Problem with strange shading when rendering certain objects

[leroyaliosman]

I've been getting strange results when rendering objects that are rotated off of 90 degrees. I often get strange shaded areas and gradients on these objects, particularly when there are several similar objects adjacent to one another. I've attached an image for reference.

 

I build my models in AutoCad 2016, link them into 3ds Max 2016 and render with V-ray Adv 3.30.01

 

I would appreciate any assistance figuring out how to resolve this issue.

 

Thank you.
