Blender-FLIP-Fluids VS mixbox

If all else fails, you may want to consider a premium addon like FLIP Fluids, which in my experience feels more stable than the default fluid sim, though it may be a bit costly. Consider trying the demo.

For troubleshooting conflicts between addons, it can help to test in a fresh Blender environment with default settings and installing/enabling addons one at a time. In case it helps, we have some instructions here for how to backup user-preferences, test in a clean environment, and then restore your original addons and settings: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Baking-Crash-Troubleshooting#testing-the-flip-fluids-addon-in-a-clean-installation-of-blender

There's a free demo if you would like to try it out: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/FLIP-Fluids-Demo-Addon

The above was built from the code on the GitHub repository, which is under the GNU General Public License. This license allows for redistribution. Unfortunately, I do not have binaries for MacOS or Linux since I only use Windows. Also, note that the above download is for Blender 64-bit (which should be the default on the blender.org downloads page). The GitHub version doesn't have pre-made materials like the paid version on Blender Market. (Note: The demo file on GitHub has watermarks on the simulation. This is the full version of the addon, not to be confused with the demo.)

Make sure that your objects have correct manifold/closed/watertight geometry. See this topic for more info and how to verify geometry: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Manifold-Meshes

This is also an open source project and we provide a free version with the source code here including build/compile instructions: https://github.com/rlguy/Blender-FLIP-Fluids

Thanks! Mostly by reading through the FLIP Fluid Wiki and watching some tutorials on YouTube.

The related documentation for how to enable and use attributes (such as the color attribute) is here: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Domain-Attributes-and-Data-Settings

spectral.js uses the same paint mixing algorithm like Mixbox but is permissibly licensed.

This simulation uses the FLIP Fluids addon. There is a feature where each inflow emitter can be set to a different color and this is rendered using Blender's attribute system. The addon uses the Mixbox technology (https://scrtwpns.com/mixbox/) to simulate the mixing of the colors.

This is from 2015. Hardly news. Also, there's already a program that simulates realistic color mixing: https://github.com/scrtwpns/mixbox

Is anyone plug the Scrtwpns Mixbox into the Paint Software(Especially Procreate or Photoshop)? https://scrtwpns.com/mixbox/

maybe with https://scrtwpns.com/mixbox/ i should try it out ! seems fairly straightforward to implement.

The colors were chosen as a test example because blue + yellow should mix to green in real-life, but is more difficult to simulate correctly and less common in computer graphics software (More info on the technology we're using).
