hey guys,
I noticed a weird behaviour.
the fumefx gpu preview is completely different depending on the scale, see attachment.
I have been struggling to get my sim right because the smoke looks faded out in the preview but is completely opaque black in the render, like 99% different. So you never know what you get. Particular since a grid size decrease for a higher quality completely changes when smoke is dissipated and compared to the dissipation setting I use when using a lowres preview grid.
So you have no idea to what to adjust the dissipation strength unless you actually run the sim multiple times over a few days until you are lucky.
Now if the GPU preview would be trustworthy this would help a lot, but the preview seems to be really HQ for only gigantic sizes at least with my current settings.
