Here are my test renders,2 of them are rendered in Poser Pro and one is rendered in renderer which I'm beta testing

First render is rendered in Poser Pro with IDL,GC ON,render settings are not high,due this you can see light leaks,I've altered walls on all of them as I don't like the grey walls and I've used single light as Infinite light set at 85% with raytrace shadows set 6.0

In this particular I've used 2 Infinite lights,first one is just for shadows set at 75% and second one just for brightening up set at 25%,render settings always has been same

Last render has been rendered in beta render SW which I'm testing and render took around 15mins in CPU mode only and in GPU mode(OpenCL mode on R9 290) this particular scene took under 5mins and settings has been pretty much average and I wouldn't say they're been high for this test(as you can see around the ear there is light leak),for lighting I've used only mesh light and dome and for floor its done by plugin only texture I've used

For rendering in Poser Pro using only dome light not sure if I would use,you will need extra source of light,that's my view on this

Hope this helps

Thanks,Jura
