I'm trying to batch render things with POV-Ray (several thousand things at that, trees made from Arbaro, since Arbaro lacks an automation feature) and the GUI is the biggest problem I'm having right now - I can't get it to stop coming up through command line execution. In the PROCESSINFO structure, I have the "SW_HIDE" flag set with (the appropriate flag set in the dwflags field to use it). In the CreateProcess function, I have the "CREATE_NO_WINDOW" flag set. Even with both of these, the GUI still comes up and I can't have it coming up every time. Is there a way to stop the GUI from coming up at all? Do I have to get an older version of POV-Ray just to use pure command line execution for a render without the GUI coming up? If so, what's the newest version of POV-Ray that I can get that has this pure command line execution without the GUI coming up? I've got everything else working now but the GUI is getting in the way. I only just want this to run in the background so I can, for example, eat, take a shower, or work on other things while this is going on. The unwanted GUI is the only thing left to deal with at the moment.
