Vellum Grains control when to start and stop the activation

[thejedi 0]

Hi everyone

Im trying to get vellum dop system to emitt particles only between certain frames (Please see attached picture)

Is there any ways of controlling vellum dop so that it triggers the simulation only at specific frames? something like $SF>11 & $SF<16 that one can use in the POP source's impluse activation?

At the moment it seems to only accept one rule of emitting at a particular frame  and it does not stop emitting

I tried setting the emission type to continuous but that doesnt work either

Thank you

try && instead of just one

Thanks Noobini for the tip. I tried it but it didnt work. Thanks for the tip regardless, Noobini. I like your name its very unique like mine

Maybe...
...verify that you have a one-to-one point correspondence between the surface geometry and the constraint geometry of the Vellum patch? 

...try Continuous again, using full frame expressions (since geometry does not add during substeps?
