FumeFX and Ember

Hi,

So I’ve started doing more tests with Ember and FumeFX. Just like the spline test with the particles I am using two SimEmbers and EmberForces. If I use a geometry source, I would get sim times of about 36 minutes per frame on a sim that should generally only take 1-2 minutes a frame. So I replaced it with a simple source that takes up roughly the same amount of space, and now I am getting sim times of 1m 30s. Very strange. Do you guys have any idea what’s going on?

I’m very much looking forward to FFX integration so that we don’t have to use Spacewarps but I was hoping this would be a workable solution in the meantime. I was able to sim around 30 frames and the results, while I need to tweak the setup, are really promising.

Also worth to note is that while it’s doing it’s 30m+ thing when using a geometry object, it’s only taking up 1 core. I don’t know if this is on FumeFX’s end or Ember’s end but I’ve never had these problems with Max’s spacewarps.

Also, I wanted to let you know that I made the spacing very coarse on the SimEmbers to see if that had an impact but it didn’t seem to… and considering how fast it is with Pflow particles when used as EmberForces I don’t see the SimEmber being the problem.

Trying to isolate what’s going on. I turned off the solver (switched it from FFT to None) on the SimEmbers and blocked all sides. FumeFX still takes ages to build the voxels for the object. I noticed no speed increase. Hopefully you and Kreso can sort out what’s going on.

The initial state frame goes really fast but I assume that’s because I don’t have anything going on in the initial state Magma flow…
