Hey, things are moving nicely forwards. Machinima rocks!
I found out that If I have manual keyframes with my USD, and I import that to master scene, and drag the asset to timeline some where later that the first frame, then my keyframes are aligned wrong. See this video:
The solution is to move the asset track to very beginning in timeline:
Great! That fixed it.
But things might get overcrowded in seq…
Maybe you could think some sort of nesting / child-parent thing for all these tracks in seq? But you know better :)
