I am having a problem with my fire simulation. It renders in preview perfectly, but when I hit f12 to render the frame, it doesn’t look correct.
Any idea what my problem is?
I attached an image so you can see them side by side.
Thanks in advance.
So I am not sure what the problem is here. These are the exact same setup, I just change the scene at the top:
problem scene:
http://screencast.com/t/UXnQ704sl31
No problem scene:
http://screencast.com/t/PzhbbkZ8bI8o
Any ideas why the same settings in both scene could look different? I have tried starting over from scratch. I want this to work in my scene, and I can’t get it to… Please help!
Here is the file with the error:
I cleaned everything out but the flame. I know the flame doesn’t look nice, but the problem still exists. If you change the scene at the top. you will notice, the fire scene works perfect
Wow, I am frustrated and embarrassed. The problem after spending close to 5 hours trying to figure it out, was… Fire is transparent, and when I marked my hdri as transparent background it reduced the amount that the fire was visible, because it was looking through to nothing… I feel stupid, but glad I was able to figure it out… I figured I would post the answer to the problem in case someone ever ran into this this as well.
Glad you figured it out! 
me too. I guess the preview doesn’t support transparency. what threw me was it looked perfect in the preview window.
