Have you tried assigning each stream an ID attribute and then using the add sop to connect by attribute: ID? I’ve done a similar setup where I had leader particles dropping a stream of static particles behind the leader, and assigning each leader particle an ID attribute that gets passed down to the static particle “trails”. Then you can take your add sop and connect by attribute without having to use a ForEach node.

I’ve been working with Houdini to Unity workflows and have come across something promising to get Vertex Animation into Unity (which as far as I know hasn’t become readily available). I came across this asset for Unity - http://unitylist.com/r/1d7/unity-vertex-texture-fetch-animation [unitylist.com] which comes with a Max script for exporting deformations to a .exr VTF texture. I’ve tried loading the Houdini GDC vertex animation content, but haven’t had any luck with getting it operating. The sample file is one VTF texture that is dropped into both the RGB(base) and RGB(deform) fields. Trying to sort out how/if this is possible to export out of Houdini? Any thoughts? I’ve attached the Max script to take a look at what they are doing as well .

Thanks Enviob! I had found setFrame but due to my limited Python experience, I’m having a bit of trouble on the inner loop portion. Would I need to define the amount of frames from the hou.playbar call as a variable and then run a for/while loop? Or does Python have a way to do this with an if/else loop? I’m a bit more familiar with if/else loops than for/while loops from VEX scripting.
