The rendering is really noisy sory I can't be more specific :-)
24 sec of rendering.
The only way I found was checking the " use Color Channel for Node material" the rendering becomes faster but not the same result. So how can I get rid of that noise, without hours of rendering. It's a basic standard render without any modyfication.
Not sure of that solution. By the way because your are the Node master :-), could you give me some tips about my other question about HDRI and AO couldn't find anything neither in the help neither in your training. Maybe I'm doing the things the wrong way.
