Render option for fast-and-jagged vs slow-and-smooth?

Seems to me we used to have access to a render option that provided a choice between fast-and-jagged versus slow and creamy smooth rendering.

A model I am working on has some unexpected holes or gaps. These look to me like they might be a rendering problem, rather than a structural problem.

Can’t find the old option to test this idea. Was it moved? Is there a new and better way?

I’m working in Rhino 5. Thank you for your insights.

Hi Michael - render mesh settings are in DocumentProperties > Mesh page. You can also set per-object render meshes in the object properties.


Many thanks, Pascal. And sure enough, the slow render option solved the problem with the image. All best, Michael
