As some of you have requested, I've made a standalone version of falling sakura petals feature from Bushy Leaves. Just like in Bushy Leaves, cherry leaves leave custom particles with 20% chance of dropping a cherry flower instead of a petal.
This pack does not require OptiFine or any of its alternatives to work.
