Thin Film shader and the new Physical Material

[Cinemike]

The Thin Film shader that used to work well with legacy isn’t doing much (good) with the new physical material.

I’m refering to the attached scene and the image rendered with it:
Top row (please forgive the exaggerated settings to prove my point ;)) shows metals, left a legacy material metal with thin film straight and undiluted in the reflection color.
The next two are physical materials, one with thin film straightly put in the color slot again, the other one with thin film in the clearcoat property where I thought it would make more sense.
In both cases, nothing really happens, thin film-wise.

Bottom row shows dielectrics, left legacy again, next to it two physical materials, one with thin film in the reflection color, the other one with thin film in clarcoat, something happens here, but the result is rather … unexpected.

Win 10, C4D R23.110, Corona latest available daily.

Thin Film shader still does not work with Physical Material in Corona 8.

Hi there, how are you trying to use it? Just checked it here with V9 and it seems ok?

[Cinemike]

Try metals.

@Cinemike

Try metals.

Ahh, yes. You’re right. Okay, bumping this once again.

Hi Beanz,

Your attached example looked really nice, to which channel do you add the Thin-Film shader? And I was curious, does it only work with Metal presets? Thanks,
