Hello Melvin

Sorry - I have no idea what do you mean and how I can help you.
Perhaps add some marks on your render, so we can see what's wrong?!

Cheers
Marco

If I understand correctly, it looks like this is a tessellation issue. Try increasing the tessellation value upon import. You can also try right-clicking on the part and selecting 'edit geometry', then try the edit normals option. Next, click 'calculate normals', then accept the changes and see if it looks better.

The calculate normals trick works most of the time for my imported models. I wish there was a quick and easy way to do that globally instead of part by part, maybe be able to do the operation to a group. That would be fantastic.

Me too. It should be able to be done upon import using the import options if I'm not mistaken.

KeyShot 5 does not have the ability to edit geometry, this feature is in KeyShot 6/7.
