no it does not see this attribute, when I dive inside the first null on the pattern slot see this attribute but not the node itself.

Hi,

the problem is this field does not recognize the expression when I put e.g. @pattern or `detail("../NULL", "pattern", 0)` I would like to set the parameter in the wrangle like this setattrib(0, "detail", "pattern_node", s@pattern, @ptnum);but it does work.

Create a new wrangle with test detail attribute s@test = "name"; and connect before building_from_patterns node;

Check if the field can read this.

[building from patterns change Pattern with attribute]

If I understood you need to read detail attribute and use it in "Pattern" field of Labs, also split "pattern" into two values "BaseWall" and  "Floor01":
detail("../NULL", "pattern_group", 0)
detail("../NULL", "pattern_pattern", 0)

Try to split string with split function or so by symbol "<".

Hey

tried inside solver. It didn't work. I read the documentations of the vdb advect, as far I'm understood, it only works for sign distance field vdb.

Check this

[(Solved) Curl areas within density field conteiner]

For the setup you need to convert volume to vdb and put vdb advect inside solver.

Hey Fencer, cheers as always!  Can you elaborate?  Cheers!

Volume mask has values 0 or 1, windforce reads this values as on/off state, if you remap volue from 0 to 1 you will have gradient falloff for windforce.

Done.

With regard to the syntax highlighting, it's possible but it requires some hacking of the editors interface thing. I did it on the last version of the forum but forgot how. I'm pretty time constrained, but I'll try get to it soon. 

A bit inefficient in this case, we have three latest reply for one post in one "Posts" section. In theory, all "Posts" section can be filled with only one topic discussion.

Maybe there is a way to limit with one latest reply per topic in this section?

I suggest to start learning and play with more simple setups before diving into something like above. Start from a simple setup to prove idea.

[Simulating a stiff edged Z shaped cloth]

Need sometihng more complicated but as a start point maybe just a cloth will work. Check hip.

Let me know if the modules I added are working. These ones are built into the software vs a plugin, but they're less feature rich. I can investigate some more if these aren't good enough.

[Swirly Sand Sim]

Looks like you're on the right way with flip, do more resolution, add more swirl/turbulence as on ref.
To make it more sandy for render you can try advect pop with amount of particles required for this look or random remove part of particles like 20-30% from flip to make gaps between grains.

@Benyee  Hi, I tested your file it was working in simple transform scene but when I wanted to test it in an rbd scene the result was negative and the primdist kept deleting when it was less than 0.0005. There was deterioration on the outer surfaces as well, but I seem to have partially corrected them by separating and reassembling the surfaces.

Going with the solver as Benyee mentioned must be the way.

1. for geometry velocity blur you didn't calculate velocity on geometry level
