Liquid changing color

[48design]

Hi everybody,

I'm trying to achieve the following effect with PhoenixFD 1.x:
I want to create a liquid that gets pushed through a pipe and changes color from blue to red from the beginning to the end.
Like water getting hot while passing through the pipe. Any idea? I find the help files and examples very confusing...

Thank you very much!!

use a material with gradient texture

Hi Ivaylo,

thanks for your answer! Sure, I use a gradient ramp for coloring. But how do I get this texture onto the liquid's surface the way it should?

Thanks,

no chance to do it with UVW dragging
use world mapping, or fuel based liquid with high temperature and cooling option. i know you need the opposite, but it is just question of rendering
here is the reworked scene, it uses the first method.

Thank you very much! I'll test this.
PhoenixFD seems to be very cool but it needs so much time for training...

works great!

THANKS! I never use other coordinate-mapping settings but "Explicit Map Channel".
The cooling thing also sounds nice but seems to be not that easy...
