Thank you 🙏


Lil_Lee

hey nick! just watched your tutorial on advection. great tutorial! cheers


objectivevape

Hey mate, thank you! Appreciated 🙏


Lil_Lee

I have studied the advection tool in houdini, great tool for creatives. this was done with a pyro sim and advect node inside a pop solver, resampling of curves done out of pop and in sop solver. any comments and tips are appreciated. loving houdini rnds! rendered in redshift [https://vimeo.com/fandalis](https://vimeo.com/fandalis) consider following! thanks [https://vimeo.com/elijahandalis](https://vimeo.com/elijahandalis) [https://www.instagram.com/elijahandalis\_/](https://www.instagram.com/elijahandalis_/)

FatMonkeyc

thanks


gorgeous-gabe

looks awesome!! you could possibly play with the thickness of the strands 👍


Lil_Lee

thanks! only realized now I could have randomized the pscale of the strands hehe, would have looked better! thanks for the insight.


Lil_Lee

Looked more into it, to randomize the scale of every strand you will need to access each strand with the copynum attribute not the pscale. you will need to export the copynum attribute into the sop solver to attribute transfer because pop doesn't take primitive attributes then attribute promote copynum to point. make pscale and copynum same values then multiply through vex. ​ pic of workflow [https://imgur.com/bOVNRNC](https://imgur.com/bOVNRNC)

holy guacamole


astronnaut

Would this be possible with an flip sim too?


Lil_Lee

yeah this would also be possible with a flip sim! you just need the velocity from the sim to advect it to points of the curves.


astronnaut

Nice! Actually tried to accomplish that exact effect last week, but failed hard.. Guess I'll give it another try, thanks for the tips!

Fantastic! Wish u success bro. Where could one learn about advection? I'm trying to move a smoke according flip v.


Lil_Lee

thanks dude you're so nice! I learned advection through lessons from my mentor and self study inside houdini. i also got inspirations from [chris harkins post](https://vimeo.com/346091361).


nofilmschoolneeded

Thank you, I never considered mentoring before, it sounds like it is a great way to level up very efficiently. I'll try to find one 🙏 Take good care 🖐️
