Experiencing rendering problems in Inventor 2016

[pmanagan]

I am using inventor 2016 and trying to render a model. It looks terrible after rendering. I was using 2014 prior and did not have this issue. Is there a new setting that I may be missing? Thanks so much!

Maybe you could upload an image of what you're getting for results?
Maybe an explanation on how you're rendering the file, your step by step process?
Other information to explain what you do and how you do it?

That may get you better help, and possibly more answers.

Thank you for your reply. Attached are 3 images (stair image 1,2 and 3 after rendering in 2016. Also attached is a rendering I did in Inventor 2014 doing it the same way. I go into inventor studio and render image. I'm wondering if this is just a setting in 2016?

The rendering engine was changed in the past couple of releases, so yes and no to the question of "is this just a setting". Images are rendered in "passes", with each pass refining the results of the last. When not enough passes are done the image looks grainy as yours do. High quality images (reflective materials, textures, shadows, etc.) require many more passes than low-quality (basic lighting, simple shadows, no reflections, and so on). I'm not intimately familiar with the Inventor render settings, but there should be some sort of "quality" control to either directly set the number of passes or a limit on how much time it spends.
