phoenixFD animation problem

[jackieteh]

Hi i have 1 liquid source with 3 simulator in my scene to simulate a water fall in 3 difference location, but everytime when i close 3d max and re-open, i need to re-simulate all 3 simulator 1 by 1, how can i skip this?
or is there a way to burn phoenixFD simulation into 3ds max key frame?

Thank you.

Hey,

Not sure if you mean that after you reopen Max the simulated caches are gone or you need to know how to make the simulators start automatically one after another? If it's the second one, go to Simulation, enable script and open the script editor. There is a ready piece of code there you can uncomment and you just need to paste the name of the simulator there, which will be started after the current one finishes. This way you can connect sim 2 to start after sim 1, and also sim 3 to start after sim 2.

Cheers!

hi thank you for your reply.

after i reopen Max the simulated caches are gone, so i have to re-simulate again and again...and i wonder if i send this file to render farm, do i need to open the file on renderfarm and re-simulate again? i don't think renderfamr can let me do that lol

Hmm, this is very weird. Can you check your Output cache directory to verify the caches are there while you simulate and keep an eye on them while you open Max? Are your Output and Input paths the same?

ah thank you for the help, i have solve the path issue.

about the script to connect simulator, do you have any video tutorials?

[Svetlin.Nikolov]

It's quite simple, check it:
- Create two sims - sim1 and sim2. We are gonna connect sim2 to run after sim1 finishes.
- Go to sim1's Simulation rollout, enable use Script and Edit...
- Go to the fn OnSimulationEnd function. There is a code there you should uncomment. It has to read:

-- ... or uncomment the lines below to start another simulator when this one is finished.
-- Don't forget to substitute the name of your second simulator:
sim = getnodebyname "sim2"
select sim
A_StartSim sim--*/

This is it Close the script window, run the first sim and when it ends, it ill fire up sim2. You can use this technique in your setup

This is awesome and time saving, but it only run 2 sim, i have 3 sim in my set up, sir

Just do the same for the third simulator and you should be good.

Hi, i am not good in scripting, could you please show me the code?

Hey - here you can check how this works - https://drive.google.com/file/d/1GK7...ew?usp=sharing

Thank you very very much for your guide, i will post the result here.

Hi, thank you for all the previous help, and i can upload my aniamtion to render farm today. but i have facing another problem with render farm,
i have go to phoenix FD simulator input to browse and link all my phoenix FD cache, click save and archive the max file, when this all done, i upload max file and phoenix cache folder to render farm, but when render, all the water are gone.
what have i miss ?

oh forgot to mention, the render farm guy asking me if i use absolute path or relative path, what is that mean?

Please help.

[georgi.zhekov]

Hey,
Absolute path is the whole path to the files - C:\ProjectName\Sim###.aur so Phoenix will try to load the files exactly from there.
Relative path is ProjectName\Sim###.aur - the ProjectName folder needs to be in the same location as the Max file. Using relative paths - no matter where your folder for the caches is as long as it is next to the Max file Phoenix will load them. Most of the render farms require relative paths.

Georgi Zhekov,

Thank you for your reply.
Is this also apply to all the textures in the scene too, which mean i just have to put all the textures, phoenix caches and max file into one folder, and then upload it to the renderfarm, best way for most of the renderfarm out there, am i correct?

[georgi.zhekov]

Yes, this applies to all the assets, but it's best to ask the renderfarm support how it should be set up for them.
