Is Grease Pencil good? What can you use it for? Can it compete with commercial softwares? After this video you should be able to make your own mind.
After using Grease Pencil for over 3 years, I had to make this talk about all the features. For me, Grease Pencil has been a life changing tool for both 2D and 3D work.
Hope you enjoy, cheers!
