The biggest step is actually drawing a pool table. I did it before recording a animation.
In the video I first show how the final build looks like, took me an hr to make that. Then I open a new file. I copy the drawing of pool table from previous animation. Rest all the animation is done from scratch in the video.
Important:
f6 is keybord shortcut to creat keyframe
f5 to create blank keyframe.
I have used these keys alot in the video.
Also at one place I used ctrl+c,v to copy the white ball and make 3 more balls.
I actually have a recording of how I drew the pool table too, comment if you want me to upload that also.
The songs are all famous, YouTube copyright system will probably detect it and add info about them in the description.
