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 …
Sure, but: A) That doesn't help with the problem Jon was having, and B) That doesn't help with the problem you normally use the similarity transform for (pretransforming _only_ the stored data, with no run-time changes whatever) B is what you normally sim-transform for.

I thought Jon wanted to flip the Y axis without having lots of correction code, I think it works in that case. It also works in the asset import case: you have data in left-handed coordinate system, you can import it to a right-handed rendering system and only set the root Xf

But anyway, I was just sharing because you commented that "you can't just mirror without affecting vertex skinning, etc" -- I just wanted to point out that you actually can.
