Description:
Very important:__
- Play the animation or bake all dynamics to get the smoke going.
- Do not use GPU for rendering. The GPU is incompatible with smoke in cycle. It must go through the CPU processors.
- For the shader i change volume scatter by emission. You can change add shader by mix shader, and you can add glass shader to surface.

Since Blender version 2.77, smoke, fire and point density are compatible with GPU rendering.
