What I'm trying to do is randomise UVs on packed geo per copy.. but rendering in Arnold..

Hi there is a statement in the documentation
“You can now create shaders the new Houdini way in /mat in the arnold_materialbuilder vop network as well as the old way in /shop in the arnold_vopnet vop network. Use the material flag to enable picking of the vopnet as a material at the object level.”
But I cant get it to work. The thing is that I would like to use some houdini nodes in shader creating which are not available in arnold_vopnet1 (like “Render State” or “UV Transform”). However a simple example not working for me. Please see attachement
Using H 17.0.506
Htoa 4.0.1
Arnold 5.3.0.1
Thanks.
BK

I'm heading to a mountains right now, but as soon I Will be back I will give it a try. I'm sure it will be alright. But what I'm not sure is how the feedback loop working now.
I thought this: it will go through loop and every iteration it will copy the objects. These objects will inherit the current “value” from metadata, so I will create say for example the pscale. So every new “generation” of objects will be bigger as a “value” or “iteration” matadata growing.
But it is not really this way?? It's like these objects, all of them growing every iteration, even these old from previous iterations?
I tried to delete previous objects inside the loop, but it's not what I want, I want scatter on all objects from previous iterations..
But, If I pass the detail attribute to a point attribute. I see they are growing in spreadsheet.. I'm not sure I made this clear…. But anyway. Thanks a bunch!

Hi there,
is there a way to have just last iteration of the for each loop? I mean the last “generation” ?
Im scattering points, looping a copytopoint node. So it is growing mesh. But i would like to have just the new ones every frame. metadata from each loop maybe, somehow?
I also have a popnetwork after scatter, to get age and tried to use “Just Born group”. But I still get the whole (growing) mesh every frame (for obvious reasons)
Iteration Method is by count. Im rising iterations with $F.
Thanks

Hi, some workaround to transfer UVs? Like I have a mesh from “Capture Reality” than run it through an “Instant Mesh” but transfer attribute UV not work very well.
