Blender Rendering includes smoke in image render but not in animation render Today i open my pc to see my render has failed, there is no smoke in my scene.

I have made the animation and included smoke, the letters are fine but the smoke does not appear in the animation render.
I have rendered the scene with "Render Image" and everything seemed ok? but when i render animation the smoke does not seem to show.

I am sure it has something to do with the render process and i have spent hours researching this to no avail.

Thank you.
Ok guys i figured it out... and im an idiot.

Turns out the smoke rendering only begins at frame 2.
I never let it go past 1 :/
