How do I add a function if it is greyed out?
for instance, I want to use translucency but it is greyed out?

Hello,

we are aware that some of the features which are grayed out are not really clear UX/UI-wise on how to enable them. We have a fix ready in our development build, which should arrive to you soon.
In the meantime:
Translucency requires "Thin Shell" in General Tab
Refraction>Thin Absorbtion requires "Thin Shell" in General Tab
Opacity>Clip requires a texture map in the Opacity Texture
Volumetrics require refraction to be enabled
SSS requires Refraction at lower than 100 value.

Hope this makes it clear at this moment,
Jan

Thanks for the new PBR!
This post may be playing into the direction of my problem. I have a beer bottle with contents. The bottle with the given tinted glass (recolored) looks good. The contents are giving me trouble. If I also use the tinted glass and color it yellowish I don't get there with all parameters. Only when I use a clearcoat layer does it turn out as expected. But that does not seem correct to me. Is it not?

Is the problem once more between chair and monitor...?

Do you want the complete scene?

how do you set a Translucency color in the new material? Other than the base color.

My uneducated guess is that it has something to do with "Thin Absorption".

I'm talking about this setting in the screenshot here that seems to be missing. is it missing for the time being or i just can't find it?
what mmarcotic's mentioning seems to be another setting in the refraction, not the transparency tab.

I'm missing the color tab of translucency too...

short thought of simple mind w/ eye on matter...
 
Dielectric first.
Its color (light wavelength) gets defined by absorption and scattering properties of medium (volume substance).
Sub-surface, transparency and/or translucency are then basically one and the same thing, just another medium property defined and differed by purity/clarity (homo-/hetero-geneity), density and thickness of its form.

Metals are much simpler and generally exhibit solely surface properties (exception being 100s nm thick - thin film).

Q's:
1. Dielectrics - How is nesting coming along?
2. Metals - Will spectral data get support (ie. sopra or n,k values)?


Some gentle mindset stirring is taking action.

To Fix this you need the material be 'tiled' in the material tag, volumetric materials somehow needs tiling (both for the legacy and the new physical material)
