#1 rule: You can only 'tween with a vector level This video shows how you can use the inbetween function in OpenToonz. This takes 2 vector drawings and adds a number of drawings in between, transforming the lines/shapes from the 1st to the 2nd (transforming lines in the order they're drawn). First I run through the basics of inbetweening, then I explain how you can use the built-in 'Guided Drawing' feature to ensure that the correct lines correlate to each other and also how you can use copy/paste/edit to manipulate your lines/shapes. #1 rule: You can only 'tween with a vector level I try to speed through my explanations as quickly as I can, speeding up the drawing where necessary, so you're not just watching me draw, but there's a lot to get through and I try to give out as many tips as possible along the way, but if you want to skip through the video, here's the list of topics I cover.
