more foam

[mhaze]

Here's a blue version with less plasticy birds - some of them seem to have too much displacement so I'll have to do yet another render.

Quite an improvement. But I think the blueish tint would look best where the milky water is. So make the milk blue
Maybe the displacement of the birds is a little bit too strong. Or too large. At the moment they don't look like plastic anymore, but a bit like plaster.

Cheers Hannes - I've been trying to make the milky uprising water blue but haven't found a way yet.  The birds should be better on the next render.

Funny! Without knowing, what I am doing I added another blueish (density 0.3, colour light blue) water shader and connected it by a merge shader which was driven by something I was hoping to be the right thing.
Image one: the result. The water is blue where it's supposed to be, but the rest looks like a biblical plague, and I don't know why .
Image two and three: the settings...

Yeh, I had that happen to me on one of my experiments not sure what's going on. The foam bit looks good though. I think I have a way to do it but I'm going to have to rewrite the whole surf setup

Hi Mick,

May I have a try at this one?
I have some ideas on how to do this a bit more simple. Using the mix controller for merge shaders never really worked for me.
If I may, could you accompany it with a sketch on where you'd like to see the blu'ish accents?

Cheers,
Martin

Sure TU go ahead.  I've found a solution but it ain't elegant.  Just connect the ouput from the colour to greyscale node to the density 1 input on the water shaders The bluish tint needs to be where the greyish upswelling foam is close to the rocks, see Hannes image.

You can do this for bluish water near rocks:

Interesting - that might well be it.

Very nice image mhaze !

Ulco, could you try your technique with the "Volume" controls in the water shader? Its density can be controlled by a function. "Volume 1 colour" can be white, but when this combines with the "Decay tint" which you would set to a blueish colour you get a more chromatically rich range of colours. White-ish where the volume is most dense and blueish where it it fades away. The intensity of the colour will depend on the relationship between Decay distance and Volume 1 density. That sounds a bit complicated, but think of it as some white material (the "volume") suspended in a blueish water ("decay distance" and "decay tint").

Totally forgot about that. Thanks, Matt.
