Smoke render: 1 frame with no color?


The image attached shows 3 sequential frames of my smoke sim.

Everything seems to be going OK but some frames are losing the smoke color.

The sample attached shows the green smoke losing its color for only 1 frame, and I have other frames where both colors are missing and the smoke is just a simple black outline. I will post an image of this as soon as the frames after it render so I can post sequential images again.

I think its the Smoke Dynamics Bake that is broken… I’ve tried to re-render this frame on several different computers, all with the exact same results.

Any idea what caused/causes this? I’ve been seeing entire blocks of smoke vanish from one frame but come back in the next, and now this color drop out…

Thanks for taking a look!
