How can I increase more and more details in a pyro sim?

Hello guys,

Please take a look at the image below.
I'm looking for the all options that help me to add maximum details to my pyro(fire) simulation.
In the smoke object, I tried to use a higher "Voxel size" resolution, but it doesn't help that much.

I would appreciate any ideas.

Voxel size is important but part of it would also be to find the range of values of your flame and temperature fields and rescale source range values in your shader so that you get variation where you need it.

Yup.

Voxel res that is greater than 1p pixel from camera view is redundant, so as long as you have that in a decent range,
it more comes down to what Tanto said. The default temp/flame ranges are very broad, and tend to render quite soft as the
transition in ranges is very smooth. Find more interesting min/max ranges to work with, and remap their ramp to "crunch"
the values more. This creates a sharper transition in values which results in those more crisp looking flames.

You can also look into sharpening the volume values as another level of crispy, but usually the ranges and remapping does
the trick.

also keep in mind that no amount of resolution or remapping would help if your sim is smooth
make sure to break up your velocities with detail appropriate to your resolution using the shaping tools like disturbance, shredding and turbulence

Here is great article by Jeff Wagner about the shaping:
