I know, I did that last night and is why I’m asking here. And more recent versions of Arnold in maya 2020 Under the autobump tick box there are options. I was looking for the new documents that explain them in detail. I am aware of what autobump does. I knew someone would come with that response and is why I put examples of what I was looking for such as diffuse transmission.
"Autobump is visible to camera rays only by default. The visibility parameters let you make Autobump visible to other rays (eg Specular and Transmission) however that can increase render times."
Thank you, I was just curious and before bed last night I did a google search and was unable to find where these are explained in the docs. So, I thought to ask for the link to them for reference. I know if you enable them they render. I'm simply asking for a link to that portion of the docs. It doesn't have to be any more complicated then that.
