Mutable Plugin mesh does not update in PIE

Looked at multiple tutorials and everything looks correct. Meshes change in mutable object instance properly. Parameters change during play with key press as expected, but mesh doesn’t change

The warning at the top of the screen
Customizable Object compilation out of date
is warning you about exactly this. Mutable is a little buggy but it works fine if you

  1. Within your character’s CO, disconnect your group pin

  2. Compile

  3. Reconnect the pin

  4. Compile again
    I know that’s ridiculous but after working with mutable for many long hours some things don’t update unless you disconnect the pin, recompile, and reconnect the pin again. I imagine it’ll be fixed in the next release, it is brand new after all.
