Hack achievement of the day: for both a proper animation keyframe triggering system missing from the in-house game engine, and purely out of curiosity, I decided to try out a Time Modulator (shareset in Wwise) to then sync trigger sounds from within a Blend Container. Video cap from game with a sine beep on zero frame, read timecode from Reaper project. But it works! (Mua-ha-ha!)
It is nothing but cumbersome, yet a fun hack 🥳
