can we get fog height control like vray next has and it is gpu too https://youtu.be/weqxEb5TYFY?t=124

One thing in playing with Hair shader I am seeing with BOTH (1) Melanin+Pheomelanin and (2) Albedo modes-
It is impossible to achieve a jet black color without pulling down roughness.
The only problem is that this then it creates a ridiculous amount of spec on the hair.

We will need an overall
(1) Specular adjustment control, and
(2) a Darkness control.

This way, we can, in any lighting, create soft jet-black dark hair without making it look super-reflective like mirror-hair.

Can we get a toon shader converter? Where with one click all octane materials like diffuse, glossy and secular will turn to toon materials with similar values and colors?

Thanks

Enabling AI light results in error:

device 0: direct light kernel failed

To make the Standalone work again it's restart is required.

@Developers - I get crashes too when activating AI light.

It's been a month and no OSX version??

Rendered volumes in 2019 are different from 2018. This is with "Emulate old volume behavior" option in kernel settings.

2018:

Fixed for next release.

Has already been fixed for the next version.

Baking camera renders black in this XB2, and for same render attempt with exact same setup, in 2019.1 RC5, Bake renders fine.

I wish I had tested this sooner, but better late than never...

This hair shader needs work. Look at this, on a primitive cube this is the darkest I can get it using the Melanin values.

And - When used in a Composite material with a mask layer, the mask does not mask it out, which I had been hoping since there is no Opacity channel yet.

On the color - With the non-Albedo Melanin color mode, It ideally should go from white to black on extremes, right?

So, to function in any lighting on any mesh, with a good result, HAIR shader needs:

1) Opacity channel
2) Darkness multiplier, or a more extreme combo of Melanin, Pheomelanin, or Azimuthal Roughness
3) A Specular amount to work with the Longitudinal roughness.
4) Fix so that it can be masked in a Composite

I know once it has working Opacity I could layer Melanin or Mix it with a darker 2nd Hair using the Albedo color mode, I guess, to darken it.
But it just would be better if it could work 'Out of the Box' with a full suite of parameter options (White to Black, roughness/specular extremes).
Otherwise it's like half-finished and always needs a workaround augment layer to make it look right.

EDIT

With Black Albedo, this is darkest I can get
