How to render sub-d lines and mesh lines in Keyshot?
« on: May 27, 2021, 01:10:10 am »
I made this geometry, applied the material and set the view to rendered in Rhino.

How can I render the mesh lines and sub-d lines in Keyshot?

This should work:

- Completely unsmooth normals (Edit Geometry > Edit Normals > Minimum Edge Angle = 0° > Calculate Vertex Normals).

- Assign Toon material.

- Set very low Contour Angle for the Toon material.

I am getting this result. The mesh triangulation is appearing in the render. I want quad lines to be there and the ability to space them apart as seen in the original post. Moreover, toon material is really flat. How can preserve the gloss texture too?

The model in the scene you posted is not the same one as from the image in your first post, is it?

But to answer your question directly, no, there is no robust way to render wireframes of quad meshes. KeyShot currently does not support subdivision surfaces, so the outlines of subdivision patches cannot be visualized either.

Yes. It's a different one as I didn't save the model of whose renders I shared in first post.

Okay. And Keyshot is always going to automatically convert an imported subd to a mesh. Right?

Yes. It converts everything imported into a mesh.

hmm what about using nurbs rendering in KSpro?

There is no nurbs rendering in KSpro. KS converts everything imported into a mesh. Really, after Dries said this wasn’t possible, the matter was settled. If it was possible, he of of all people would know.

NURBS rendering

For the ultimate quality and zero tessellation, KeyShot supports the import and render of NURBS data.

Yes, I'm aware of that feature. I use KSPro. Even if you check the "import NURBS data" box KS still turns everything into a mesh. That's how it works. It won't achieve what archz2 is looking to do.
