How to make the flash book more realistic?
Do you want to make a fantastic flash book? Do you want to make your flip book much more like a real one? You have to add some details to it. An ordinary flash book has only the basic flipping effect but still looks uncanny. To create a realistic flash flip book, I think add some shadow effect may be a good choice.
Find the “Page shadow” option and set “Left page shadow” and “Right page shadow” velum, the bigger number the wider shadow shows. The bigger “Page shadow opacity” velum stands for the heavier shadow.
