Coating material tests
Coating material tests
Thought I'd make a new thread for test renders.
First off:
Interference from a thin coating, where the coating thickness is controlled with an FBM shader.
The substrate material is a somewhat rough metal.
All the rainbow colours come from light interfering with itself as it passes through the dielectric coating, which is a few micrometres thick.
A bit similar to one of Etienne's materials: http://www.indigorenderer.com/materials/materials/1065

Using a more accurate interference model plus turbulence noise:
Re: Coating material tests
I'm looking forward to play with that coating feature!
Only thing that kind is quite scary here is the SDS noise after 31min and 2500 samples/px -.-'

Re: Coating material tests
Yeah I'm not sure if the noise is a problem with the new coating material or not. Seems like it may be.
Re: Coating material tests
The coating material is looking cool!
I see it reproduces some kind of rainbow-y effect on the surface it is applied to: is it something depending from a specific parameter? For architectural mats I'd use coatings for varnished floor mainly, but they don't have such rainbows

Re: Coating material tests
That test have some special ISL code in the coating that creates that effect, its not per default mate!Pibuz wrote:I see it reproduces some kind of rainbow-y effect on the surface it is applied to: is it something depending from a specific parameter?

"Simple" coating looks like that: http://www.indigorenderer.com/forum/vie ... 37#p119037

Re: Coating material tests
..OPS! And I had already seen that!

Hi Pibuz,
The thin-film interference will be optional - it will be a checkbox on the coating material UI.

Testing absorption in the coating.
The red colour comes from the absorption of non-red light as light passes through the coating layer.

Re: Coating material tests
Make sure you have 3.6.2 installed if you want to try out the above materials!

Re: Coating material tests
To put it in other words, the material underneath the coating is a grey metal. Gorgeous.OnoSendai wrote:Testing absorption in the coating.

Re: Coating material tests
Doing a bit of work on getting the coating material going with transparent substrate materials.
Coating material over diffuse - diffuse-transmitter blend can be used to create quite a nice 'fast-SSS' material:
