Adding a mist-emitter to scene increases UI response times

[DragonsSpirit]

Hi

I have experimented with the mist-emitter for a while. While I did not notice any differences in responsiveness (GUI) during the first tests, I got a problem yesterday. I had a pretty basic setup in higher resolution settings, and when I added a mist emitter (without any simulation done or whatever), the UI is like having millions of particles in the editor, every action like changing values makes the interface freeze for some seconds and then it works again. Same when navigating in the viewport. Navigation --> Freeze --> Change values --> Freeze.......

The only thing that helps is to sett the "visible" option in the display tab of the mist-node to "no". That makes it all normal, but no mist is simulated then...


Any suggestions on a solution?

For a high resolution the display times are large, only thing you can do to alleviate this is to change the "Quality" parameter in the "Display" panel.

We are investigating new ways of displaying volumetric data in the RealFlow UI, specially those that will improve the display performance.

Hi

When i change the display quality, I cannot display it in higher quality anymore after simulation. As if the display quality would define how the mist is simulated. That is why i leave it to "Best". Is that supposed to b the case or may it b a bug?

I tried that here and it seems to work fine. I can change the "Quality" once the mist is simulated without any problem. Can you try with a very simple scene? Maybe my test is missing something, but I doubt it.

Thank you.
