Hi Omar
Is there any course on Animation that was done by JL you can recommend so that i can watch also?
Hello. I don't think so, JL does other things, like modeling and shading. The animation monarch and ruler, the almighty and king of the frames themselves is and always has been Wayne. Not that JL can't animate, he can, just that it's not where he focuses his teaching. I guess the only course he fully animates is this one:
