Thanks for Your time, in 18.0.566 it You file also works with cache option.

Another question, I still have is rendering with v blur?

this does not work in any case here

The problem gets even more unpredictable as soon as particle are reaped as they die. Another point for v blur approach. But still found no way to use vblur

As soon es I keep all dead particles I the motion blur does work again. But now I have to deactivate/hide them with the prune node based on the “dead” attribute.
My initial guess was to use the “usd_flattenedprimvarelement” vex function to get the right value for the instance, but I need a index, and @elemnum does not work. the documentation is vague, to say at least.
I think it is not supported yet, but I do hope im wrong.

I tried the cacheLop, but maybe ( I mean chances are good ) I'm doing something wrong here.

The network looks like this for all cases, just the last one works

Should it work at all in version 18? As Karma is still beta and Solaris quite new, it would be good to know if I just keep running against a solid “not yet” wall.
Thanks for any hints
