Just bought the plugin and its fantastic, thanks JimStar! One thing I have noticed though is the absence of subsampling/render priority options and there is no gradient texture node. Is there any ETA on these?

I think '/Developer/GPU Computing' applies only for the GPU Computing SDK which I assume you would not have installed so ignore that part.

You can uninstall your current version by
