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.

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.

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).

'Legacy' approach - use 'Legacy material' - keep it 'simple'... 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
