Hi there - there is a separate forum for the Poser Beta Test - pls post comments there.
Inside a dry appz is more difficult render to the same speed of a standalone..
I thought the same...for a long time...however I think that there are other issues at play, and that there render speed is the same. In the Poser plugin at the moment, the FOV is not calculating correctly, and therefore I beleive the depth of field is changing - which has a big impact of the render speed. This will be fixed in Beta04 of the Poser plugin.
The engine crashed in my I7 Extreme 12Gb when I have changed Diffuse Map Texture head

I would like to have inside a Subscattering octane native material for skin...
Yes, I found a bug with the plugin and SSS, which is fixed in Beta04.
Is there some mesh tearing on James hip in your render? (Pls post answer in the Beta test forum
