Hi there! Just letting you know (and putting this here in case anyone else has the same issue), the Bind Data Baker in v1.3 does not work in Unity 2019. Tested with two different models and the only way to get it to work properly was to switch back to v1.2. It seems to create squashed bind textures from what I can tell, or maybe it just can't read the data properly and outputs barely anything.
Not urgent or anything! Since 2019 is considered more or less deprecated anyhow, maybe just add a note/disclaimer stating that v1.3 needs 2022, and for 2019 to use v1.2? Thank you!
