Thanks a lot for your efforts to help me out Enivob!! I'll dig in your files later this weekend, I'll let you know.
I also found this video: https://vimeo.com/130118827 [vimeo.com] … this is more or less the effect I would like to achieve. 3 semi-transparent colors blending in one Fuid sim.

Of course! You you'll find 2 files: one with no trial and and error opacity settings and another where I tried to. Thanks a lot!

Hi Enivob, thanks again.. I followed everything from the webinar. Also enabling the dual rest checkbox etc. It doesn't work out.

Hi Enivob, thanks for your reply. Actually I didnt use UV's. Oops.
The image I want to use for opacity is just a square flat grey colored jpeg.
- I've found the UV Quickshade node, but where do I have to connect it?
- See my node settings in images underneath
Thanks in advance!

Thanks Enivob, but it didn't work out. I've put a screenshot underneath, my settings are as you described?
I'm using a mid-grey texture to get a semi-transparent effect.
Note that I have used point colors (Cd attributes) to get 3 different colors within one material. Maybe I have to add something there?
Anybody?

Hi there everybody,
I have managed to make 3 FLIP Fluid colors mix within one Material. Basically by following two tutorials about Mixing Fluids: by Peter Quint http://vimeo.com/55764136 [vimeo.com] (from 13:39 min) and a webinar by Jeff Wagner http://vimeo.com/182074285 [vimeo.com] , from 39:20 min. With some extra help on this forum, it worked out and all looks nice.
BUT, now I would like to make an hairgel-like, semi-transparent mix of colors. Trying out different materials, it seems impossible to do this. It's like the Cd point attribute is overruling opacity? I'm using the Plastic material right now, but also when I try BasicLiquid, there's no opacity visible.
I also saw this ( http://www.sidefx.com/forum/topic/14223/ [sidefx.com] ) post on the forum, basically the same question, but it's still not working for me.
Happy to hear from you! Thanks in advance!

Hi there,
Thanks for the extra info. I've spent a lot of hours trying, but it doesn't work out. I've problably overlooked something, somewhere.
It's getting pretty frustrating, having to combine different tutorials, most of them outdated. In this 2012 tutorial https://vimeo.com/38879512 [vimeo.com] for example, I need a VopSop node, but it's nowhere to be found in H15.
I feel like crying and returning to Blender again XD. But I know Houdini has the technology I need for this specific project.
Would it be possible to take look at my uploaded file, you can find above? And show me what I'm doing wrong?
Thanks a lot!

Hi Peter,
Thanks a lot for your explanation! Much appreciated!
Unfortunately I didnt get it to work… yet.
I followed your example of splitting particlefluidsurface in two, by adding Delete nodes with differences in $VELOCITY Filter Expressions. (https://vimeo.com/55764136) [vimeo.com] from 16:22 min.
The problem I come across here, is that the particlefluidsurface nodes looks diffent in the tutorial video: I only have tab called ‘Parameters’ with ‘Surfacing’ ‘Filtering’ and ‘Regions’, so I'm missing the ‘ATTRIBUTES’ (v Cd) tab you are using in the tutorial. Maybe a difference in Houdini 12 and Houdini 15?
I thought maybe the Basic Liquid is part of the problem too. So I changed the standard Basic Liquid material, to a standard Plastic shader (with the use of Point Color selected). Unfortunately nothing happens.
Your last suggestion of separating Fluid Particles into two different objects. Is that possible AFTER the simulation is done? So after baking the particle simulation?
Also in the Jeff Wagner webinar i'm stuck on the render/Mantra part.
My ultimate goal is to render an animation, of 2-3 emitted fluids falling down, colliding with eachother in different colors. It may not be so difficult, but I'm doing something wrong.
My project till so far in the attachment.

Hi there,
Coming from blender 3D, I started Houdini a month ago because I'm particularly interested in Mixing Fluids. And Houdini has far more options on this matter.
This week I followed two tutorials about Mixing Fluids: by Peter Quint https://vimeo.com/55764136 [vimeo.com] (from 13:39 min) and a brand new webinar by Jeff Wagner https://vimeo.com/182074285 [vimeo.com] , from 39:20 min. I got both Mixing Fluid projects to work. In Render View the two colors combine and particles collide perfectly.
The problem a came across is: I don't know how to exactly RENDER the Fluid projects. Especially on the materials part. (I know how to add (Mantra) materials in Shop, cameras, lights etc). But, how can I add two different materials that collide with eachother in the Render View? Just like they do in the 3D Scene Viewport. I've looked around, but there arent't that much tutorials wich explain how to add materials to FLIP Fluid projects, let alone mixing fluids. Could can anyone help me out with this? Thanks in advance!
