No rendering phoenixfd 3dsmax frame buffer Tweet

[stephen00]

When i use the octane preview render, phoenixfd fire and smoke rendering with no error, but when i want to rendering the final sequence nothing appear, the scene rendering normally, but nothing from phoenixfd.
When i render a single image, the render start good, phoenixfd is rendering, but the rendering at sample 70 or 80 become very slow but not stop and the temperature of my gpu down, usually in render is 60 degree, but are become more 48 degree.
How to explain that ?

Thanks in advance
