SubD examples and models

Hopefully the beginning of a looong and helpful topic...

How did you render with a square grid without triangles? It doesn’t work out for me((

In QuadFaceTools plugin there is Convert Triangulated Mesh to Quads, select two triangles of one quad and run that tool.

You can use this tool with no visible hidden geometry for it.

After the Subd plugin, my model looks like on a screenshot. But when rendering a polygon mesh in Vray, I see triangles. I noticed that if the dividing line of the square is hidden, then it is not visible on the visualization.
It would be great if the Subd plugin itself hid this dividing line, or there would be some sort of automatic way.

This is more of a v-ray question, if V-ray doesn't have an option to render specific edges then you need to be a bit clever.
Render the shape then export the edges as a transparent background .png and combine the two.
Hera's a very simple example.

Thanks! This is a good idea)))

I'll logged it as something to look into. I just need to make sure it doesn't have any other unintended side-effects.

great model and impressive first post...

Cool motor bike!

(Ps these above videos are not my own videos, alas!

perfect! and a nice model idea

Thank you for your attention to this!
I noticed that the FredoCorner plugin does this automatically.

Wow - that's an impressible detailed model! Very nice topology as well!

Please no, or at least make this as an option one can toggle on/off, because in general hidden geometry is BAD.
IMHO it would be a more clean workflow to do all the modeling avoiding hidden geometry and only at the last stage, when finalizing geometry for rendering, select all the smoothed edges (select all geometery and then run "selection toys -> select only -> soft edges") and turn them invisible.

Fredo corner plugin has an option for this in "rounding parameters->borders->inner edges" and you can toggle.
I think that's a good approach, because it can be adapted for different workflows.

The solution is making the edges not only soft+smooth, but also hidden?

[rspierenburg]

That and using a Vray Toon Material that renders the subd'ed edges.

Yes, here I showed how this can be done with the additional selection_edge and Curic Deep Select plugins https://www.youtube.com/watch?v=eBCDTTtv2Hc
