how to grab flip visualization color in sops?

[anupamd]

Im trying to grab the nice flip color visualization in SOPs. If I file cache out of dop-import in SOPS I loose the color after the file cache node.

Where is the color coming from and how can I use it in sops? *see attached*

the visualization is just mapping the length(v), speed, to Cd.

 

To recreate in sops, just put a vopsop down, I think its now a 'point VOP' in H14.  

 

Put a length vop down, plug in 'v' to get your speed.

Plug that into a fit VOP, set your source min/max to be the range of your speed

Plug fit VOP in to Ramp VOP, set your colors to be 0,0,0.9 at the left side (0), 0,0.9,0.9 in the middle (0.5) and 0.9,0.9,0.9 on the right side (1)

Plug Ramp VOP into Cd

Actually, that over complicating it...you can just use a Color SOP > Ramp from Attribute.   First create a 'speed' float attribute with the value to be length($VX, $VY, $VZ)

Or, in your flip fluid object, transfer color from the dopimport node that is usually just for visualization. This way the resulting color will always match the guide settings you have in dops.

Awesome thanks eetu
