Tree Chopping & Transforming

You'd want to delete the tree object when it's been hit enough times and spawn a group of intractable logs that are in roughly the same shape as the tree

Having intractable logs would be pretty easy but it all depends on how youd want to approach it.

Scripts again would depend on what you want to do with the log when it's 'picked up'

If you have any specific questions I'd be happy to help further.

I have made a simple demo for you.

I don't know what kind of inventory you wanna use so i stop at

Chop tree -> tree down -> stump appear -> tree disappear -> spawn logs.
