FFX 2.0a Creating Grid via MXS issue

[jrand]

Something strange happening with the preview window when I create a grid through maxscript.

I simulate the grid with the preview window open it updates as it should, ie the preview is showing the simulation as it progresses. When the sim is stop or finished the preview window retains the last frame, when I scrub it seems to loose connection with the sim data, ie it says "Frame Missing".

If I create an animation preview the resulting avi is correct.

If I render the render is correct.

For some reason the preview window is loosing the path to the sim data?

Here is the snippet I am using, there are no call to paths/gridtype ect.:

Code:

FumeFX pos:[0,0,0] isSelected:on width:100 length:100 height:100 gridSpacing:1.0 \--Create the Basic Simulation Grid
    SolverQuality:4    \--Add more Fume Properties to this list.
    MaximumIterations:100    \
    SimulationSteps:1    \
    MaximumStride:0.5    \
    TimeScale:1.0    \
    Gravity:1.0    \        
    Buoyancy:1.0 \
    Vorticity:0.5    \
    XAxisTurbulence:0.0    \
    YAxisTurbulence:0.0    \
    ZAxisTurbulence:0.0    \
    TurbulenceScale:20.0    \
    TurbulenceDetail:1.0    \
    TurbulenceSpeed:10.0

This works just fine in version 1.x

Any Ideas?

I tried your script and it created FumeFX grid without any paths at all.
Is it the same on your machine ?

Thanks

That is correct, the output field is blank, I did write a function (well a script with a function) to populate it, it seems to do what it is supposed to do, I had to add a try()Catch() because it seems to be doing something a little bit different than FumeFX 1.x. (since the script needs to work for both Fume 1 and 2)

Although I would expect it to just create the default path, it is no big deal if I can set it manually or via script.

Repro:

1. Use the snippet I posted earlier to create a new grid.
2. Add any source.
3. I set the path the normal way (click the folder button, choose a path and filename, click ok)
4. Start the Simulation

The Preview works just fine.

5. Stop the Simulation.
6. Scrub backwards.

The preview window goes blank and says frame missing

The preview window still doesn't grab the simulated data stream for some reason.

Little screen grab of the issue here : FFX20a_MxsGridNoPreview QT 15mb


To get around the blank Output Field, I wrote this script to set the Path/Create Folder/File Name:

It works in both cases if I create the grid manually or via MXS.
