Do you happen to have a list of all items that can be modified. Im trying to set every item on the server pick up and dispenser to 5x with 5x harvesting

Everything that you can chop, hack, or pick up can be modified. But player planted plant resources will probably need to be listed under GatherDispenserModifiers as well as PickupResourceModifiers. One category does the wild stuff and one does the planted stuff.

If you want to know the name of the thing. Just click on it and that's the name you use. Here's mine, but I haven't tried multiplying plant clones so I don't even know if those work or not, but they probably do.
