I'm experiencing an issue with Corona 7 and Phoenix 44100. It will render 80 frames and then the last 16 frames are missing the smoke. I'll delete the phoenix source, add a new one and load the simulation, but I experience the same issue with the missing frames changing to different frames. The smoke is visible in the viewport, but nothing renders.
Edit: I tried to render out the vdb sequence using the Corona volume grid, but again, a similar issue occurs. It just stops rendering the smoke after a certain frame. Vray renders both no problem.
Any ideas?
