Smoke appears, but freezes.

I’m just trying out the smoke physics in 2.78. I’ve never tried to use it before

I’ve setup the domain and the flow as per youtubes I’ve watched, but when I play the scene smoke appears on frame 2 but doesn’t animate at all, I just have a shape of fuzz. This is the same in Internal and Cycles, CPU and GPU. In the videos I’ve seen there isn’t any parameter setup required to see the smoke animation.

I can’t find any other posts with this specific smoke problem. I’m a bit confused. Any ideas?


This is the problem. This is frame one, but that’s it, it doesn’t change or produce any more smoke and there’s no animation. I can make smoke work in a blank new project, so can anyone think of any setting I might have applied that would stop this working? This was created with the Quick Effect, so it’s not anything to do with the smoke settings, these again work fine in a new project.

Thanks.
