Hey @Jonathan_Blow @cmuratori I was watching your stream on animations - FYI, you actually can do a change of basis via similarity transform without affecting all intermediate systems, I wrote up how to do it here (see the "one weird trick" section):https://towardsdatascience.com/change-of-basis-3909ef4bed43 …
No, that is not what Jon was doing. He wanted the gameplay code to operate with unmirrored rotations but the rendering code to operate with mirrored. So the problem was communication between the two systems, since they're then opposite.
