You are welcome Stig glad to help out!
yes the @ symbol is used in the wrangle instead of a $ symbol
you are correct that the P and Cd are native attributes , as well as v and N, which is why you dont need to create them…it is best practice to declare them however…v@P and v@Cd
to declare a new type or access non native attributes in a wrangle node, you need to specify the type before the @ , f@ v@ s@ i@, for float vector string and integer respectively
if you want to create a local variable in a wrangle node, you can just use the c style notation float foo , vector fee, then use them in the code with no symbol, foo = .53; or fee = set( 1,1,1) . These will be local to this wrangle node and not added to the attributes of the geo

From what I could see, you were not applying the color to the particles
I put in a pop wrangle to set this. I also made a pop vop to do the same, just set the switch parameter to 1 to use the pop vop instead. The second vopsop will blend from one color to the other from one height to your yposy height.
the last thing is, in the attribCreate sop you are using the $TY<0 expression. However, this is only to your source particles, which never cross the threshold.
so the particles will change once the y value is less than 0.

This is referring to the bounced light samples, reflections, refractions and volume bounces
direct samples refine first bounces from the lights onto the objects diffuse and specular components

fur is significantly faster than previous releases
and I can say without a doubt that mantra is faster in H14 than H13, maybe not leaps and bounds or GPU speeds but much improved
show me a fast flicker free GI renderer with no limitations please. even arnold is not fast and flicker free, all my tests have shown them to be fairly equal when all tests are in
Mantra is faster on some and Arnold is faster on others, but in a production they all even out, except the price…..

i know that fluids and wires, and fluid and rbds work, but is there an example

is it even possible?

if you use a geometry chop, you import the id as well as the other attribs you wish to make channels then sort by attribute, id
this works well , just may be slow if you have lots of particles and long frame ranges.
