Who to give the final touch to a pyro fx efects with fluid in Maya?

Hello that such young

I have a question about fluids in Maya to make explosions.

in the previews, the explosion goes well, but when doing a render

the clouds of the explosion did not leave, the explosion bone is flat and I get like low resolution.

I do not know if something is missing or leftover, which is safer.

I show three images one is the preview that looks good if the render was like that,
the second is the render and the third are the points where I do not like or one hundred is wrong rendering.

beforehand thanks for your support.

greetings.
