My smoke is not animating at all I'm trying to learn how to animate smoke and I found this nice tutorial. I tried to apply the tecnique to my specific situation. Infact I've created a 2D animation with a man that brings his hand/lighter to the mouth/cigarette and he lights it up. Towards the end of the tutorial,the author wants to animate the smoke. Go to minute 7:52 to see what he does. It seems that he puts a keyframe at frame 1 of the timeline and the rotation values on the mapping tab on the node editor become yellow. I did the same,but in my case the X values inside the mapping tab did not become yellow. Now go to the minute 8.19 and you will see that he skips to frame 250 and he changes the X rotation value on the mapping tab to -130.4 and then he puts another keyframe there. This is the result that he gets. His smoke is moving. But I don't get the same result. In my case the smoke texture remains the same ! So,there is something that does not work in my scenario. Here you can see what I did. So,where I did something wrong ?
The problem is the adding of the keyframe - what it appears that you are doing is moving the mouse up into the 3D View and pressing I. This is adding a keyframe to the selected object in the scene. What you should actually be doing is hovering the mouse over the rotation value in the Mapping node (the value you just changed) and pressing I - this will set the keyframe on the node value (and make it turn yellow) so that it becomes animated.
