Hi!
Why then i enter expression in fields Size and center in GasVorticleGeometry node, she does`t work? :?:

hm… :?

Nobody knows?

If I set expression in Size and Center of GasVortGeo, then in GasVorticleGeometry->vorticle-> Box node does`t update. And Box do update if I change some param.

The gas vorticle geometry only uses the expression at the first frame. Thus, it doesn't update over time. This node is designed to just initialize the vorticles.

Thank you jlait!


How can I set those parameters automatic in first frame only, from VorticleRecycle node, only in frame 1?
I need this, I use a Resize node and then I change resolution of smoke fluid for final render, size of bbox is changed. And vorticles have spacing because of sizes vorticle geometry and smoke bbox is differents. hm… sorry for my bad-bad english, I try one`s best…
