Fixed! That's what I was missing. Thank you so much Evan. I knew that Attribute Transfer was going to come in. Well done. Terence *What a great community of people we have here.

Hello all. I've managed to get much further, and am able to vary to point size of my particles. Thanks Evan for your help! BUT, I still cannot get the texture to properly line up with the fluid. Instead of seeing the Mandril in this example, the UVs are wrong. And I have tried every combination of UV nodes, to no avail. Frame 01 of the simulation should be the image of the Mandril, and the fluid particles emit from that and swirl around. Any ideas? Attached screenshot and project file. Thanks!

Thanks Evan! That worked. Well done. T

Thanks Evan. I really appreciate it. I'll see if that works. T

And this one shows how one of the point wrangles generates the density. After the Points From Volume node.

Hey Evan. Attached are a few shots of the setup. And the image file I want the points to be generated from. Thanks!

Evan, it works great from the grid. Thank you. But, I'm trying to make it work on a box geo that I made into a flip solver. That's how I'm generating my particles. Inside of the box, so they just flow over a surface. The particles stay inside the very very thin box. Maybe there is a way to make the particles you sent just stick to the grid and swirl around on it? Tricky, eh? Thanks!

Thanks Evan. I’ll have a look. Much appreciated. T

Hi all. I'm having good results using the flip solver and particles, using density to drive them mainly. Now I can't seem to figure out how to vary the size of the particles based on a colored texture. So all the particles have a unique size based on the colors in the texture. And the colors from the texture would be represented in the particles. As always, thank you for your advice. Such a great community. T

Hello all. I am trying to figure out how to have particle movement based on color, and the colors would be initially generated by an image texture. A flag with three colors, for example. How would I have the particles moving differently based on color? Different speeds, different flow, turbulence, etc. Yet still interacting with each other. The red particles would flow fast in one direction, while the green and blue particles would swirl in an opposite directions, for example. I will be rendering in Redshift. Any advice would be much appreciated. Terence
