Stormz covers create proxies in Karma and Solaris in Houdini 19.5, using two methods.
Stormz has been working with some of the newer open-source goodies in Side FX Houdini, working with Karma, USD, and Solaris. His latest shows how you can knock down polygon counts using proxy geometry when working with Houdini’s Karma renderer and Solaris.
“We know from the Layout LOP that we can set our proxy geometry for assets, but how can that be achieved?”
The tutorial also covers a secondary method of managing polygon count in the viewport.
