OMG a Batch Render option would be heaven. Soooooo tired of being trapped at my computer all day rendering already built scenes. Heck, I'll donate money to your PayPal account to get this feature implemented. I'll keep my fingers crossed.
There are some complications for implementing this.
1) If you started a batch render, you wouldn't be able to use Poser for anything else
2) You could only render one image from each Poser pz3 file during the batch render (ie. you couldn't render an animation)
So it would really only be good for working on 5 scenes during the day, then letting them run overnight. And if something goes wrong, the batch rendering would stop.
There are some options you can do TODAY....
1) Purchase additional video cards. If you get another (690 in your case) card, you effectively halve the time to do each render (assuming you have only one card at the moment). Obviously the economics behind this will be different for each user.
2) Setup a batch render by having a scene to render at each animation frame. So your first frame will be Poser frame 1. Then setup your next scene at frame 2, etc. All frames will need the same figures/props etc, so you might need to hide some things not used in some frames off to the side out of the camera view. Then simply render the animation.
3) Run both PP2012 and PP2014 at the same time. Load a pz3 in PP2014 and start rendering, then work on setting up the next scene on PP2012. Make sure you don't run the plugin on both PP2012 and PP2014, since you run the risk of running out of VRAM.
