Yet another SphereTool

No, you set [ruby]edge.casts_shadows = false[ruby] only on the diagonal edge dividing the two triangles making up the quad.
The other edges can be soft,smooth, hidden whatever - but do not set Cast Shadow to false for these.

I couldn't see how hiding those others helped, which is why I asked, so thanks.
Can I expose the diagonals through code, then soften them?
would I need to collect faces.each face.edge_loop.verticies, add an edge between [1] and [-1] then hide those?
will that do it? -
Does your code currently generate true native quads? (planar)
-
It is just a 'followme' sphere, so I assume yes, I can only show the diagonals by distorting after completion.

Basically, a QuadFace compatible quad is either:
-
a native quad (face with four vertices)
-
two triangles made to act as one unit (separated by an edges that is soft+smooth and cast_shadow: false)
The reason that cast_shadow needs to be false for the diagonal is that in case the whole mesh is made soft+smooth there needs to be a way to detect what is the diagonal - and since cast_shadow is on by default and it appear most people don't use this property I made that the "magic marker" for the diagonal. This allowed for non-planar quads in SketchUp.

So, it should be ok as is?

It would work. But maybe Rich has hoped for a triangulated version so things can be manipulated without ending up with the edge that SU's AutoFold feature adds. But then again, QuadFace Tools had a function to add triangulation and there is my recent AutoSmooth plugin that both addresses this.
-
is this what you mean?
@TT... does this look right, I applied to all edges, but could just do the diagonals if that's better. -
Thomthom nailed it. I triangulate everything using the QuadFace tools.
It will make for a better exchange of data from on app to another.

@Rich
would this do what you need
just an off axes sphere, with tri's -
There's something funky with that because none of Thomthom Ring Select/Loop Select are finding the edges.
Even trying to convert it doesn't work.
Thom can help here more than me. I do understand the property needed but generation of that property through code is not my bag....
Unless I am missing the obvious

No - just the diagonal should have cast_shadow set to false. Cast Shadows set to false is what marks an edge as separating the two triangles of a quad. The border edges should not have this set.
Also, I see that lots of your edges are 1 segment Curve entities. Why is that?
-
D'oh....
missed the edges that parallel

I'll exclude the original edges...

It's a rotated arc so before I split them with the diagonals, you can scale using 'move-tool' on the cardinal points.
for uv is it better if I explode the edge first?
john -
For UVs I won't matter. It was just odd to see a one segment Curve. I noticed it because the Smooth and Sort property was gone in the Entity Info when I selected one of them.
