Effecting Phoenix FD with Tyflow? - kanujk - 07-02-2022
Hey maybe a stupid question, but i couldnt figure it out so far. How do you effect/control Phoenix simulation with tyflow particles?
Like the opposite way when Phoenix is influencing typarticles with the fluid force operator.
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-04-2022
Have you looked at the PhoenixFD official help files? That ones that show how to have 2-way interaction between rigidbodies and a fluid sim?

I look it up and down again, but couldnt find it. Im missing the explanation on how to connect it to make tylow lead the phoenix sim
Or im just blind and/or dont understand
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-05-2022
They're in the "PhoenixFD" folder of the sample file zip.
Explanations are in the 'README' notes within the flows.

I actually was looking in the PhoenixFD forum/docs. Apologies for the inconvinience.
Will study the files

Had the time to look into it. This is also possible with smoke/fire? Changed it, but nothing happened when running phoenix sim.
Also is this the only way to affect phoenixfd? Since i have couple tyflow setups done and just wanted to add smoke to it, i was hoping there could be a way without changing tyflow particles.
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-10-2022
Can you describe what type of influence you're referring to?
Just getting tyFlow to emit smoke/liquid is very simple...I thought you were referring to more complex 2-way interactions...
RE: Effecting Phoenix FD with Tyflow? - kanujk - 07-11-2022
Basically i wanted to make these particles lead phoenix smoke, just like the other way around when phoenix sim leads the flow of particles with the fluid operator
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-11-2022
If you want smoke to emit from particles you can just add them as a source in your PhoenixFD source helper. Just make sure you enable the particle interface in the interfaces rollout of your tyFlow object.
RE: Effecting Phoenix FD with Tyflow? - kanujk - 07-11-2022
Not just emitting the smoke, but following the particles. Like the smoke follows a line through the phoenixfd helper "followpath".
Right now im using the emit option, but does it not work with tycache loaded into PhoenixFD source?
Have trouble while running both sims since tyflow does update whole progress without changing anything for some reason.
Here is what i mean

RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-11-2022
Oh you want the particles to act like forces on the smoke?
That's more of a PhoenixFD limitation than anything...it doesn't very good force control like that. Closest thing would maybe be their Body Force helper which allows you to attract fluid/smoke with a mesh. You could convert your particles to meshes and input them into a Body Force and see if that works. And doesn't Phoenix have a spline force as well? Could try that.
RE: Effecting Phoenix FD with Tyflow? - kanujk - 07-11-2022
Will try it.
So tycache cant be used as a source for phoenix then? Or are there some settings that can make it work?
Problem is like you can see in the video, that tyflow is updating the sim from scratch when going backwards the timeline. Sometimes even when it just normally progress through the timeline, it starts the progress from 0 without changing anything...
Why does it do that?
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-11-2022
Did you disable caching?
RE: Effecting Phoenix FD with Tyflow? - Adam Trowers - 07-12-2022
Hey Tyson, just adding to this. In the Beta you could emit smoke etc in Phoenix from a tyCache, this doesn't seem to work anymore. I went from beta build of 21st December 2021 to the latest pro build last week. I will probably switch back to beta for now. Wondering if its a bug or one for Phoenix guys to look at? Possible its a Phoenix 5 thing though.

Yes... i dont know when or why i did it, but its disabled. Thanks

Hi Adam
Im using Beta and it doesnt work
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-12-2022
For emitting from a tyCache, you just need to enable the tyCache's particle interface in the interfaces rollout.

You mean this?
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-12-2022
Yes.
RE: Effecting Phoenix FD with Tyflow? - kanujk - 07-12-2022
But its checked, without phoenix emitting anything from the particles.
You think there could be some other setting hindering it?
Probably me again changing settings
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-12-2022
Actually you know what, I missed that you're on PhoenixFD 5....I'm still running 4. Technically that shouldn't matter because that checkbox merely exposes the generic particle interface of tyFlow to Phoenix...however, it's possible that the latest version of Phoenix has a bug or something causing the issue. Might be worth pinging ChaosGroup about it.
In my own codebase I control how PhoenixFD containers are read by the Fluid Force operator and such, but not how PhoenixFD reads particle data from tyFlow.
RE: Effecting Phoenix FD with Tyflow? - kanujk - 07-12-2022
Alright i think you are right about the bug.
Made a new scene and set it up partially again and it worked!
Thanks again
RE: Effecting Phoenix FD with Tyflow? - Adam Trowers - 07-15-2022
Glad you got it sorted Kanuk.
Tyson, can emit emit from a tycache but only takes the centre of the particle into account and not the mesh. Shall have a word with Svetlin over at Chaos to see if its an issue their side. Thanks!
RE: Effecting Phoenix FD with Tyflow? - tyFlow - 07-15-2022
To emit from particle meshes, you need to enable that mode at the bottom of the settings in their PhoenixFD Source helper.
RE: Effecting Phoenix FD with Tyflow? - Adam Trowers - 07-16-2022
Thanks Tyson, never had to do it before ha. Didnt think to check!
