Hey there. I'm working with fluid sims and FLIP simulations for the first time, and I'm wondering if there is a way to display the point colors outside of the DOPnet, the same way they look when I'm inside the DOPnet? When I'm inside the DOPnet the water is colored with a ramp based on speed, but as soon as I leave the dopnet, my particles turn grey. I'm working on adding white waters, and it's hard for me to see how the white water relates to the fluid object when I'm outside of the DOPnetwork, and trying to view both at the same time.

From velocity, you can re-calculate speed after the fact.
Drop down a point wrangle and use the following code.
After the wrangle, drop down a color node and choose ramp from attribute. Type "speed" and choose the whitewater preset to re-establish a similar look.
Drop down a point wrangle and use the following code.
f@speed = length(v@v);
