I thought that the upres sim supposed to look like as the original except with some more details. But it look nothing like that. I thought that's the actual purpose of the upres. Isn't?

So i am looking for a way to make the original simulation to a higher resolution grid, and add some wavelet turbulence on top. Like in FumeFX, or like in every video I have seen with the upres node.
for example here: https://www.youtube.com/watch?v=Y_yti0cjwM0 [youtube.com]

but I think that the high velocity collision messes up the upres simulation. Am I wrong about this?

thanks for your attention!

I have downloaded your file, but its still not working.
In the upres sim the desnity still goes away.

here is a screenshot:

(the upres sim is on the right)

I have a simple Pyro simulation, with a high velocity smoke source. The lowres sim works perfectly. I would like to upres the base simulation, but it ignores collision, simply goes through the ground and the smoke density disappears.
I also tried the same scene in FumeFX, and it was working as expected.


the hip file is attached of with the current setup. Its really basic.
Is there some way to get the upres working, with high velocity collisions?

thanks in advance!
