Hi there

Here are my settings in 3DS MAX and they works without the single issue

Export from Poser

And simple render in Corona Render (Corona Alpha v6 ),on my spec this render took me just 150 passes/10 mins,there is visible noise which can be cleared after I would say after 50-100 more passes

In 3DS MAX don't use Poser preset,with this preset I've few problems in past

Hope this helps

Thanks,Jura
