Copy/paste of state machine leads to read only "Custom Blend graph"

When I copied a state machine from one animation bp to another (different skeletons so had to “recreate” the animation bp and it’s smachine), all went as expected - variables invalid, animations invalid, so I could manually replace them, but the “Custom Blend” graph between all the states that were using it, became read-only and I couldn’t find a way how to make it writable.

Ironically only thing that helped is bug/missing feature I have posted a few days ago - changing custom blend to standard blend and back to custom blend “fixed” the read only state of the “Custom Blend” graph for the price of removing everything inside it (not that big deal when one has to recreate the whole anim bp, event graph and smachines). I have noticed this bug in 4.7.5, no idea about the other versions.

Hey ,

Are you copying the state network inside of a state machine and pasting it in another or are you copying the entire state machine node? I’m getting a crash (which I’m currently bugging) when copy/pasting the State Machine node itself.

Hi,

in this case it was like this:

  • I have main state machine
  • inside the state machine, there are simple nodes, but also another state machine which in turn has a few simple nodes
  • I have hit ctrl+c when I was inside the “main state machine” and had selected all the simple nodes + the “another state machine”
  • I have hit ctrl+v inside “main state machine” (opened) in the new animation graph

Hey ,

I was finally able to repro this (been a busy week). I’ve entered it as UE-14788.

Thanks for reporting it.
