I did get attach to work on begin play. I also tested to grip after begin play on player input and that worked as well with some minor interesting issues. It was resolved by checking “Generate Overlaps” on the root component of the gripped actor.
I use the vive controller mesh as the root to then align the gun against, and since a scene component can’t be the root it works with one caveat: The physics collision during grip only seems to account for the root mesh’s collision?
I can work around the issue with begin play by just adding a delay, so don’t change just because of me. Thanks!
