wireframe material with transparency.

[Shift Studio]

wireframe material with transparency.

Please see attached diagram.

Can anyone tell me how I can make the black/colour 0 go away?
So when I save as a .tiff, i'm left with the blue wireframe, and all else is transparent?
(right now the background is transparent)

Thanks,
--Shift Studio.

Plug the wire node into the transparency of the material. If needed, invert the colors (via a gradient node, for instance). Also, don't forget to check the IOR for the transparency (1.0 would most likely be needed here).

Thanks Andreu! I was kinda working my way towards that, but didn't think about the IOR.

Much appreciated.

What is the IOR and where do you set it?:redface:

Index Of Refraction

 

[Shift Studio]

IOR is the 'Index of Refraction'. As I understand it determines how the light bounces around inside a transparent material.
You set it in Material properties under 'Transparency'

Under the transparency section of a material, index of refraction (IOR).

I said it first :tongue:

Thanks guys. How does this work? How do you know if it needs adjusting?

it's a physical property of materials: http://www.robinwood.com/Catalog/Technical/Gen3DTuts/Gen3DPages/RefractionIndexList.html

If you have a single pane (Gel light-> diapositiv or alpha mapped polygons) turn it off - otherwise the scene behind gets distorted/shifted.
If your making glass or other translucent materials model the stuff and set the approbate IoR of that material.

That link is great thanks. I get it now.:smile:

trivial to most but...

This is what I needed to do. Makes sense now, but wasn't really obvious for me.

The blue in the first node becomes the colour of the wireframe.

It´s easier than expected - at least.
This one will render a solid wire against transparency.

:redface: man, that is easy. I sure have some things to learn about material building.

The interesting thing about the wire material is that it mimics real geometry on parametric objects - that means you can keyframe every parameter and the shader will carry on.
This is made just from a parametric box:

very cool! Thanks for showing it. I'm excited to try more and more things, including animation someday.
