I can see the mix in my viewport. Make sure you have applied the material by referencing the final output node, in my case, the mtlxstandard_surface.

Blocks can be the results of pushing the density too high in the shader. Try pushing density at the simulation level instead.

It's hard to say without seeing the file. New users often change parameters that an experienced user might leave at default values. The first thing I would try is changing the resolution of those spheres. Try making them lower res and simulate again. Basically rearranging where the points are on the surface might prevent them from latching onto something.

Sure there is. Use the Get menu at the top of this page to click Download. Scroll to the bottom and click Production Builds. You can install an old version side-by-side with the new.

Oh, yeah, I see it now. It works in H19.5, but not in H20.

Yeah, I'd call that a Guide bug. I don't think it is impacting the simulation, however.

For your example, try...
float a = 0.15 +0.15; float b = 0.1+0.2; int equal = 0; float threshold = 0.0001; if(abs(a-b)<threshold) equal = 1; else equal = 0; printf("%f == %f? --> %d\n", a, b, equal);

Isn't a single equal symbol used for assignment and double equals for comparison?
Have you tried (@Cd.r==1&&@Cd.g==0&&@Cd.b==0)
You can also do this inside a point wrangle with code like this...

Technical Discussion » FLIP OpenCL No Cuda usage?..

I see about 8% to 16% CUDA usage. This is after I have removed all collision and particle display from the DOPNet guides. I'm looking at a blank viewport while I simulate. If you dive inside the solver, you may discover there are over 20 nodes in the network with OpenCL checkboxes that are off. I manually linked them to the top-level solver checkbox using a relative expression.
Overall, OpenCL will run out of vRam at some point. It's best not to depend upon it during unattended caching. It does offer a small speed boost while developing the simulation.

Try clicking the down chevron next to the word "Copy1" on your task manager. Choose Cuda from the list. Often usage shows up in that graph.

To make lines from particles in motion, you use the trail sop followed by an add. You need to have id attribute turned on inside the popnet.
Check out this post for a way to deform once you have a set of lines.

You could try something as simple as a ShapeBlend between the two simulations. If we're talking about packed primitives, you just have points. Cache both options and shape blend half-way between them so when it settles, the points from first simulation are used at the start, and the points from the second simulation are used in the end.
