1:43 FLIP solver set up
8:10 POP VOP with age ramp set up
10:50 Ramp Parameter explanation
14:50 POP VOP with speed ramp set up
21:56 POP VOP with age and speed set up
26:00 Final result / wrap up
In this video I'll walk though how to drive the viscosity of a flip sim with any attribute inside DOPs, using a POP VOP.
I don't cover the shading / rendering in this video, but I have uploaded the hip file to gumroad.

Thanks for explaining your thoughts on viscosity so clearly. Well done!
I love this tutorial and the way you explain things!
Awesome tutorial! Thanks a lot! Hope you will release more contents, I'm sure that you will have a good audience in the time, cheers!
Nice! looking great and clearly explained, keep it up!
Thank you so much jason!
Thank you Master!!! really valuable explanation!!
Quality stuff! Keep up the good work and thank you!
Thanks so much. I am definitely planning on making more videos but my pace is off at the moment. I’m booked for a couple months on a job but my plan is to make some shorter vids showing some stuff I’m learning as I work.
cool buddy! Its very useful, i hope u keep going
Very quality stuff, super clearly, super nice look. Thanks!
Thanks so much!
Thanks for this!
very very helpful! Thanks a lot!
Thanks you!
Damn I hope you do the meshing part. This was really good
excellent video, the part where you said save before you start tweaking after you already have settings you like, because its hard to get it back to the same...i literally had that problem with some vellum i cached out changed something and dang lol.
I find very dificult to get any information about very thin viscous liquids, like paint. At the moment the only breakthrough I had is that I need a lot of particles. Yet that comes with drawbacks where anything else needs readjusting the values for viscosity, surface tension.
In any case, awesome tutorial and well explained.
very very very nice
Thanks.
Great tutorial, how do you avoid having too many points? Is there a way to optimise that aspect a little bit; i.e vdbfying it on the way rather than at the end?
I would happily pay for a full tutorial covering the meshing, rendering and sim setup from scratch
A trick: watch movies on flixzone. I've been using them for watching all kinds of movies lately.
Anyone can hint on how to set up two separate FLIP fluids to interact? I know it probably is something super simple, but I am a little confused, like one being viscous and the other less, with complete control over the separate forces, etc. thanks!
Hi! great tutorial! I'd like to know if you have a tutorial from scratch? I'd be interested in buying it. Many thanks!
I don't but many people have asked so it is something I'm considering. Just need the time to do it.
absolute beginner here but I tried that with the SOP FLIP and can't get it to use age to change viscosity. Tried an attribute VOP but no luck. Can anyone help here?
I made this quite a while before SideFX had the sop level flip tools available. In dops when I use the popvop to change the viscosity based on age, because this happens within the dop context it applies these lookups based on the previous frames values. I’m n short the vop acts as a solver, operates on the previous frames values. This doesn’t happen in sops by default.
Try to use source_first_imput instead of volumesource1, for me it works only this way
@@WhatIFound This explains a lot (the vop acting like a solver), thanks for putting that in writing
If you ´re gonna teach something, start from scratch.
