There is nothing special about material setup. For the most part I used A&D materials, with some minor adjustments, like Color, Reflectivity, Glossiness, etc.(nothing much, to write about).
There are only few things, I want to mention regarding material setup.
First.
From the very beginning I knew, that I will render Ambient Occlusion pass for post. Unfortunately, it is impossible to render AO through transparent objects. So I had to per-bake AO for nixie tube construction, inside the glass bulb.
In the next image you can see: On the left, object without AO. In the middle, freshly baked AO map. And on the right, object, with AO map applied.
Second.
For digits, I used “Blend” material with two sub-materials and mask:
Material 1: was simple “A&D”, with some minor adjustments.
Material 2: “Autodesk Generic” material, with Self Illumination enabled, to emit light.
Mask: “Vertex Color”
Then, I used “VertexPaint” modifier to paint soft transition between the two materials.
And third, but not the least, Hdri map was aplied as environment background.
I got this hdri map from hdrlabs.com
That is all, regarding material setup.
Can you send me the model file?
Unfourtinetly, it is somewhere in my pile of ded HDDs. 😦
So there really no way? 😦
Anyway, thanks for replying!
