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, you can't, and that's not what I was saying. What I was saying is that if you want your system to operate completely without updates, you have to change the basis of the entire source data, which is correct.

Your "trick" doesn't do anything of the sort. It assumes you still go ahead and put the opposite side of the similarity transform at the end of the pipeline (the camera transform). That is not the same thing _as not doing anything_.

This is why properly functioning asset pipelines (eg., not Unity's, I guess?) just have a way to automatically sim-transform the entire dataset on export, so there is never any inconsistency throughout the code, such as hacking the camera matrix (like you did).
