of fun...even if I manage to break textures along the way.
My goal here was to look at the scene at provided, remove the lights, and then re-create the setup to the best of my ability. I then brought a rendered still into Nuke and gave myself 5 minutes to 'play'.
