I have a pyro sim done, it looks all fine with the cache
but when I apply the scale noise in the pyro shader,
in both smoke field and fire intensity field.
they both keep fading in and out in a 20 frame interval just like my rest field setting in the pyro solver.
I don't know if this is the issue or not.
why would this happen and how to solve it?

I have attached the rendered sequence
please help

I have the same problem, my volume fades out at frame 40 and fades in again at frame 60, only when I use Scale(field*noise) mode in the Pyro shader and i don't know why
