Hello Everybody
I was recently doing an automotive model in maya and rendering it in keyshot. The problem is when I import the model in keyshot the mesh is shattered importing it using the smooth mesh preview(3) in maya. I imported the model without the smooth mesh preview(1) in keyshot and fortunately the mesh is intact. i tried deleting history and freeze transformations but i couldn't get the smooth mesh preview to work in keyshot. i also tried using soft normal's but still it doesn't work. I attached a screenshot, I hope someone would help me and A HUGE THANK YOU.
Unfortunately is a known issue that "smooth preview" does not import correctly. As you found the only option is to disable the smooth preview.
The good news is that is should be fixed for KeyShot 6 together with a recent Maya version >2013
but i tried other mesh and they work just fine. here is a sample render of a logo i did and its in smooth mesh preview
It may work, as you found. But more often than not it will fail.
