I hope this question is not plain stupid, I tried to look online and spent a good amount of time within the software to try and find the solution, but am stuck now.
I can't find how to achieve this.
So I have a picture with friends playing some beach ball game.
I want to add a movement blur effect, but only to the ball. Not to the friends.
Also, I'd like to try adding a movement blur effect to the sand a friend is spreading with his foot.
So... How could I achieve this ?
I found this thread, which applies to the regular blur, not the directional/movement blue.
Thanks in advance for your help !
