increase smoke from 0 -> filled grid with blue particles

[menno_vandijk]

Hi,
I am trying to create a sim where smoke slowly starts to increase while following a pat. (so it is not starting with a plum of smoke) So I have a source object slowly increase temperature and smoke values. For some reason I get a completely filled simulation grid with blue particles before the smoke starts emitting.
Any idea why this happens?
(see max file in the attachment)

Ah, don't worry - the voxel preview is trying to be universal and at one point the cache files look to it like they are from a liquid simulation

To work around this, disable the Auto Range options and tell the Voxel Preview of the Grid Temperature to always show a range between 301 and 2000:



You could also set the Smoke range to minimum of 0.001 and maximum of 1.0, and you could even enable the GPU Preview further down below.

Hope this helps, cheers

Ah yeah, makes sense, thanks.
