render details lost

I quite baffeled as to why I'm losing so much detail in highly detailed renders. I've attatched an image that was rendered with mental ray with a point light and final gathering. The loss of information on the steps has nothing to do with image compression, it's inherent in the render. Any ideas?

could it have anything to do with the anti-aliasing (just throwing ideas up).

have you tried upping the number of FG rays/ upping the accurancy of the FG?

up the amount of Finalgather / GI rays... that should up the clarity, otherwise, check antialiasing settings, and maybe some of the FG of GI accuracy settings if your app has them.

(lol, basically what was said before....)

I don't know if upping the number of rays will do much more than make your renders take longer. At a guess I'd say you need to adjust the FG min/max radius settings, as I understand it if the min setting is larger than the smallest detail you want captured, it won't show those details very well. Try finding the size (height or depth, whichever is smaller) of one of the steps, set the min radius to that and see how it looks. It should at least get you a bit closer to an acceptable result, and you can tweak from there. Tweaky, tweaky, tweaky. And so on.

This is a very rough rule of thumb (so don't expect miracles), but it's helped me before

Thanks amigos

>>waboflex - thats great to know, I was wondering about the min/max radius and just neglected to look it up. Anyhoo, it usually makes more sense to me when somebody else says it as to opposed to manual jargon.
