Blender is arguably one of the best tools for performing a wide variety graphics work, and while EEVEE and Cycles are great renderers, sometimes it is desirable to create a more specialized rendering engine for some particular task. However, getting data into these engines can sometimes be challenging. In this talk I will present some of the work I have done to connect Blender with the well known research renderer: PBRT, allowing Blender to export scenes in the native PBRT format or import existing PBRT scenes into Blender for further editing. Furthermore, this work should be easily adaptable such that you can use it you create your own importer, exporter or even renderer if you want to!
