Hi Pharan,
We have this walk cycle animation with footstep sound events.
The issue is that our animator triggers the second footstep 5 frames before the end of the animation.
Which is 5/30=0.166s which is under default mix time. So if I loop our walk cycle in unity and let the the mix to default I simply not get the audio event. When I set custom mix time walk to walk animation to 0 then I get the sound.
I'm not telling that it is bug for looping clips where there should be likely mixtime 0 BUT not in all cases there is perfect LOOP so animators using that mixtime to hide the small start and end animation position differences.
All in all may be you see it as bug may be it is by design. I just want to point out that if a sound event is in mixtime zone it won't be triggered.
Thank you, Marek.
