Hello guys,
To make the carpaint of the car in the picture attached I used the C4D Thinfilm texture in a corona 7 shader. It works very well to simulate the real carpaint used on this concept car and very simple to make.
But since the version 8 of Corona, the C4D Thinfilm doesn't react in a same way. Same issue with Corona 9, and I must to reinstall Corona 7 to make new pictures to have the good shader.
Any idea or solution to have the good carpaint with Corona 9 ?
Thank you very much.
Laurent

Did you try using legacy material?

It was a legacy material. Same issue with physical.

Any advice guys ? Chaos guys ?

Hi there, there does seem to be an issue with the Thin Film shader. If it's not reported already, I will do so. I was having a look at some options and these are my workarounds so far.
1. Scanned material: 555f00prism

2. A Layered mat with the edge colour bumped up and fresnel

3. A layered with a Legacy mat & Fresnel IOR cranked to 999, Glossiness at 69% & a fresnel shader in the the colour texture slot of the reflection channel.

Maybe it's just time for an integrated thin film layer in the physical material.
-
IDK how you all make it, but to me it seems to behave correctly.

One more for fun ;)

Thank you very much. I will test them.

the C4D Thin Film shader still doesn't work with Corona 10 :( I'm disgusted.
-
Works physically correct. Set it in 'Absorption' channel of 'Clearcoat layer' (worth to know what thin film really is).

Don't work. check out my first post. :)
I know what is a thin film don't need a professor :D Just I use it in a different way for a different use.

'Legacy' approach - use 'Legacy material' - keep it 'simple (https://bonpote.com/en/the-5-basic-laws-of-human-stupidity/)'... It's magic. lol

If you are so good show me how to do exactly the same carpaint shader on the left.
It will be more efficient than words... :D

We do have this logged to look in to.

DS's one (in Citroen's marketing campaign by DLP Paris) (https://dlpparis.com/dlpparis/ds-etense-performance/) looks somewhat artistically modified. The real one, I suspect is mimicking 'golden' beetle's metalic-like shell (science behind) (https://www.scientificamerican.com/gallery/bug-alchemy-gold-and-silver-beetles-shine-with-structural-color/).
Haven't delved further in details, but just made quick example using Corona's Physical material and C4D's "Thin Film" effect with shortened bandwidth and set frequency (to my taste).
