I'm trying to get fire/smoke working in Blender. I have Blender 2.77 running on Windows 7. To reproduce:
- Create a new file (Ctrl+N)
- switch to Cycles Render
- Select the cube
- Choose Object > Quick effects > Quick Smoke in 3D View header.
- Press Alt+A to play animation. Smoke appears as expected
- Go to the Physics tab on the newly created smoke object. Click on "Flow".
Smoke disappears and doesn't appear again when the animation is played again.
