This happens using the integrated Blender-Octane-Version (2.78a):

When rendering a smoke/fire-simulation that used "adaptive-domain", octane resizes the flame (looks like).
In the viewport - and viewport-preview everything is fine- but when rendering an animation it seems octane does not handle the adaptive domain correctly.

1. Open the blend
2. Select the Smoke Domain
3. Go to the physics-tabs and scroll down the smokeoptions
4. Enable "Smoke Adaptive Domain" checkbox
5. Play the animation for around 10 frames, then STOP simulating
6. At the last simulated frame press F12 to see what happens

System: Win7 64bit, GTX780, 32GB DDR5 RAM, NVidia Driver 375.95, Octane 3.04.4, Blender Octane Edition 2.78a, Octane Server TEST3

I don't see anything wrong... Could you explain a little bit more, what you mean?..

Im sorry, i made a mistake.
It happens when using an "additional-factor" for the adaptive domain.
In unrendered viewport it looks okay, but in rendered preview or final rendering it is wrong scaled.

1- Enable adaptive domain
2- Set the additional resolution to 40 (domain gets bigger)
3- Scale the domain back to touch the ground (gives more finer details)
4- Play the animation till frame 40 in example and then stop it
5- Compare the viewport with live preview or final rendering

Thank you for fixing this JimStar.
BUT there is still an isue:
When you try to render the 1st frame (where no adaptive domain appears) my NVIDIA-DRIVER, aswell as Blender crashs!
Ive noticed this when trying to render an animation.
As soon as te adaptive domain appears (begins at frame 2) rendering works.

Thank you again! Works now.
There is just one more small issue i´ve found, too: In rendered viewport-preview the simulation will not be actualized when going through the timeline.
It seems "rendered" (in viewport) only loads one simulation frame, independently of the actual frame-number.
Rendering works fine, general viewport works fine, too.

1- Play the simulation till frame 20 iE. Stop the animation
2- switch the 3d-viewport to "rendered"
3- press left/right-key to go through your timeline (backward or forward)
4- The rendered viewport does not change

This is not a bug.
Your domain must have "Reshapable" type to be refreshed automatically in a live-render...

Great- thank you!
