No smoke in second exported video (Pyrosim Results 2018)
« on: December 20, 2018, 06:26:25 am »

Dear all,

I set 'show' for the '3D smoke' and I choose a nice view. Using F10 I export a movie; everything goes fine; the movie is perfect.
I change the view (and only the view), and I use F10 to export the same video but from a different view.
This time the video is still exported and written to my hard-disk, but there is no smoke in the video.... (the video still shows e;g. changes related to activation/deactivation of geometry elements, so the video is not simply a still shot of the initial state; everything seems OK, except for the 3D smoke)

If now I export snapshots using F11, the same happens: snapshots are written, but without any smoke on them; while smoke is very well visible on the screen.
When I record the screen to produce a movie, the smoke is visible as it should be.

This is not the case with 2D slices; these are always correctly rendered to the video. It only happens with 3D smoke.

For me it works to reread the results (refreshing results is no enough) prior to exporting the second video. But with a bit of luck this strange behavior can be solved in a future version...
Has anyone else experienced the same issue?
I did not test whether this is related to the movie file format or the settings for the movie export.

best regards,

That is very odd. Thank you for bringing this to our attention. I'll be sure to bring this up to the team and see if we can get some work scheduled for a fix in the future.
