Hello,

I want to make each piece with random scale between certain value, like 1 to 10. Currently I have transform node inside "for each connected piece" with expression:

detail("../foreach_begin1_metadata1/","iteration",0)

But it making each piece to scale based on it number attribute believe. I need behavior more like this copy stamp node and fit scale in certain range with completely random seed in position for each piece.

Thank you.

A little late, but I've had similar problem and this solution worked for me and I want to share it if someone look in future for it. The easy way is to feed your simulation geometry into cache and than import it in POP network(you can set pop source as first context geometry). Therefore you will have particle emission from your RBD particles or your big smoke object like meteor, plane engine whatever. Particles from Particles. The second particles that are from POP are making tails with their points ant this points are connected into your pyrosource node which is than connected into volumerasterizeattributes. In this way you will have prepared input for your volumesource node in your pyro/smoke dop netowrk with suitable shape . Don't increase substeps. It is too compute intensive.






with above mentioned method (one substep smokesolver)



and without:
particles from particles
