Help Mixing Fluids

[canaydiin]

Because in 3D color mixing is much harder to appreciate. As light travels trough fluids, it gets absorbed by them which means you won't be able to see much going on inside of a thick fluid volume. This being said, 2D can be switched to 3D by simply changing the solver's 2D/3D mode.

Also, because each sample scene tries to showcase one specific use case in the purest/clearest way. There’s no scenes that feature adhesion & rolling contacts, or advection & color mixing, or viscosity in 2D either. If I had to create one sample scene for each possible combination of features there would be thousands!


That's really strange. Blue (0,0,1) is the exact inverse of bright yellow (1,1,0), and red (1,0,0) is the exact inverse of turquoise (0,1,1). This cannot be a coincidence:
there must be something in your setup inverting the colors, my guess would be either incorrect blending modes or incorrect passing of diffusion data to particle colors.

How are you writing the diffusion user data back into the particle's color channels? I used the sample code in the manual:

Code:

void LateUpdate()
    {
        for (int i = 0; i < solver.userData.count; ++i)
            solver.colors[i] = solver.userData[i];
    }

These are the results I get (red+yellow = orange):




What exactly are you missing or wish to see explained more in-depth? Documentation regarding rendering and diffusion is very detailed imho, each parameter is explained and there's usually screenshot comparisons of different values. It also includes code samples for typical use cases.

Well I guess I've should have said more examples as well then.. But also more information about the diffusion data, and some examples of it of doing different things maybe, as you said, it is explained in details and I could probably do the other features but i cannot duplicate the mixing part. Because I've even copied the example you guys have and I can't seem to get the same result. I have also used the same code from the manual. The only thing that I've put which is extra is the speed changing so I can pour liquid when I press a button.
