I would need to know how I can transfer the color of an object in motion. To another object in motion. And that the color is permanent. I've tried it with the solver node, but it freezes the animation.

Thank you very much, sorry for my English. I am Spanish.

Are you trying to accumulate the color? Or it just transfers once for the whole time range?

Post a hip! It should work, so there's probably something wrong you are doing in your scene.

Yes. I don't can the accumulate the color. I need the color accumulate.
I need to accumulate, the color to create a map. For a simulation.

Thanks you!

Thanks a lot!

Fixed your solver.

Fixed your solver.

Thank you very much. I would not have been able to donit without your help!

I will try to understand the process.

With the change to the solver I made, the main difference to get it to work was which color you had on each branch feeding into the solver. Since we are adding color every frame, we need to add the color that can be added. We can add white to black, but we can't add black to white, since that would be the same as adding 0. Once I flipped which color was on which side, it worked.
