Thanks, that worked. Although it took me a minute to realise that the hue adjustment ranged from -180 to 180, I had assumed it was 0 to 1. So I added a range node to the vertex map, and now it is all working. Still so much fiddling for what is one click in Modo. I know I have to move past it, but it ...

How would I apply this to vary the hue of a texture on leaves? I don't want to simply tint the texture. I have setup the weight maps and this works but I am not sure how I can feed that into hue adjustment of a Jittered Colour Correction node as the pins expect a float value not a texture. Perhaps ...

Yes. And at the end of my last post I explained why I was not using that.

The ORBX was a simplified scene; I've posted examples rendered from that below. But updated the ORBX to have both the diffuse and specular examples.

I've created confusion by posting those initial renders, as they are not generated under the same conditions, hence they have a very different ...

Oops, I forgot that was a Modo file. Here's the ORBX...

I'm doing a clear label with opaque printing on a plastic bottle with subsurface scattering and find that mixing any diffuse into the bottle material creates incorrect colouring under the label. Issues occur adding a percentage of diffuse and also using 100% sss with the diffuse transmission option ...

I'm doing a clear label with printing on a plastic bottle with subsurface scattering and find that mixing any diffuse into the bottle material creates incorrect colouring under the label. It gets more saturated. The diffuse problem is not just adding a percentage of diffuse but includes using 100 ...

Yes, but not cylinders.

It would be great to have Modo fur working in Octane.

I tried the emission but I did not like the results, removed shadows and it looked flat and unrealistic. Instead, I tried overdriving the albedo colour by unclamping the layer shader it is plugged into and increasing the exposure value on a colour correct node.
