Error Rendering FumeFx

Krakatoa for 3ds Max
1

Hi,

I’m getting a error when trying to render a Fume grid:

get_fume_fx_particle_istream() - Memory error during load of…

Using the latest build of Krakatoa 1.5 and FumeFx 1.2, both on Max 2009 and 2010.

Thanks in advance,

Carlos

That’s an error from the Fume SDK that indicates that the Fume sim was unable to be loaded into memory. Are you able to render this scene using Fume without Krakatoa? Also take a look at the Task Manager while the render starts, and check if you are running very high on memory.

P.S.
Are you on a 32 bit system?

Hi,

I believe the problem started after installed the latest build of Krakatoa or the latest version of FumeFx.
I had tested Fume render with Krakatoa last week and it worked just fine.

The same error shows up with Max 2009 and 2010. I’ve tested it on another workstation and it works just fine.
I have a 64bit workstation with 8Gb RAM and I I’m just testing some very simple Fume setups.

I’ve now re installed the older versions of Fume and Krakatoa, but the problem still persists.

Thanks,

Carlos

Does rendering in Default Scanline cause the same, or similar error? Do Krakatoa PRT Volume objects work correctly (They are somewhat similar)? Can you merge the Fume sim into a fresh Max scene and see if the error persists. Also please record your memory usage settings while the render is starting, but before the error is shown (if you can).

Hi Darcy,

It renders fine with Scanline and PRT works just fine. I have tried several setups, mostly just with a very low res Fume grid and a emiter, same error shows everytime when I turn the FumeFx button on Krakatoa render settings, same on Max 2010. Will try to record the memory usage tomorrow, altho the error pops up almost intantanously when I press render.
Since last week I installed the latest updates for Krakatoa, Fume and PWrapper. I tried unistalling them and installing the older versions and still no luck. I even did a System Restore to a earlier date before installing all the updates, but same thing.
We installed all the same updates on another machine and the error does not show up. Rather strange.Kinda running out of ideas.

Cheers

Really strange.
Out of curiosity, what channels have been allocated in the FumeFX sim?
If you have the Velocity channel Exported, can you exclude it and try again?
I remember vaguely people complaining about memory issues when exporting Velocity during production and would like to know if it affects your problem or not.

Other things to try - install a much earlier build of Krakatoa (something like Beta 6 or 7) and see if it causes the same error.

Hi Bobo, yep very strange indeed.
I did try with and without channels, it makes no difference.
Also tried with Beta 6, and no luck.
Gonna try to unistall Max all together and reinstall all plugins one by one, and see if anything happens.
Just tested the same setup on a 3rd machine and it works fine, so it seems the problem lives on my workstation, rather than Krakatoa.

Cheers

I did unistall Max and every plugin, then istalled everything again…but the annoying error still apears…arrghh! :frowning:

It might be worth it asking this on the FumeFX forums, too.

Hi, I came up with a same problem.

In my case problem was the file name of fxd.
If you have any “.” in file name remove it or replace it with “_”
and try.Of course, period before extension is OK.

It’s weird but worked for me.

Worth a try :slight_smile: will check that out tomorrow.
Altho the error shows up even without simulating Fume, just by adding the grid to the scene and turn on FumeFx button on Krakatoa render settings.

Thanks

Kinda ran out of ideas. I guess for the time being I’ll just have to jump on someone elses machine if I want to do some Fume renders with Krakatoa.

Oh well, this fine morning it seems to be working…just dont ask me how. I installed and uninstalled stuff so many times that now its working in Max 2010, dont have have it installed on Max 2009 though. Guess will leave as it, no more messing around.

still having the some issue,i don’t know realy way i tryed activating and desactivating different channel,some time it work with no problem some time it cause the some erroe post here ,any workarround or fix may help us

I’ve gotten these errors a few times, and I’ve found them to be two things I believe.

  1. This was pointed out by Bobo on the cgtalk forums and it’s that fxd cache files for fume don’t like to be as “fume_thing_v1…fxd”, but rather “fume_thing_v1_.fxd”.

  2. And this other time is if I sim something from frame 10-30, and I try to render the sequence from frame 1 or 0, or anything before the 10, one way I got around of that was writing out t he fume cache in PRT files and just telling it to load blank.

Hope this helps!
