  1. Hello I'm trying to make a little script that would check which frame was the last one rendered and then would continue the rendering process if necessary. It's a Windows machine The easiest way I could think of doing it was simply using the subprocess module to call the hrender script with the proper arguments, but I having some trouble The relevant code is def main(): last_known_frame = get_last_frame(RENDER_DIR) if last_known_frame is not None: hrender_command = "hrender -e -f {} {} -d {} {}.hip".format(last_known_frame, END_FRAME, OUTPUT_DRIVER, PROJECT_NAME) os.chdir("V:\Programs\Side Effects Software\Houdini 15.5.607\\bin") subprocess.call([hrender_command], shell=True) However, I get a "hrender -e -f... is not a recognized as an internet command..." I tried using subprocess.call(["hrender", hrender_command], shell=True), with the proper path to the HIP file, but then it calls it like they were two different arguments, which isn't the case So three questions Is what I'm doing possible? What am I doing wrong? Is there a better way? Regarding the second question, I superficially searched how to use HOM on a generic script but apparently you need to assign PATH variables and such on Windows, it looks like a mess I would prefer to avoid if possible Thank you
