I have around 150,000 bgeo files that need to be processed and rendered. The workflow is set up in TOP to access and process each file as one workitem in ROPGeometry. How do I then render the geometries produced in ROPGeometry using ROPMantra? I only need one frame per geometry using the same camera.

You can use that ROP Mantra node to do that, but you'll need to put down a file SOP in your hip file to load the geo. The ROP Mantra should be configured to render that file SOP, on the Objects tab. The file path can be set to `@pdg_input`, including the backticks, in order to load the uptream bgeo file. For example, you could wire a File Pattern TOP that globs all the .bgeos into a ROP Mantra which renders them using that approach.

Thanks Taylor, it works!
