Matrix4x4 operations in 3.5

Unfortunately Unity 3.5 doesn’t seem to have the functions MultiplyPoint3x4() and
MultiplyVector(). Is there a preferred library or copy-pasted code snippet implementing
these operations?

Unity 3.X has those functions. Not sure why you expect they don’t exist.

I didn’t pay attention and tried to call it like I would Matrix4x4.TRS()… /facepalm
