Thank you kindly Christopher,Yes as far as I know, FE presents the whole points data as an array. Beside that, at this moment I just feel FE as much better solution for me (and for Olivier of course :) ), instead of H. Can't really say more for now. Also really need to say, while I'm not programmer, unfortunately or not I have to communicate with them every day, even in private life, so maybe I become a bit resistant. I think we all know how is going with this kind of people - one has this or that opinion, another has completely opposite, all long stories full of smart words. No need to waste your time on me, let's say in short :) Of course I've read everything you said here.thanks again...

VOPs simply iterate over these points and process the graph for each of them. Since each attribute is an array, at any time you can pick the value of any element with `Get Attribute` provided you know the point number. This is so straightforward that you can even do this outside of VOP/VEX, with the `point` expression for example. Sometimes it can be useful to define attributes that can themselves hold arrays, for example a list of neighbours, to then pass these down to other nodes for further processing. That's why they added that feature in H14, but otherwise there's no real need to directly create arrays yourself. Shamefully, I haven't used Fabric Engine yet but from what you're saying maybe they're just presenting the data differently by providing you with the whole points data as an array instead of letting you directly work on a per-point context? In any case, there's plently of good reasons to use Fabric Engine but this definitely isn't one of them—just wrap your head around how Houdini works instead, everything will eventually start to make sense :) On 3 March 2016 at 05:43, Anto Matkovic <a...@matkovic.com> wrote: Nope. I think the only way to create an array directly in VOP, is pcfind (pcopen that returns array), or array version of point neighbors. Or, to stack the 'append' node several times :). There are examples how to loop over arrays of indices, later in network, here:https://www.sidefx.com/index.php?option=com_content&task=view&id=3148&Itemid=412 By the way, had to do some pretty interesting networks :) for Kristinka Hair for H - while everything worked at the end of day, anyway. If you're around arrays and nodes, Fabric is waiting for You....

I understand you need to for-loop on each Ptnum and probably append the P values and this will buid an array of P.But you know what ? Well I can't manage to make it work. I found no example on the net (sideFX, odforce).The doc is just words, no schemes, no graphics.The examples hips are bizarre, not so simple, and use the old loop node. So I'm wondering if someone from here could provide a screen shot of how that should be connected ? Thank you :) ------ Softimage Mailing List.
