Vellum Grains ID

Recommended Posts

Hi there,

 

I was trying to make point IDs to work with vellum grains being emitted.

 

I went into the vellum source, and there is a couple of wrangles already in place to update IDs using the "nextid" detail attribute, just like a pop solver, but it is setup in a way that it just does not work, I did modify the VellumSource switches so it actually update the IDs, I am putting the file here so you can have a look.

I find that change very non elegant as I have to open the source HDA, do any of you guys know if there is something I am missing to get IDs to work out the box?  I know I could also use a sop solver and do my own update of the IDs, but since there is something already there in the source, I am not sure if there is a toggle or something I am missing.

 

Thanks.

Hernan.

Hi, yeah I tried that originally, but only did set "nextid", forgot about the "id" so I was getting -1 as id on the first frame haha, thanks!
