-y (global) Overwrite output files without asking.

that didn't work unfortunately.
added hou.parm('/obj/EXPORTS/camera_to_points1/renderme').pressButton() as a pre-render script
but still when the TOP cooks the workitems the output images are all the same, from the same frame.

Your script is in the pre-render parameter, which runs once per render on the first frame of the render. It sounds like you want to have it in the pre-frame script instead, which runs once a frame.


Regarding the the reload parameter option on the ROP Fetch itself, the button specified in that parameter should be pushed every frame even when using a batch.

The script parameters on the ROP Geometry Output are on the underlying Geometry ROP itself, and are just promoted onto the TOP node. If you want to run a pre/post script with a ROP Fetch you'll need to put them in the pre/post script field(s) of your ROP.
