Hi,
I am having trouble with wavelet simulation. I have discussed this issue with Domagoj Korak via mail. To not repeat myself I am just going to paste in the communication I have had so far (blue is me, green is Domagoj):
so the problem is, that when I start the wavelet calculation, it renders the first frame and then just stays on the second (keeps calculating). I partially managed to fix the problem by getting rid of my maya settings (!) and then it works for some time, but this seems to come back once in a while (and I have to get rid of the settings again).
We are not sure what exactly is happening when you do wavelet turbulence simulation.
To do wavelet turbulence first you must simulate Default simulation first.
Also make sure that you set Extra detail to Wavelet Turbulence mode in your FumeFX Simulation rollout.
What OS do you have on your system?
By not rendering the frame are you meaning on preview window rendering?
In Output rollout in Fume UI what you have entered under Viewport Update?
I am aware of the procedure to do wavelet.
I am on windows 7, Maya 2015 ext 1 sp5.
By not rendering I mean doing simulation once I hit the simulate button on the fumefx shape. The simulation window pops open, it runs through frame 1, starts frame 2 and stays on frame 2 with cpus running. In that state I have to end maya with the task manager. Deleting maya settings, loading exactly the same scene with the same default cache, running wavelet again then works.
Is it possible that something is corrupting some fume fx setting in the mayasettings? Can you tell me where fumefx saves it settings (like default path etc.).
So just to clarify: It does work now because I have deleted my mayasettings. The problem just came back within a few hours – but its fixable by just deleting the settings again. If there is a ways I could find out what causes the problem that would be preferred though.
Which version of FumeFX you have on your machine?
Please go to wavelet folder and see does FumeFX saves wavelet cache files after the calculating stops.
How many memory you have on your system?
Please go to Fume UI and take a screenshot of General Parameters and Output rollout.
Thank you for your cooperation.
so I am on the latest 3.5.7 (btw. my maya is 2015 ext1 sp6 (not sp5) while the other machine we tried on was 2015 sp3)
As it currently works, I can’t test out if there are files written. I did however do that test when the problem was there and it wrote the first frame (FumeFX_wt_0001.fdx) and then a frame without framenumber (FumeFX_wt_.fdx) but did not write the second frame.
32 GB, memory should not be an issue, because I tested it with the standard container, standard simple source, standard wavelet settings – and it worked with exactly that scene when I got rid of the maya settings.
Up until now I couldn't send a problematic scene and I thought it was related to my maya settings, but now I have a scene that doesn't seem to do wavelet sim. I am also on 3.5.8 now.
Please find it attached.
