Create: Randomize Filters (1.20.1)

Set your desired blocks you want to be randomly placed when you’re on a train or a contraption. You can either set a filter with equal chance of being placed, set a filter where you can set each blocks percentage chance of being placed, or set a sequence filter so the placed blocks will follow a set sequence pattern set by you.

This works on both Trains and Cart Contraptions, Deployer and Rollers.
