This Houdini n9 software tutorial covers a very simple lighting and rendering scene to show the basic workflow for generating a PBR render. We use a digital asset to quickly establish a group of geometry to light. In the lesson we also add an area map so that we can extract the lighting information from it. There are two .rat files to experiment with, the seashadow.rat file simply provides a pattern. The st.peters_cross.rat is an HDRI image from the Debevec site. Watch and learn how to set up basic Physical Based Renderer (PBR) lighting in Houdini 9.
