In this video I demonstrate how to convert a folder of .OBJ files into .RS files which can be rendered by the Redshift system. I demo a script which scans a folder looking for .OBJ files and creates a geometry node in the Houdini scene which references the item in the folder. A naming system is put in place which allows logical referencing of generated proxy files via simple VEX code. This system demonstrates how you can use one file type, .bgeo.sc, to drive the viewport display and another file type, .rs, for rendering.
