Expression used for nice bending
Is the command where you can just grab one bone and the following bones bend incrementally till they reach the selected endpoint.
great for nice bends and if you screw around with the last two variables 0,0 fallloff and value of each bone in the chain, you can get some neat effects.
Now you can this same effect without expression by just selecting your bones or select one bone using the groups (u can tell groups to autoselect all bones in the group) and hitting “e” for multi-select and you will get a nice bend.
